Elements of Surgery

by Robert Liston

It has been proposed to excise the head of the fibula after formation of the flap, instead of sawing it across at a corresponding point with the tibia. At one time I put this modification into extensive practice, with the effect of improving the appearance of the stump very considerably; but in several cases, untoward consequences took place. Discharge of synovia occurred on the second day, followed by very profuse suppuration, which proved of long continuance, and very exhausting; in more than one case, the joint became anchylosed, rendering the stump very inefficient as a means of support, in consequence of being fixed at an inconvenient angle; and one patient sank, exhausted by the profusion of the discharge. I then found, from repeated examination of the parts on the dead subject, that it was very difficult, nay impossible, to excise the head of the bone without dividing the capsular ligament, and wounding the synovial pouch, or opening a bursal cavity, beneath the popliteus muscle, communicating with that of the knee-joint. It is scarcely necessary to add, I have since wholly abandoned this method of operation.

It has been already observed that high amputation of the leg is preferable amongst the working classes. The limb is of much greater use to the patient than were the stump longer; he is able to follow his occupation with greater ease and security, and at less expense, by resting on the knee, than by using the artificial limb applied to the middle of the leg. The wealthier patient, however, can afford a more expensive support, and a less efficient, though more handsome continuation of the limb suffices. In such circumstances, amputation is performed at the middle of the leg; after cicatrisation, the artist supplies an artificial support resembling the natural limb; and thus the motion of the knee is preserved. The same directions apply to this operation as to that immediately below the knee.

In amputation of the thigh, the same method of incision is followed as in amputation of the arm. But, according to the point of removal, the direction of the flaps varies. If in operating high in the limb the flaps be made laterally, there will be imminent risk of the bone protruding through the upper part of the wound; for the patient uniformly raises the stump towards his abdomen. No antagonist muscular power is left to oppose the action of the muscles inserted into the trochanter minor, and the elevation of the stump is involuntary: it always occurs to a remarkable extent in young persons. On this account, anterior and posterior flaps are here far preferable to the lateral; for then the more the stump is raised, the better is the end of the bone covered—the anterior flap folds over it. Transfixion is therefore made horizontally; and the posterior flap should be a little longer than the anterior. But in the lower part of the limb, lateral flaps are not only not liable to the same objection, but preferable to the anterior and posterior. In the neighbourhood of the knee-joint, the soft parts consist almost entirely of ligamentous tissue on the fore and back part, and proper cushions can be obtained only from the sides. Transfixion is therefore made perpendicularly. Thus the bone will be well covered by parts likely soon to adhere; and there is no risk of protrusion, for muscles are left to counteract the elevators, and there is sufficient lever in the limb whereby to control its motions. And it may be here mentioned, that after all amputations, when startings of the muscles are not only painful, but disturb the position of the stump, the limb should be bound down by a broad band, passed across it a short way above the wound, and fastened firmly at each end to the bed or pillow; at the same time anodynes are to be administered. I have long since come to the conclusion that the femur in amputation should not be sawn lower than its middle; the method by anterior and posterior flap is therefore the only one applicable.

Amputation at the hip-joint is deservedly ranked amongst the most formidable operations in surgery. It ought, therefore, never to be performed but as a last and necessitous resource for the salvation of life. At the same time, when necessity for it is obvious and acknowledged, and no other means can be of any avail, hesitation and delay should never take place; otherwise the last and only chance of saving the patient will pass away, and the operation, when at length performed, will but hasten his exit from this world,—and besides inflict an injury to science, by intimidating practitioners, and affording subject of reproach and ridicule to the thoughtless and uninformed part of the public. I prefer the formation of anterior and posterior flaps,—as follows:—The patient is placed recumbent on a firm table, his nates resting on, or rather projecting a little over, the front edge. The sound limb is separated from the one to be removed, and held aside by an assistant. Or it is secured to the foot of the table by a towel, the necessity for an additional assistant being thus done away with, and more freedom in his movements afforded to the operator. Indeed, in all amputations of the lower extremity, this is the preferable method of fixing the sound limb. The other limb is supported by an experienced and intelligent assistant, who understands, and is able to perform, the movements to facilitate the different steps of the operation. The compression is intrusted also to an experienced and steady assistant, who, standing by the patient’s side, presses firmly with one or both thumbs on the femoral artery, where it passes over the pubes; and in this more than in any other operation should the pressure be delayed till the instant of incision, for otherwise the blood lost in the limb will be immense. Transfixion, by a knife proportioned in size to the dimensions of the limb, is made horizontally, the instrument being passed in a somewhat semicircular direction, so as to include as much of the soft parts as possible; an anterior flap is made by cutting downwards. During the passage of the knife across the joint, the assistant rotates the limb a little, so as to facilitate the bringing of the instrument out with its point well inwards; in the left limb the rotation will be inwards, in the right outwards. After formation of the flap, the assistant abducts forcibly, and presses downwards; the joint is opened, the round ligament cut, the capsule divided, and the blade of the knife placed behind the head of the bone and the large trochanter; the posterior flap is then made rapidly. After transfixion for the superior flap, and when the sawing motion downwards has advanced but a little way, the compressing assistant shifts one of his hands into the incision, immediately behind the back of the knife, and so obtains a firm grasp of the femoral artery previously to its division. He retains this hold, at the same time retracting the flap, during the rest of the operation. As soon as the limb has been separated, the surgeon secures the vessels on the posterior flap, partly by his fingers, partly by compression with a large sponge, and ligatures are applied as quickly as possible. The femoral is secured last; for, as long as the assistant retains his hold, hemorrhage from it is not to be dreaded. Thus, when both surgeon and assistants are quick and cool, the operation may be completed with the loss of much less blood than might be expected. I have had occasion more than once to perform this operation, and thus speak from experience. In cases of accidental injury requiring this operation, the lever use of the limb must frequently be wanting; and in such cases, too, the parts may be so injured as not to afford flaps anteriorly and posteriorly. In these circumstances, the surgeon must be guided by experience and judgment in adopting the mode of procedure which appears most applicable; in ordinary cases the operation above detailed appears the preferable.

