=Wounds of the face= heal remarkably well on account of its great vascularity. If severe they may leave great deformity or disfigurement, which may be the ground of a civil suit and thus require the testimony of a medical expert. If the wound involves the orbit or its contents it may be more serious, either from a fracture of the thin upper or inner wall of the orbit, separating it from the brain, or from extension of a secondary inflammation of the contents of the orbit to the brain. Wounds of the eyebrow may cause supra-orbital neuralgia or amaurosis from paralysis of the upper lid. Some fractures of the nose, especially those due to severe injury near the root of the nose, may be more serious than they appear. For in such cases, of which the writer has seen several, the fracture is not confined to the nose, but involves also the ethmoid bone and its cribriform plate forming part of the base of the skull. In such a case a fatal meningitis is a common result.

=Wounds of the neck= are very rarely accidental, more often homicidal, but most often suicidal. In nature they are most often incised wounds. As we have already seen, the kind and condition of the weapon used is often indicated by the character of the wound. We have also seen that in many cases a suicidal wound of the neck can be distinguished from a homicidal one with more or less probability or even certainty. Wounds of the neck are often dangerous, and they may be rapidly fatal if they divide the main vessels, especially the carotid arteries. Wounds of the larynx, trachea, and œsophagus are grave and often fatal from entrance of blood into the air-passages or from subsequent œdema or inflammation occluding the air-passages. Wounds of the sympathetic and pneumogastric nerves may be fatal, and those of the recurrent laryngeal nerves cause aphonia. The situation of the average suicidal or homicidal cut-throat wound is in front, generally across the thyro-hyoid membrane, sometimes dividing the cricoid-thyroid membrane, and not at the side of the neck where the great vessels lie and would be more easily divided. The force is expended, as a rule, before the great vessels are reached. The epiglottis may be cut or detached and the incision may even reach the posterior wall of the pharynx, but the majority of the suicidal cases recover with proper treatment. The homicidal cases are more often fatal from division of the great vessels, though, as already stated, in either class of cases a fatal result may occur if the air-passages are opened from the entrance of blood into them and the consequent asphyxia.

CONTUSIONS of the neck may be so severe as to cause unconsciousness or even death. The latter may be due to a reflex inhibitory action, as in cases of death from a blow upon the pit of the stomach. As a result of such contusions we may have a fracture of the larynx usually confined to the thyroid and cricoid cartilages (see Fig. 20). This may be followed by hemorrhage from the larynx, some of which may pass down into the trachea and threaten death from asphyxia. Later emphysema often develops throughout the tissues of the neck, and there is great danger of œdema of the larynx. The prognosis is serious unless tracheotomy is performed early or the case is closely watched. It is most serious where the cricoid cartilage had been fractured, as this requires a greater degree of violence. Whereas incised wounds of the throat are most often suicidal, contusions are most often accidental or inflicted by another. Among the latter class of injuries may be included the so-called _garroting_, by which a person is seized violently around the throat, usually from behind, and generally with a view to strangle and rob. In such cases the larynx or trachea may be injured in the same way as by a contusing blow.

WOUNDS AND INJURIES OF THE SPINE AND SPINAL CORD.

Injuries of the spine resemble more or less closely those of the head. FRACTURES OF THE SPINE generally occur in combination with dislocation, as fracture-dislocation. Thus displacement is generally present and causes a fatal compression or crushing of the cord. When the cord has once been crushed at the site of the displacement of the fracture-dislocation there is no hope of its ever healing. Therefore the lower end of the cord is never again in functional connection with the brain. These injuries are more rapidly fatal the higher up they are. If the injury is above the fourth cervical vertebra death is nearly immediate, for then even diaphragmatic breathing is impossible, and the injured person dies of asphyxia. Fracture of the odontoid process of the axis, which regularly occurs in hanging, may occur from falls on the head, etc., and is not always immediately fatal. Thus in one case[666] the person lived fifteen months and in another case sixteen months. In the latter case the fracture was due to the patient turning in bed while his head was pressed on the pillow. In some cases it may be questioned how far this injury may result from disease of the bones or ligaments. Therefore a careful examination of these parts should be made after death, which will usually enable us to answer this question, which may be brought up by the defence. It is hardly necessary for our purpose to enumerate the symptoms of fracture-dislocation of the spine. Of course the patients are almost always unable to walk and so are bed-ridden. A marked feature of fracture-dislocation of the spine is the length of time intervening between the injury and the fatal termination, and yet the injury is wholly responsible for the death of the injured person. This delay may last for months or even for years with careful treatment. But sooner or later the case generally ends fatally, though not necessarily so. Where the cord has been entirely crushed the result is almost always fatal; where the cord is not so injured recovery may and often does occur. According to Lutaud, fractures of the spine are sometimes followed by secondary paralysis coming on after healing of the fracture. At the outset we can seldom give a definite _prognosis_, which can only be given after watching the developments of the case. The prognosis is more favorable in fracture of the arches alone or when the injury is in the lower part of the spine and not very severe. The commonest cause of fracture-dislocation of the spine is forced flexion of the spinal column. Injuries to the spine are generally the result of falls or blows on the spine, especially in its lower part. Lutaud[667] states that after forced flexion of the spine without fracture paraplegia may sometimes occur, which is attributed to forced elongation of the cord. This paraplegia, which may seem to be grave, is completely recovered from as a rule.

