Part 75
In the slighter cases, it is sufficient to restrain the motions of the chest by a broad bandage applied firmly round it; and a split cloth, or a scapulary, may be passed over the shoulders and attached to the circular bandage to prevent its being displaced. Great and immediate relief is thus afforded. In those of a plethoric habit, blood may be taken from the arm, some hours after the injury, with relief and advantage; it may ward off an inflammatory attack—and it is absolutely necessary to adopt this practice on the slightest indication of such supervening. The appearance of the countenance, and the state of the pulse and respiration, must be watched; and on the first becoming anxious, the second strong and accelerated, and the third hurried and imperfect, active measures must be employed—venesection, antimony, purgatives, diaphoretics, anodynes—one or all according to circumstances. In the more severe injuries the same practice is pursued; and the symptoms are watched with great care. The air in the cellular tissue, if effused in great quantity about the neck and face, and interfering with the functions of the parts, is to be evacuated by punctures. If the emphysema is slight, and confined to the neighbourhood of the injured part, farther extrication is prevented by the timely and accurate application of a bandage; the air already in the cellular tissue speedily disappears. The effusion into the chest is also in general absorbed; but it may remain and increase, and from violence of action purulent secretion may be mixed with the serous. The breathing then becomes embarrassed, the chest swells, and the integuments are œdematous. The action of the lung is either much impaired or entirely arrested, as is ascertained by auscultation. In such circumstances, evacuation of the effused fluid may be required.
The _Sternum_ is sometimes fractured, or, in young persons, the bones composing it disjoined; but the occurrence is exceedingly rare. The displacement is not great; and is rectified by changing the position of the trunk. The same treatment is required as for fracture of the ribs. Abscess has formed under the bone, as the result of the injury; but by antiphlogistic means, local and general, this may be in most cases prevented.
_Fracture in the vicinity of the shoulder-joint_ requires to be most accurately examined, that a correct diagnosis may be formed, and the practice be judicious and decided.
Portions of the upper part of the humerus are torn off, along with the attachments of the short muscles, during violent exertions, particularly if the limb is in an awkward position. This is followed by want of power, great swelling, and considerable deformity. Some indistinct crepitation is perceived; the articulation is afterwards stiff, and the bone of an unnatural form. But these indications of the injury gradually disappear.
More extensive solution of the continuity of the bone takes place, generally in consequence of a direct and violent blow on the shoulder. The patient is unable to raise the arm, though with great pain it can be placed in any position that it occupies naturally; it can be abducted and raised, perhaps to a greater extent and more readily than when sound. The shoulder is flattened, and the limb apparently lengthened. The elbow is readily put to the side. On raising the humerus, rotating it, and moving it to and fro, crepitation is distinctly perceived—but not so readily after swelling has taken place. The swelling also obscures the appearances observed immediately after the infliction of the injury,—the flattening of the shoulder, and apparent elongation of the arm. By the fingers of one hand, pressed deep into the axilla, the head of the humerus can be discovered; and, on rotating the shaft of the bone with the other hand, grasping the elbow and pushing upwards at the same time, crepitation is perceived, and the upper portion of the bone is ascertained to be unaffected by the rotation of the shaft. The nature of the injury is then sufficiently apparent.
But the shaft of the humerus may, by such manipulation, be ascertained to be entire. Still, from the direction of the force which effected the injury, the flattening of the shoulder, the remarkable falling down of the arm, the loss of power, the free motion, and from the crepitation, though perhaps indistinct, it is evident that fracture has occurred. Then, by the fingers in the axilla, whilst the humerus is raised and moved in different directions, crepitation is recognised deeper and less distinct than in the former case; and the surgeon is warranted in believing that the glenoid cavity has suffered—that it is broken into fragments, or that it is separated from the body of the scapula by fracture of its neck; he is also warranted in adopting the means of cure suitable to such an accident. Many such injuries are supposed to occur, yet it is strange that preparations illustrative of it are scarcely to be met with in our collections of morbid specimens.
How both detachment and luxation of the head of the humerus should occur, can scarcely be explained. Luxation certainly cannot take place after fracture; no force can be applied to the head of the bone sufficient to displace it. It is barely possible, that after luxation, force may be applied to the bone so as to fracture its neck. This accident is of very rare occurrence, though by some supposed to be otherwise. I have had an opportunity of examining but one case, and that was very distinct; the head of the bone, completely detached from the shaft, lay in the axilla. Comminution of the head of the bone, with displacement of the fragments, is not uncommon.