Excision of diseased portions of bones, is practised occasionally with the view of removing a source of irritation and exhaustion from the system, without sacrifice of a limb. When the operation proves successful, the beneficial effect on the general health is as remarkable and rapid as after removal of the hectic cause by amputation; the pulse falls and grows firmer, diarrhœa and sweating cease, the hectic flush leave the cheek; in short, the constitution makes a complete and successful rally. It is had recourse to in order to take away disease in the following situations,—in the cancellated articulating extremity of a long bone, in part or the whole of a short bone, and in part or the whole of long bones. Even a long bone, from one articulating surface to the other, may be removed; the metacarpal bone of the thumb, and the metatarsal bone supporting the great toe, may, for example, be taken away in their whole extent. I have seen these bones so treated, but the result was unsatisfactory. As has already been observed, the part of the member that is left is without support, and not under the influence of muscle; it is consequently loose and useless.

Operation for the removal of necrosed, or softened and ulcerated portions of the carpal and tarsal bones, is sometimes successful. But operative interference, either with these, or with more extensive and formidable articulations, is not advisable unless the soft parts are not largely involved, and when the general health is tolerably good—the patient either having suffered less than usual, or having rallied and begun to gain strength after exhaustion by discharge and fever. If the ligaments, bursæ, and cellular tissue are much affected, as is often the case, there is no chance of discharge ceasing, and the patient regaining health, even though the bone be removed to any extent—a second operation will be required, namely, amputation above the diseased parts. And when this becomes requisite, after failure of the first to restore or even improve the health, the patient is apt, as has too often been the case, to sink under the accumulation of suffering. He might, even though much exhausted, have been able to bear up against the shock of one and a successful operation, but he cannot endure that of a second, or perhaps third, serious and protracted attack of the knivesman. The disappointed hope of a cure from the first operation is a secondary, though nevertheless a sure contributor towards the unfortunate issue.

No particular rules can be laid down for the operative procedure. By converting two or more natural openings into one, extending the incisions as much as possible in the direction of the limb and of the muscles and tendons, and avoiding the course of the larger bloodvessels and nerves, room is made for an accurate examination of the diseased parts. A strong and firmly pointed knife is required for these incisions, for the soft parts are much consolidated, and are cut with difficulty. The extent of disease is ascertained both by the probe and by the finger, and farther measures, if necessary, are then adopted for complete removal. Loose portions of bone are taken away; and often large sequestra of the cancellated tissue are found lying in the cavity, either loose or easily separable; for extraction, forceps and the fingers, and sometimes a lever, are required. A firm scoop is useful for removing such portions of diseased cancellated tissue as are still continuous with the shaft of the bone. When an opening in the cancellated tissue, leading to an internal sequestrum, is minute, enlargement is effected by means of either the trephine or the cutting pliers: afterwards, gouges, gravers, &c., may sometimes be useful in operating on the soft texture underneath,—but they are seldom requisite. The bleeding from the soft parts is free; the vessels do not retract, and may require the application of a needle and ligature. That from the bone is easily arrested by pressure: the cavity is filled with charpie or with dossils of lint, and these are supported by a bandage. Some days after, this dressing is removed, having been previously softened and loosened by fomentation and poultice. The cavity should now be examined carefully, to ascertain whether or not all the diseased parts have been taken away; it is then dressed daily from the bottom. If parts of the surface assume an unhealthy aspect, the granulations being either backward or flabby, to these escharotics should be applied—the most suitable is the red oxide of mercury. Gradually the cavity fills up, and a depressed, firm, and permanent cicatrix is obtained. It need not excite surprise, however, if, in not a few cases, after matters have proceeded apparently very favourably for some time, the surface become pale, soft, and glistening; the discharge thin, acrid, and profuse; the integuments around tumid and discoloured,—if, in short, the disease be in no long time fully reëstablished.