Incised or punctured wounds of the spinal cord are rare, as it is so well protected except in the very highest part behind. Here between the occiput and the atlas and between the latter and the axis, and to a less extent between the axis and the third cervical vertebra, the cord is more exposed, owing to the narrowness of the laminæ. It is here that _pithing_ is done, which is almost instantly fatal, as the medulla oblongata and upper part of the spinal cord are the parts injured, and they contain the respiratory and other vital centres. Pithing may be done with such a small needle-like instrument as to leave scarcely any trace. Only a slightly bloody streak may persist, which may appear superficial if the instrument is introduced obliquely. Such a mark in this location with no other apparent cause of death should always lead to an examination of the upper part of the cord, which will always reveal the cause of death in such cases. Pithing is practised especially in infanticide.

As with the brain, so with the spinal cord, we may have CONCUSSION due to the shock of a contusing blow. Concussion of the spinal cord, as of the brain, may be fatal without showing scarcely a mark of violence externally or internally. As the cord is so well protected from injury, it must be extremely rare to have concussion of the cord without some actual lesion of its substance. As concussion of the cord is not often the result of the injuries of which we are treating, but rather of railroad injuries and the like, it will not be considered at length in this connection. As a result of a blow or fall on the spine or communicated to it, hemorrhage may occur in the substance of the cord or around it between or outside its membranes. In very rare cases such a hemorrhage may occur spontaneously as the result of disease, of which the writer has seen one case. It may be associated with concussion or laceration of the cord. It may destroy life directly by extension or indirectly by leading to a spreading inflammation. Hemorrhage in or about the cord causes a gradual compression of the cord, and in cases of fracture of the spine often adds to the compression due to the displacement of the bones. In hemorrhage into the substance of the cord paralysis comes on early or immediately and may be complete while symptoms of irritation fail. The latter symptoms are most marked in meningeal hemorrhage in which paralysis is delayed in appearance and generally incomplete. The products of an inflammation due to an injury may compress the spinal cord in the same way that hemorrhage does.

Wounds and injuries of the varieties we are considering, affecting the spine and spinal cord, are generally accidental, less often homicidal, and almost never suicidal.

WOUNDS OF THE THORAX AND THORACIC ORGANS.

=Wounds of the thorax caused by incising, puncturing, or blunt instruments.= These wounds are most often punctured wounds; contused wounds are common and incised wounds are not rare. They are perhaps most often homicidal in origin or at least inflicted by another, and the accidental origin of these wounds is probably the least common.

Incised or punctured non-penetrating wounds of the thoracic wall are rarely grave. Bleeding, as a rule, is not serious, though it may be quite free. Such wounds may be accompanied by emphysema, though not penetrating, owing to the movements of the chest and a valve-like action of the edges of the wound. Contused wounds of the thorax are more dangerous, especially if the violence was great, owing to the complicating fracture of the ribs, rupture of the thoracic viscera, etc.

FRACTURE OF THE RIBS is a common result of contusions of the chest. It is more dangerous when due to a direct blow or injury, as then the splintering occurs internally and may wound the lungs, heart, or large vessels, while with fracture from indirect violence, from compression of the chest, the splintering of the ribs occurs externally. Fracture of the upper ribs requires more force than that required to fracture the lower ones, and consequently the former is the more dangerous. The diagnosis of fracture of the ribs is generally quite easy by means of crepitus felt or heard, false motion, local tenderness, etc. FRACTURE OF THE STERNUM may be serious if depressed on account of the wounding of the viscera behind it. Devergie[668] cites such a case where the depressed portion of the sternum produced a transverse non-penetrating wound of the heart about an inch in length, which had caused death in thirteen days. Simple fracture of the sternum without displacement of the fragments is rarely serious unless injury of the thoracic viscera is produced by the same violence. Wounds or injuries of the thorax are grave or not according as they penetrate or injure the thoracic viscera or do not do so. A wound may just penetrate the thoracic wall without wounding the thoracic viscera, and is then serious as a rule only when followed by inflammation. In fact, many of the penetrating wounds of the thorax wounding the viscera are only grave on account of consecutive inflammation. We have already seen that various characteristics of wounds of the thorax, especially of stab-wounds, enable us to determine the kind of weapon used, its size, sharpness, etc., and sometimes to identify the weapon itself. In much the same way we can often determine whether the wound was suicidally or homicidally inflicted. The cause of death in wounds of the thorax may be directly due to the wounding of one or more of the thoracic viscera, or it may be due to the inflammation occasioned by it. Wounds of the lower part of the thorax may involve at the same time the thoracic cavity proper and its contained viscera, the diaphragm and the abdomen and its viscera. This is the order in which the different parts would be met with in a wound from behind forward; the order might be the reverse of this in a wound from before backward. Penetrating wounds of the thorax may involve the lungs, heart, or great blood-vessels. Of these, the lungs are most often injured, which is easily accounted for by the greater size of the lungs. In =wounds of the lungs= the immediate danger is from hemorrhage. The hemorrhage appears externally through the wound and from the mouth, being coughed up. Where the lungs are injured by a blow, fall, or crush without external injury, blood appears in the mouth only. The blood coughed up from the lungs is bright red and frothy, and it may also be frothy at the external wound. Hemorrhage from the external wound may be slight, especially if the wound is oblique and acts as a valve. In wounds of the lungs most of the blood may collect in the pleura or in the lungs, and thus, by compression from without or by displacement by the blood within it, prevents air from entering the lungs and produces asphyxia, which may be fatal. More or less dyspnœa usually occurs at first. Emphysema is generally present in the cellular tissues, but this latter symptom may also occur at times with non-penetrating wounds of the chest. If death does not occur speedily from hemorrhage by compression of the lungs or heart, there are good hopes of saving the patient, but the prognosis should be reserved. For even when the first effects of the wound of the lung are survived, the patient may die from the effects of inflammation, recurring hemorrhage, or a too sudden relaxation of regimen. Thus, for instance, if too much food, talking, or exertion are indulged in the case may on this account terminate fatally, and such aggravating causes of death may mitigate the sentence.