Separation of the head of the bone occurs occasionally in young persons, presenting the same appearances and symptoms as fracture of the neck of the humerus in later life. Each, by a little care, is distinguishable from dislocation, even after swelling has supervened. And it is highly necessary that the diagnosis should be correct and prompt, otherwise atrociously cruel and unnecessary proceedings will be adopted, and irreparable mischief occasioned. Luxation is attended with flattening of the shoulder and elongation of the arm, to a greater or less degree, according to the position of the head of the bone. But the elbow does not come to the side, and the motions of the limb are abridged; it cannot be abducted to any extent, if the scapula is fixed. The head of the bone is felt under the pectoral muscle, or in the axilla; and on rotating the arm gently, by laying hold of the forearm, and using it, when bent, as a lever, the head and shaft are found to move simultaneously, all of a piece, and no crepitation is felt. Besides, the history of the accident is an excellent guide towards correctly ascertaining the nature of the injury. If the patient, in falling, have involuntarily stretched out his arm, in order to save himself, and alighted with his whole weight on the palm or elbow, dislocation will most probably have occurred. If, on the contrary, he have pitched upon the shoulder, without any intermediate breaking of the fall, fracture is to be expected.
The evil consequences of false diagnosis, and of treatment formed thereon, are very apparent. A dislocation may be put up and treated as a fracture, perhaps till too late for reduction; and the patient will possess but weak and imperfect motion of the limb, after having undergone long suffering. On the contrary, dreadful torments are inflicted on the patient when fracture is treated as luxation. The force applied with the view of reduction is in all circumstances very painful, but, when exerted on a fractured bone, must prove absolute torture; and during the whole treatment, the fragments are, perhaps, every now and then, by renewed attempts, torn separate, and union so prevented. Severe inflammatory action follows the reductive violence, and is kept alive or regenerated by the loose and projecting fractured ends of the bone; extensive suppurations, attended with fever, ensue, and may destroy the patient. Undetected fracture may also be treated as a bruise of the soft parts only; then every motion of the body and limb is productive of excruciating pain, and there is much risk of uncontrollable inflammation being excited—all which would have been warded off, by placing the bones in a proper and steady position in the first instance; the adaptation of a pad in the axilla is followed by immediate and great relief. Such mistakes are quite inexcusable. By one careful examination,—productive no doubt of considerable uneasiness to the patient in some conditions of the parts—the real state of matters should be ascertained; and then the practice founded on the knowledge so obtained will be followed with speedy cessation, or at least great diminution of pain, and with every probability of restoring the limb to strength and usefulness.
Fractures of the glenoid cavity, of the neck of the scapula, and of the neck of the humerus, are all treated by the same simple, though effectual, apparatus as employed for injuries of the clavicle. It requires to be re-adapted occasionally, to have the parts under the crossings of the bandage, and under the knots of the shawl retaining the pad, well protected by soft pads, and it must be worn for four or five weeks—perhaps, in some cases, even a short time longer. Then gentle passive motion of the limb is to be employed, gradually increased as the painful feelings abate. If the parts are at once placed in apposition, and accurately retained, no abstraction of blood, either general or local, is required at the time, and is not likely to be called for during any stage of the treatment. No cold evaporating lotions are necessary; fomentations are sometimes useful.
Fracture of the _shaft of the humerus_ is either oblique or transverse, according to the direction of the force applied. There is considerable displacement. The limb is always shortened to a certain extent, and the natural contour destroyed; the arm is useless, and bent towards the trunk, and the muscles are in a state of spasmodic contraction. The nature of the injury is at once and readily recognised. There is unusual and unnatural mobility of the arm, and distinct crepitation at the fractured point. There is great pain from the pressure of the lower extremity of the bone upon the nervous trunks. The large vessels are seldom torn—though the branches of the humeral artery, and the vessel itself, have in a few cases been ruptured—but there is often considerable bloody swelling in this as in all fractures. Occasionally, when the violence has been great, either the upper or the lower fractured end is thrust through the skin.
When the inferior part of the shaft is broken, there is less displacement than when the fracture is towards the middle of the bone. Fracture above the condyles sometimes extends through them; and the one may be detached from the other either with or without fracture of the shaft. When such an accident is suspected, the position of the condyles in regard to the ends of the bones of the forearm should be accurately observed. Flexion and extension of the forearm can be readily performed, though with pain; not so, when the bones are luxated. Crepitation is detected along the line of fracture, during motion of the limb, and when the condyles are laid hold of and moved upon each other, or on the shaft.