=Wounds of the heart= are among the most fatal. Although it was once considered, and is usually thought now by laymen, that wounds of the heart must be necessarily and instantly fatal, the facts are otherwise. If the wound is small and oblique life may be prolonged, and cases are recorded[669] in which wounds of the heart were not directly fatal, and in some of which recovery would have probably resulted if not for other diseases. Cases in which the heart wall was wounded but not penetrated, and in which healing took place, are not very rare.[670] Thus Callender removed a needle from the substance of the heart. But there is perhaps only one case[671] on record in which a wound penetrating the cavities of the heart was recovered from. It is the rule rather than the exception that wounds of the heart, penetrating or not, are not immediately fatal. Thus in a series of twenty-nine cases of penetrating wounds mentioned by Devergie,[672] as collected by Ollivier and Sanson, only two ended fatally within forty-eight hours, the rest in periods ranging from four to twenty-eight days. This delay in the fatal result has been attributed to the arrangement of the muscle fibres crossing one another and tending to close the wound, or at least to make it smaller. As to the various parts of the heart wounded, the right side, especially the ventricle, is most often wounded. Thus out of fifty-four cases of wounds of the heart, Taylor[673] states that the right ventricle was wounded in twenty-nine cases, both ventricles in nine, the right auricle in three, and the left auricle in one case. This greater frequency of wounds of the right side of the heart is easily accounted for by its more exposed position anteriorly, just beneath the chest wall in a part of its extent. The rapidity of death depends largely upon the site and extent of the wound. Lutaud[674] states that out of twenty-four cases of wounds of the right ventricle only two were fatal within forty-eight hours, and out of twelve cases of wounds of the left ventricle three were not immediately fatal. Wounds of the auricles are generally fatal immediately, especially if the cavity is extensively laid open. It is the general opinion that wounds of the auricles are most rapidly fatal, next those of the right ventricle, and lastly those of the left ventricle. This difference is probably due to the comparative thickness of the walls of these parts. Thus the wall of the left ventricle is so thick as to tend to close a wound unless it be extensive. In wounds of the heart death rarely occurs from external hemorrhage, which may be quite slight or even altogether wanting where the wound is due to a crush or fracture of the ribs. Death is usually due to the compression of the heart by the blood in the pericardium. This usually causes syncope, or a slighter pressure may be fatal by causing cerebral or pulmonary anæmia or shock. Death may occur suddenly in this manner or not until after some time. Thus in penetrating stab-wounds little or no blood probably escapes at first, in most cases, but it may ooze or, later on, suddenly burst out into the pericardium. Therefore after a wound of the heart the patient does not, as a rule, die immediately, as formerly and often at the present time erroneously supposed. This fact is of little importance as a rule in surgery, for the patients generally die sooner or later, but it is of importance in medical jurisprudence, for upon it may hang the solution of questions of murder, suicide, or justifiable homicide. It also accounts for the fact that the injured person can exercise voluntary power after the injury. Thus Watson[675] met with a case where a man ran eighteen yards and died six hours after a stab-wound of the right ventricle. The coronary artery was divided and the pericardium was filled with blood. Also Boileau met with an accidental penetrating stab-wound through both ventricles in a soldier who ran two hundred yards, then fell and died in five minutes. A boy admitted to Guy’s Hospital in 1879 lived forty-two hours with a bayonet-wound transfixing the right auricle, the septum, the left ventricle, the mitral valve, and entering the left auricle.

Minute wounds of the chest are sometimes made by needles, etc., in the region of the heart with the intention of killing infants or children. Taylor[676] also mentions the case of a fatal wound of the heart from a needle, the result of accident. We have already cited the case of a needle lodged in the heart wall and removed by Callender by operation. That the puncture of the heart by a small instrument is not necessarily serious is proved by the experiments of Senn,[677] by which he found that “the heart can be punctured with a perfectly aseptic, medium-sized aspirator needle without any great immediate or remote danger.”

In cases of RUPTURE OF THE HEART the question may come up as to whether it was the result of disease or violence. We have already seen that rupture of the heart may occur from falls or crushes without marks of violence to the chest. In general, we may say that in rupture of the heart from violence the right side and base are most often involved, while in rupture from disease the left ventricle is generally ruptured, especially near the apex. The exciting causes of rupture of a diseased heart are often violent emotions or exertion, which may both be present in a quarrel with another and cause rupture without direct violence. The cause need be but slight if the heart is diseased, whether the cause is a natural one or outward violence. Rupture from disease may therefore excite suspicions of murder, but those cases can usually be satisfactorily solved by examination of the organ post mortem. A slight degree of violence may cause rupture of a diseased heart about ready for rupture from natural causes. When a diseased heart ruptures during a quarrel, the symptoms of rupture of the heart may be observed to come on suddenly before and without the infliction of any violence.

=Wounds of Arteries and Veins=, especially within the thorax.—Wounds of large trunks are generally speedily mortal. In the chest we may occasionally meet with wounds of the intercostal or internal mammary vessels or the vena azygos veins. These wounds are often serious and may be fatal. We have already seen that blood in the large cavities of the body, like the chest, is commonly not coagulated, or at least the greater part of it. We have already seen, too, that after wounds of the carotid artery the victim may preserve the power of locomotion for a short time, but not the power of struggling. This fact may be important to help distinguish between murder and suicide. In such wounds of the carotid the voice may be lost, as the trachea is often divided. Death from wounds of large vessels may be due to loss of blood, and if this danger is passed the case may still terminate fatally, as in a case where the brachial was tied for injury and death occurred in three days from gangrene. The wounds of comparatively small vessels may prove fatal from hemorrhage, etc.

In wounds of blood-vessels death may occur from the _entrance of air_ into them. In some cases where this is supposed to have occurred it is quite probable that death was really due to hemorrhage. A considerable quantity of air may enter the circulation, especially the arterial circulation, without a fatal result. When death does occur it is owing (1) to “mechanical over-distention of the right ventricle of the heart and paralysis in the diastole,” or (2) to “asphyxia from obstruction to the pulmonary circulation consequent upon embolism of the pulmonary artery.”[678] Senn found that fatal air embolism could hardly occur spontaneously in a healthy jugular vein, as the walls collapse readily from atmospheric pressure.

=Wounds and Ruptures of the Diaphragm.=—These may be due to weapons, fracture of the ribs, falls or crushes, and disease. They also occur as the result of congenital malformation, though these cases seldom survive long. These injuries are generally homicidal or accidental in origin. As a rule, the viscera are wounded at the same time, or, if not wounded, at least herniated, and may thus become strangulated. It is therefore hard to estimate the danger in such cases, but the prognosis is at all times serious. The most serious cases of such injury to the diaphragm are due to violent contusions or falls when the stomach and intestines are full. The hemorrhage is usually slight, but hernia of one or more of the abdominal viscera usually occurs in such cases, and is said to be more readily produced during inspiration when the fibres are on the stretch. According to Devergie, rupture of the diaphragm with hernia is more common on the left side in the central tendon in front of the crura and at the junction of the left muscular leaflet. Also on either side of the ensiform cartilage and especially on the left side there occurs an area of the diaphragm which may be congenitally weak or even absent, and here too rupture and hernia are likely to occur. _Phrenic_ or _diaphragmatic hernia_ occurs especially after lacerated wounds, even after the wounds have apparently healed. If hernia occurs long after the injury was inflicted, it may be asked whether the wound was the cause of the hernia, and so of death. This can only be determined by examination. Almost any or all of the movable abdominal viscera may be found in a diaphragmatic hernia. It was once supposed that this accident would be immediately fatal, but this is far from the truth. Devergie relates the case where a person lived nine months with the stomach and colon in the chest and died from another cause. Thus a person may have a phrenic hernia and die from another cause, or having had a rupture or wound of the diaphragm he may suddenly acquire a diaphragmatic hernia by reason of a blow or sudden exertion, or the latter may strangulate an existing hernia. A person with a diaphragmatic hernia may have the power of moving or walking, but is more or less incapacitated owing to the compression of the lungs which exists and the consequent dyspnœa, etc.

WOUNDS AND CONTUSED INJURIES OF THE ABDOMINAL WALL AND VISCERA.

Such wounds and injuries of the abdominal wall may be incised, punctured, or due to blunt instruments, etc. They are usually homicidal or accidental, seldom suicidal except in delirious patients or lunatics. The cause of death in such cases may be due to hemorrhage, shock, etc., or to secondary inflammation, which is especially likely to occur in penetrating wounds. The kind of weapon used may often be judged from the nature of the wound. Incised and non-penetrating punctured wounds are usually simple and not grave, but may be otherwise from hemorrhage from the deep epigastric artery, or from inflammation in or between the muscles, or in the subperitoneal connective tissue. In the latter case peritonitis may occur, but is rare. A ventral hernia may, however, result later on, as also from a cicatrix, especially if it is transverse. In such cases the question arises whether the natural results of the wound were aggravated by unskilful or improper treatment or even wilful neglect on the part of the patient or practitioner.