In fracture of the middle of the shaft, coaptation is easily accomplished; slight extension is made by one hand grasping the elbow, whilst, by the other, the bones are brought together, and the straightness and outline of the limb restored. The proper position is readily maintained by two splints of bookbinders’ pasteboard, or of leather prepared for the purpose; one applied from over the acromion process to beyond the point of the elbow, the other from the axilla, and also passing over the elbow on the inside; thus the neighbouring joints are fixed, and the muscles rendered inactive. The conjoined breadth of the splints should be sufficient to embrace the limb almost entirely; some space being left, so that when the swelling subsides, they may neither meet, and consequently lie loose, nor overlap each other. They are softened by steeping in hot water, so that they may embrace every part of the limb to which they are applied; and the extremities should be rounded off, to prevent galling of the parts. They are padded with soft flannel, lint, or cotton wadding, or, what is better, with finely carded tow, and retained by a circular roller applied from the points of the fingers up to the shoulder. The binding should proceed from below upwards, to avoid swelling from obstructed circulation, and do away with the necessity of removing the apparatus arising from this cause. It is well to place a wooden splint on the outside, retained by an additional bandage, so as to steady the parts till the pasteboard or leather has dried, and formed a firm mould or case for the limb; then the wood is no longer necessary, and should be removed. The forearm is bent at right angles, and the humerus fixed to the trunk. In simple fracture, there is in general no necessity for interfering with the apparatus until the bandage slackens, in consequence of the swelling subsiding; then, usually at the end of eight days, it is to be reapplied. One splint is carefully raised, whilst the other is kept fixed and the parts steadied, and the limb is ascertained to be straight and of a proper length; if not, then, or even later, the position of the bones may be rectified without causing much uneasiness. The patient need not be confined to bed on account of a simple fracture; he may walk about with the arm supported in a sling.
In compound fracture similar splints are applied, after due attention has been paid to the wound and to the position of the bones. The patient is placed on his back in bed; and the splints are retained by slips of bandage, double, one end being passed through the loop and secured to the other by a running noose. This method of deligation affords facility for the removal of the splints, in order to examine into the state of the limb and dress the wound. It also permits the apparatus being slackened in the first instance during the swelling, and of being afterwards tightened, without lifting the limb or disturbing its position.
Fracture at the distal extremity of the humerus is managed most conveniently with the limb in the straight position. The fragments are placed accurately together, and one splint placed on the fore part, another posteriorly. The forearm is kept in a state of supination. At the end of about twenty days the apparatus should be removed, and the position of the articulation changed if possible. The forearm is to be bent slightly, and a splint applied,—made to fit accurately, and with a joint corresponding to the bend of the arm. This should be occasionally removed, provided consolidation of the fractured bones has advanced so far as to admit of it, and slight passive motion of the elbow-joint employed. Obstinate rigidity of the parts is thus guarded against.
Fracture of the condyles has been already alluded to. It may be farther observed, that the exact nature of the accident is often difficult to detect; in all cases accurate and careful manipulation is required. Displacement of one or other of the bones of the forearm almost uniformly attends this fracture, sometimes rendering diagnosis obscure.
Fracture of the _olecranon_ process of the ulna is occasioned by falls on the point of the elbow; or the bone may be snapped asunder by powerful and sudden action of the triceps extensor cubiti, when the arm is much and quickly bent. The injury is readily recognised; there is inability to extend the forearm by its own muscular powers, a considerable space is felt between the separated portions of the bone, and the upper fragment is moveable as well as detached; these marks of the injury are rendered more conspicuous by bending the joint. Crepitation is produced by moving the limb when extended, and the separated parts thereby approximated. Bloody swelling soon takes place, large and extensive when bruising of the soft parts has been great—and this is usually the case, in consequence of the injury being almost always the result of direct violence. In some cases the process is comminuted.
Compound fracture is rare, and likely to be productive of serious consequences. I have treated and witnessed several cases. In one the process was cut off by the patient falling out of bed on an earthenware vessel, which broke under the limb. The joint is necessarily opened. Violent inflammation soon commences, and can very seldom be kept within moderate bounds. Discharge of increased and vitiated synovial secretion takes place, followed by profuse and unhealthy suppuration. The cartilages ulcerate, and then the bones. The cellular tissue around becomes infiltrated, the parts swell and are discoloured, and collections of matter form probably at more points than one; perhaps there is a succession of abscesses. The condyles, and often a portion of the shaft of the bone, are denuded by the suppuration, and superficial necrosis results. Ultimately the patient grows hectic. Amputation had to be resorted to in three of the cases which have come under my observation, at the end of some weeks or months from the receipt of the accident.