CONTUSIONS of the abdomen are more serious often than those of the chest, for there is less power of resistance. We have already seen that death may occur from a contusion of the abdomen too slight to show a mark of ecchymosis or a serious injury internally. This has been attributed by some to an effect on the solar plexus or reflexly on the cardiac plexus causing a fatal inhibition. Lutaud and others have expressed the doubt whether the cases reported by Travers, Allison, Watson, Cooper, Vibert, and others were carefully examined, and have inferred that some visible organic change must have been present. Some such cases, however, have been examined with especial reference to this point, and no physical injuries and no other cause of death elsewhere has been found. There is no ground, therefore, for a jury to doubt that a contusion of the abdomen was the cause of death because there are no visible marks of injury.

Again, it is a well-known fact that the blows severe enough to cause rupture of the abdominal viscera may sometimes leave no trace of violence in or on the abdominal wall. On the other hand, it must be remembered that effusions of blood may be found post mortem in the sheaths of muscles without indicating violence, so that blood may be found effused in considerable quantity in and around the abdominal muscles without violence having been done. In such cases, therefore, we should note whether abrasions or ecchymoses of the skin are absent or not. If they are absent and there is no other evidence of a blow, the medical witness should hesitate to attribute such an effusion of blood between the muscles to an act of violence.

As in the case of the chest, so wounds of the abdomen are serious, as a rule, mainly as they involve the abdominal viscera. The viscera may be wounded by a penetrating wound or by rupture, and the fatal result is due sometimes to internal hemorrhage or to shock, but generally to secondary septic peritonitis, which may be fatal in a few hours or only after days or weeks. Occasionally wounds of the abdominal viscera undergo spontaneous cure without surgical interference and with or without medical treatment. But as a rule they are fatal unless they receive proper surgical treatment. A wound of the abdominal wall may be penetrating without wounding any of the viscera. Such wounds may be fatal if they are infected, otherwise they usually heal readily and without danger unless they are extensive and the abdominal contents are exposed to the air. The gravity of penetrating wounds varies somewhat with the particular viscus or viscera injured. It is well not to examine wounds of the abdomen by the finger or probe too freely unless a laparotomy is anticipated; for a simple wound or penetrating wound without wounding of the viscera may thus be infected. Enough examination is necessary to diagnose between a simple and a penetrating wound of the abdominal wall.

RUPTURE OR WOUNDS OF THE ABDOMINAL VISCERA.

THE LIVER is most often wounded of any of the abdominal viscera, with the possible exception of the intestines, because of its size, and it is most often ruptured partly because of its size, but mostly owing to its friable consistence. Such injuries most often involve the right lobe, as it is much the larger of the two principal lobes. The anterior surface and inferior border is the most frequent site both of wounds and ruptures of the organ. Ruptures rarely pass entirely through the organ, but are generally not more than an inch or two in depth. They are usually directed antero-posteriorly or obliquely, rarely transversely, and the lacerated granular edges are not much separated as a rule (see Fig. 21). Rupture of the liver may be due to a blow, crush, or fall, or even to sudden muscular action if the organ is large and fatty. Thus Taylor[679] relates the case of a woman who died after child-birth of uræmic convulsions, and in whom there was quite an extensive hemorrhage into the liver beneath its capsule, and apparently due to violent muscular contraction. As we have already seen, the liver may be ruptured without the abdomen showing the marks of external violence. Rupture or wound of the liver is one of the causes of the fatality of wounds and injuries of the abdomen. The fatal result may be and often is due to hemorrhage; in other cases it is due to shock or the occurrence of peritonitis. Wounds of the liver heal readily and hemorrhage is arrested at once, as a rule, by the approximation of the edges. There may be little blood in and about the wound, but it collects in the right iliac region or in the pelvis and is not wholly coagulated. Unless the wound or rupture involves the vena cava, portal vein, or a large branch of either of these, the hemorrhage is apt to be slow and the victim may survive hours or even days, except for active exertion or repeated violence. Two cases illustrating the slowness of the hemorrhage have occurred in Guy’s Hospital. In one[680] the man, showing no urgent symptoms at the time, was sent away, and died a few hours later in a police-station. In this case the liver was ruptured nearly through its thickness, and a basinful of blood had been effused, causing death. In the other case,[681] which occurred to Wilks, the patient survived the accident ten days, and Taylor[682] cites a case which was reported to have ended fatally eight years after the accident. As a rule the injury is fatal, without treatment, within forty-eight hours. Not being immediately fatal as a rule, the victim of a rupture or wound of the liver can walk about, and may be capable of more or less severe muscular exertion after the injury, though the fact of such exertion has sometimes been used by the defence to prove that the rupture was not due to the particular violence in question.

_Wounds and ruptures of the gall-bladder_ result in the effusion of bile. While rupture of the liver is not necessarily followed by peritonitis, rupture of the gall-bladder with the effusion of bile generally causes peritonitis, and is fatal in this way and not from hemorrhage. Rupture of the gall-bladder may be favored by the presence of gall-stones, but the result is still attributable to the injury.

SPLEEN.—Ruptures of the spleen may be due to a bruising violence in this region, and here too the skin may not show the marks of the contusion, though this fact is still employed by the defence to try to disprove the connection between the injury and the result. It is important to remember, from a medico-legal point of view, that an enlarged and softened spleen may be ruptured from a comparatively slight muscular exertion. This might occur in a sudden movement to avoid a blow, and the charge of manslaughter might be affected by the mode of the production of the injury and the previous abnormal condition. Only direct violence is liable to rupture the healthy normal spleen. Rupture and wounds of the spleen may be and generally are fatal from hemorrhage, owing to the vascularity of the organ; more rarely are they fatal from shock. Peritonitis is not a result to be expected.

The hemorrhage accumulates in the lower and left side of the abdomen or in the pelvis, and coagulation is imperfect if present at all.

KIDNEYS.—These are occasionally ruptured from violence, but more often from accident. Wounds of the kidney are rare, owing to the depth from the surface at which they lie. They are more accessible from behind. A wound from behind is generally extra-peritoneal unless it perforates the organ; not so a wound from in front. Accidents in which the lumbar region is forcedly flexed are most apt to be followed by injury to the kidney. The injury may cause no prominent symptoms, but usually lumbar pain and tenderness, frequent micturition and hematuria, and in severe cases the symptoms of hemorrhage and shock are present. The injury may be speedily fatal from hemorrhage or collapse, or more slowly fatal from peritonitis, when the peritoneum is involved, or from abscess and septic infection, or from uræmia if the other kidney is diseased. Slight injuries are generally recovered from. As is the case with the liver and spleen, so after injuries of the kidney the victim may walk about, etc., unless there is copious and immediate hemorrhage.

THE BLADDER may be wounded directly through the hypogastrium, vagina, or rectum; it may be punctured by a broken fragment of the pelvis, especially the pubis, or it may frequently be ruptured from blows, crushes, or falls. The latter accident occurs especially where the bladder is distended. The bladder may also rupture spontaneously from over-distention, which may or may not be favored by disease of the bladder wall, in which case rupture occurs more easily. Medico-legally the question may arise whether the rupture was spontaneous or due to injury. In this connection it should be remembered that the injury may leave no external mark of violence, and a case is recorded in which the bladder was ruptured by a fall in wrestling; but the question can be determined only by an examination of the bladder. If the wall of the bladder is thinned by the pressure of a calculus or from other causes, or if it is weakened by tubercular, syphilitic, or carcinomatous deposits or ulcerations, it may be spontaneously ruptured from slight distention or a slight degree of violence may rupture it. If violence has been employed it is responsible for the rupture, though the diseased condition may act as a mitigating circumstance; not so a distended bladder, as the latter is not abnormal. In spontaneous rupture from over-distention without disease of the bladder wall, stricture, hypertrophied prostate, or some such condition must be present to account for the over-distention. Spontaneous rupture of the bladder can, therefore, only occur when either disease of the bladder wall or obstruction of the urethra is present. No condition excludes rupture from violence. If there is an injury followed by the symptoms of rupture of the bladder and death and the bladder and urethra are healthy, there can be little doubt that death was due to the injury. Wounds or rupture of the bladder may be extra-peritoneal or intra-peritoneal. Rupture from disease of the bladder wall occurs at the site of the diseased and weakened spot, which is most often at the base of the bladder. Rupture of the bladder from violence occurs most often on the postero-superior wall, running downward from the urachus, in which case the peritoneum would be involved. A punctured wound of the bladder wall may be so minute that the leakage is very slow and the customary symptoms may be obscured, or the opening may be valvular in character, perhaps allowing escape of urine only when the bladder is not distended. The _symptoms_ consist of pain, inability to micturate, and the presence of blood in the little fluid which can be drawn by a catheter. Fluid injected is not all returned and the bladder cannot be distended. After a time varying from a few hours to a few days, depending upon the size of the opening and the condition of the urine, peritonitis or peri-vesical cellulitis is set up, the former being generally fatal, the latter not necessarily so. Prompt surgical treatment may save the patient’s life by avoiding peritonitis. Extra-peritoneal ruptures are far less dangerous than intra-peritoneal, as in the former case cellulitis and abscess in the cellular tissue around the bladder, which may subsequently be treated by operation and drainage, take the place of peritonitis in the latter case, for which prevention is the only safe treatment. In extra-peritoneal rupture death, if it occurs, is generally due to septicæmia; in the intra-peritoneal variety it is due to peritonitis. These cases of injury to the bladder may die suddenly and speedily from shock or from peritonitis in three to seven days, or not until fifteen days or so. In punctured and incised wounds the urine escapes more slowly, peritonitis develops less early, and death is longer delayed. Hemorrhage in injury to the bladder is not usually serious; the blood is found partly in the bladder, partly in the pelvis, where the fluid extravasated by peritonitis is also found. The victim of a wound or rupture of the bladder may often walk about for some time after the injury.