Union of the simple fracture will take place by bone, if the portions be retained accurately and permanently in contact; but there is a risk of the joint remaining stiff, and of re-separation being produced by even slight violence. Union by ligament is as rapid as that by osseous matter; and if the ligament is short, the arm is quite as useful. Approximation of the broken surfaces is favoured by extension of the elbow-joint, the triceps muscle being thus relaxed. The limb must not, however, be but perfectly straight. The position is preserved by a splint placed on the fore part of the limb, extending from the middle of the arm to the lower part of the forearm, and retained by a roller applied, not over-tight, from the fingers upwards. The application of apparatus to the separated portion, with the view of forcing it into contact with the shaft of the ulna, is useless. The figure of 8 bandage, and such like, are hurtful. Permanent relaxation of the triceps, with prevention of motion, is sufficient. This is continued for three or four weeks; by that time the fracture will in all probability have united, and then gentle and gradual passive motion of the joint is to be commenced.
In compound fracture the prognosis is always unfavourable. Means must be taken to avert incited action—the limb must be properly placed without delay, the edges of the wound accurately approximated, and antiphlogistic measures pursued. Purulent collections must be opened early. Rest of the joint is to be insured, and support afforded, by bandaging and by the application of a splint. The patient will be fortunate if he escape mutilation by the amputating knife; but when the wound is trifling, and the parts not much lacerated or bruised, and the treatment carefully conducted, a cure may be effected by the same process as the simple fracture.
Fractures of the bones of the _forearm_, of one or both, are common; generally simple. The _Radius_ may be broken at various points—at the upper part—near its head—at the middle—most frequently near the distal extremity. At the two first points the fracture will probably have been produced by direct violence; but near the carpus, it is usually the result of force applied to its extremity, as by falls in which the weight of the body is thrown on the palm of the hand. The _ulna_ is usually broken by force directly applied, as when the arm is brought in contact with hard bodies in falls. By direct violence also, both bones may give way about the middle, and at corresponding points: or, when force is applied in the direction of the bones, the ulna may be found broken near the wrist, and the radius near the elbow.
When one bone is broken, there is little displacement. The power of motion is lost to a considerable degree, and there is some deformity, but little or no shortening. The existence of fracture is ascertained by tracing the bones with the fingers, and by gently rotating the limb; the broken portions moving on each other produce distinct crepitation. When the radius is broken near its middle, the forearm is kept pronated, and the broken extremities are drawn towards the ulna; by bringing the limb towards the supine position, the ends come together, and the one bone is removed from the other. Fracture of the radius near or through its distal extremity produces displacement of the wrist, with great deformity; and this is increased by bloody effusion into the sheaths of the tendons, and into the superficial cellular tissue. In fracture of both bones, there is much deformity and shortening of the limb; the power of moving the hand is lost; the muscles are bruised and torn, and great swelling soon results.
There is little difficulty in remedying the slight displacement which takes place when but one bone is broken, and in retaining the parts in a favourable position. In children, occasionally, one of the bones of the forearm is broken, the other being bent very considerably, so as to cause great deformity.[62] When both have given way, slight extension is required, and the forearm is placed in the middle state between pronation and supination. Two pasteboard splints, softened in hot water, and padded with tow, are applied, one on each aspect, from a little above the elbow to over the fingers; the outer should extend to the tips of the fingers, the inner need not pass the palm; they are retained by a roller. In fracture of both bones, a wooden splint should be retained on the outside of the limb for a few hours; but this precaution is scarcely required when but one has suffered. Similar treatment, along with attention to the wound, is required in compound fracture.
The _metacarpal bones_ and _phalanges_ of the _fingers_ are subject to fractures, both simple and compound. The metacarpal bone supporting the little finger most frequently suffers from force applied to the knuckle, as in pugilistic encounters. The other metacarpal bones are occasionally broken from crushing of the hand, as by a heavy body falling on it, or by its becoming entangled amongst machinery. The injury is readily ascertained by moving the fingers, and pressing in the course of the bone. On laying hold of the distal end of the bone suspected to have given way, placing the fingers over the shaft, and attempting slight motion, distinct crepitation is perceived. For the cure, motion of the parts must be prevented for a sufficient time, and inflammation warded off when threatened; there is a little or no displacement, and consequently retentive apparatus can be almost wholly dispensed with.
Simple fractures of the phalanges are recognised and treated by even the most unlearned in the surgical profession. The deformity is so striking as to render mistakes as to the nature of the accident impossible; reduction is accomplished without difficulty; and the bones are kept in their proper places by a small splint, either of wood or pasteboard, placed on each side of the finger, and retained by a narrow roller fixed by glue or starch.
Compound fractures of the phalanges are almost uniformly followed by most violent inflammatory action in all the tissues, terminating in disease of the joints, and in death of the tendinous and fibrous tissues. The suppuration is profuse and unhealthy, and the infiltration of the soft parts extensive. The diseased action not unfrequently pervades the palm of the hand. In the great majority of cases, necessity for amputation arrives sooner or later.