STOMACH AND INTESTINES.—Punctured wounds, or, more rarely, incised wounds of the abdomen may involve these organs, or they may be ruptured by blows, crushes, and falls, or from disease. Stab-wounds of these viscera may be multiple from a single stab, the instrument traversing one coil, perhaps, and then wounding others, though this is less often the case than with gunshot wounds. Ruptures too may be multiple, though less often so than wounds. The ileum is most liable to rupture, though several cases of rupture of the jejunum are on record. Like the bladder, the stomach and, to a less extent, the intestines are more liable to be ruptured when distended. Ruptures of the stomach or intestines are seldom attended with much hemorrhage, while wounds may occasionally cause a serious and fatal hemorrhage from the wounding of a large blood-vessel. The principal danger lies in the leakage of the contents of the stomach and intestines, which almost always sets up a septic peritonitis. This may sometimes become localized and go on to spontaneous cure, though as a rule it becomes general and is fatal. In such cases early operation may avoid the fatal peritonitis. A punctured wound may be so small as to be closed by the mucous membrane, avoiding the escape of the contents of the gut. Or a wound may not entirely penetrate the wall of the stomach or intestines, which only gives way some days, perhaps, after the injury, though the injury is entirely responsible for the delayed result. These injuries are sometimes fatal immediately or very speedily from shock, while in other cases of very extensive injury there may be almost no shock, and the victim is aware of no serious injury. It is an important point to remember medico-legally that spontaneous rupture of the stomach or intestines may occur owing to ulceration due to disease. This can be determined by a careful examination of the wall of the stomach or intestines at the site of the rupture. A slight injury may also cause rupture if the wall of the gut is weakened by disease, as the disease causes greater liability to rupture. Here too it is to be remembered that a severe injury causing rupture may leave no mark of violence on the abdominal wall. The power of walking or other muscular exertion after such injuries of the stomach or intestines is not infrequently preserved, as recorded in numerous cases.[683] The prognosis in such injuries of the stomach and intestines is always extremely grave.

INCISED, PUNCTURED, AND CONTUSED WOUNDS OF THE GENITAL ORGANS.

These are not common as medico-legal cases. Self-castration or mutilation is sometimes practised by lunatics, idiots, or even intoxicated persons. Thus a man who, while intoxicated, cut off his genital organs and died the next day from the effects of hemorrhage was seen by Demarquay.[684] Circumcision in infants is also sometimes fatal from phlegmonous inflammation.[685]

Incised, lacerated, or contused wounds of the female genitals may be fatal from hemorrhage from many small vessels. Deeply incised wounds of the female genitals proves wilful and deliberate malice; accident is out of the question and suicide is improbable in such cases. But we sometimes have to determine between accidental, self-inflicted, and homicidal wounds of these parts, as accidental wounds may occasionally resemble those made by design and so may furnish more or less difficulty, unless all the circumstances are known. Thus Taylor[686] relates the case of a child in whom a sharp-pointed stick entered and passed through the posterior wall of the vagina as she fell from a tree. The stick was removed by a woman, and the child died in a little over a day from peritonitis. Unless the circumstances were known, this case might have caused suspicion of homicide.

Lunatics, idiots, and drunkards sometimes inflict on themselves wounds unlike ordinary suicidal ones. In other cases the various points we have enumerated in a previous section to distinguish between suicide, homicide, and accident may be applied to solve the case.

Contused wounds, such as kicks, etc., of the female genitals may be fatal from hemorrhage due to the laceration of the parts.[687] Like the wounds of the eyebrows, contused wounds of the vulva may sometimes resemble incised wounds owing to the sharp bony surfaces beneath. Careful examination allows a discrimination to be made from incised wounds. If hemorrhage occurs a long time after the alleged violence, it is probably due to natural causes, especially in cases of metrorrhagia, etc. It may be alleged in defence that contused wounds of the female genitals were inflicted post mortem, but besides the other features which we have already seen help to distinguish between ante-mortem and post-mortem wounds, we may add that kicks and other contusions of the vulva, if fatal, are so from hemorrhage or effusion of blood, and no post-mortem hemorrhage is enough to cause death.

INCISED, PUNCTURED, AND CONTUSED WOUNDS OF THE EXTREMITIES.

These may be fatal if a large blood vessel or vessels are opened, or sometimes if a compound fracture or wound of a joint becomes infected. They may also in some cases be fatal from shock, from the severity of the injury. As a rule they are the cause of civil suits, not of criminal ones. The various injuries may cause disability for a longer or shorter time, or even permanently, and more or less deformity may also remain. This may be the case with fractures, especially if they occur near the joints, in which case great caution should be exercised in giving an opinion or prognosis. It is a common mistaken idea of the laity that a fractured or dislocated limb can be made in every case as good as before the injury. On the contrary, they not infrequently leave a slight deformity and impairment of function, sometimes even under the best treatment. Dislocations may also leave a lasting disability or weakness, often owing to the carelessness of the injured person.

Wounds of an artery or vein, or both, may result in an aneurism or an arterio-venous aneurism. Wounds of nerves may cause paralysis and anæsthesia of the parts supplied. Wounds of muscles or tendons may cause weakness or complete loss of motion of particular joints. Wounds of the soft parts, if infected, may lead to cellulitis and phlegmonous inflammation, which may result in much injury. Wounds of joints, if penetrating, are serious, for without the proper treatment they may result in suppuration in the joint, disorganization of the joint, and final ankylosis. Before the use of antiseptic treatment such wounds were not uncommonly fatal. Fractures, simple or compound, or contusions of bone especially in young subjects, may be followed by osteo-periostitis and its consequences, which may require a long time for recovery after the fracture is entirely recovered from, and a still longer time before the limb can be used. These and many other of the various results of wounds and injuries of the extremities, causing deformity or disability, or both, can often be cured or improved by surgical treatment or operation.

GUNSHOT WOUNDS.

GENERAL CONSIDERATIONS.

FEW medical men there are who have long engaged in practice who have not been compelled to take part in some medico-legal controversy in cases of accidental or alleged homicidal gunshot wounds. So soon as death occurs the surgeon ceases to work as such, but may continue to work as a medical jurist, and in preparation for this event must be ready to answer any questions bearing upon the case which, though possibly ridiculous in surgery, are or may be necessary in law. He may be called upon to testify as to the precise nature of a wound inflicted upon the body of a man seen before or after death; as to the means by which it was inflicted; whether the purport was suicidal or homicidal; how much blood was lost; whether the weapon was near to or at a distance from the body when fired; whether it were possible that the deceased could have fired it himself; whether after the reception of the wound the person could have moved or performed any act—in other words, whether death was instantaneous. He may be asked also as to genuine or spurious blood-stains, whether genuine blood-stains were human or from some other animal; whether possibly they were from the body of the deceased. He will be expected to tell from what direction the bullet or missile was fired; which the wound of entrance and which of exit, and many other things possible concerning the circumstances under which death occurred. It is unnecessary to state that questions of this nature call not only for conventional surgical skill, but for the highest degree of shrewdness and general information, as well as sometimes for expert knowledge with regard to small-arms and their ballistics.

It has been well said that the first duty of a medical jurist is to cultivate a habit of minute observation. When this is combined with a knowledge of what the law requires and with the results of a technical education, he will be able to meet all or nearly all of the scientific questions which may be asked of him. A learned judge once said that “a medical man when he sees a dead body should notice everything.” Certainly he should make a minute scrutiny of the body to note whether there are upon the dress or hands of the deceased marks of blood, or whether blood-stains are noted in different parts of the room; whether the body or any part of it is cold or warm; whether the limbs are cold or rigid or pliant, since by these means the accurate date of death may be more accurately determined.

EXAMINATION AND DESCRIPTION.

In determining facts attending a suspicious case of gunshot wound, there should be noted, if known, 1st, the exact time of death, as well as of infliction of the wound; 2d, location and attitude of the body; 3d, condition of clothing; 4th, anything of importance in its environment; 5th, external appearance of the body, as well as state of countenance; 6th, exact description of all marks of violence and of blood-stains; 7th, the presence of cadaveric rigidity and the surface upon which cadaver has been lying, as well as its age and condition of general nourishment; 8th, time when deceased was last seen alive or known to have been alive; 9th, time after death at which examination is made; 10th, all physical circumstances corroborating or arousing suspicions of suicide or homicide; 11th, account of an accurate internal post-mortem examination, in which direction of the bullet or missile is noted, along with a careful description of parts disturbed or injured in its course, large vessels or nerves cut across, effusions of blood, and in every way as accurate a description as possible of the exact damage done. To this also should be added a minute scrutiny of other parts, in order to establish clearly that death was due to the alleged injury, or on the other hand that it may have resulted from natural causes, and that the injury in question was only a consecutive and contributing cause. Especially should there be examined those organs in which occur the most common causes of death, namely, the brain, the heart and great blood-vessels, and the viscera. Moreover, if an operation has been performed the post-mortem examiner should be prepared to speak with reasonable positiveness as to whether said operation was, in the first place, necessary if life were to be preserved, and, in the second place, whether death were due to the injury proper or to the attempt to save life thus made necessary. For the determination of all this, obviously the best time for the performance of the examination is the earliest possible moment after death. Nevertheless, bodies are sometimes exhumed for this purpose, and much information is obtainable even after a considerable interval of time.

If death has been caused by a bullet which has not passed through the body, but lodged, it should by all means be obtained, since evidence of the greatest value may inhere in it. Moreover, in first noting the position of the body, the direction of the wound, or the location of a blood-clot upon the floor or clothing or elsewhere, may indicate to the surgeon or other astute person the point at which the bullet may be found concealed or buried in some soft or hard object. This bullet should be recovered, if possible, at all events, although if taken from the body itself the evidence it conveys may possibly weigh more heavily than if removed from some object outside the body. The exact number of gunshot wounds with a minute description and location of each should be committed to paper at once, as well as any statement, if at all reliable, concerning the number of shots fired, since valuable deductions may be reached as to the number of bullets which have passed through or which have lodged within the body. It is well sometimes, also, before dissecting out the bullet-wound, to insert first a stiff and then a flexible probe or something which shall, if possible, follow the bullet-track, since occasionally a question comes up of the direction in which it was fired. Even though surgeons well know that such questions are impossible of satisfactory answer, owing to the manner in which a bullet is diverted in its course by the various tissues of the body, it will nevertheless create a good impression as to the thoroughness and exactness of an examination should it be brought out, in answer to questioning, that this had been done. Many an excellent surgeon has been surprised upon the stand by the question from one of the counsel as to whether he knew that some certain writer had stated that it was always well, in trying to determine the course and direction of a bullet, to put the patient or the body, as the case might be, in the exact position in which it was when the shot was fired, providing this be known. The accomplished surgeon knows that this is a matter of very trifling import, but the witness’ status will be much better established with the jury if he can show himself familiar with this possible method of examination.