The tarsal and carpal bones are often the subjects of this operation. In a few cases I have removed several, in others one or a portion of one, with success. In one instance the greater part of the astragalus was taken away, along with the ends of the tibia and fibula. There remained, in consequence, a large opening across the joint, through which a cord was passed, to facilitate gradual and piecemeal discharge of remaining portions of diseased bone. The articulation could actually be seen through. The seton was gradually diminished and the aperture closed. The foot was thus preserved, and the leg was but little shortened; the limb proved strong and extremely useful, but the ankle-joint retained little or no power of motion. I have also again and again trephined the os calcis, and removed large portions of it; the cuboid likewise has been taken away, along with the base of the metatarsal bone or bones in connection with it; in some of these cases an excellent cure followed, in others amputation of the foot was afterwards necessary.

Some have ventured to cut away the articulating ends of the bones composing the knee-joint. This may be accomplished without much difficulty. The patella is either removed entirely or turned to a side, the ligamentous and tendinous attachments are divided, and the ends of the bones thus exposed; by cutting close to and towards them, little risk is incurred of wounding the bloodvessels and nerves in the popliteal space. The saw is readily applied in a horizontal direction. After tying the vessels, and approximating the edges of the wound, the limb is placed in the straight position, and retained fixedly so by the application of splints. Much constitutional disturbance is to be expected, as well as profuse and tedious suppuration. There are few surgeons so rash as to have recourse to this operation. One or two patients, it is true, have lived in spite of it, retaining the limb in a tolerably useful state. But in others,—and these constitute the majority,—amputation was after all required, and that proved insufficient to save the patient. In short, the results of excision of the knee-joint do not justify its repetition.

The articulating ends of the bones composing the shoulder-joint have been removed; and this may be done with advantage on account either of disease or of injury. This joint is, like others, liable to ulceration of the cartilages, either primary, or in consequence of abscess and degeneration of the soft parts around. The disease is attended usually with painful feelings increased by motion, and the patient is indisposed to attempt motion. Sometimes merely weakness of the limb is complained of, and the attention is drawn to the wasted appearance of the muscles, particularly of the upper arm; the deltoid seems shrunk almost to nothing. The motions above the shoulder are lost; and abduction is impracticable. Much pain is produced by pushing sharply the articulating surfaces into contact, and is further increased by rotation. The enforcement of strict and absolute rest of the joint, the establishment of a drain in the soft parts immediately neighbouring, and attention to the general health, often prove sufficient to arrest the progress of this disease. If, however, it is neglected, abscess forms sooner or later. On cutting into this, and introducing the finger, the joint is discovered to be open; the head of the bone is found detached from the soft parts, and unsupported. Or this state of parts may be ascertained to exist by examination through a sinus, either with a probe, or with the finger after dilatation. In these circumstances, an attempt may be made to check disease, and preserve the arm, by excision of the obnoxious parts of the bone. And this kind of operation is also justifiable when the head of the humerus has been shattered by musket-shot; or when it has been exposed and injured by a splinter, or by a large shot, and the joint laid open. The situation and course of the incisions will be so far regulated by the openings or wounds already existing. They should always be made in the direction of the fibres of the deltoid, and the posterior aspect of the articulation is preferable to the anterior. One incision, from the back of the acromion process to near the insertion of the muscle, is sufficient to expose the head of the bone, to allow all its remaining attachments to be separated, and to admit of its being turned out so as to be conveniently acted on by the saw. The head of the bone merely is taken away. In separating the soft parts from its neck, the edge of the knife should be always directed to the bone, to avoid the nerves and vessels on the inside. In some cases of injury, very little additional wound may be requisite. The glenoid cavity may, in consequence of being seriously involved in disease, also require removal; this is best accomplished by large cross-cutting pliers. Few vessels require ligature. The edges of the wound are brought together; the elbow is supported, and the arm fixed to the trunk, in order to keep the bones in apposition, and prevent motion. This position must be retained during the rest of the cure; and when the wound is on the outside of the shoulder, as recommended, the dressing of it does not interfere with the retentive apparatus. The discharge gradually ceases, and cicatrisation is obtained, though not till after a considerable time, at least in general. The cut ends of the bones accommodate themselves to each other, and a sort of new joint is formed—but never strong. The motions of the forearm are perfect, though perhaps weakened; those of the upper arm are very incomplete. I have both performed and assisted in the operation repeatedly, and never experienced any difficulty; a cure has not always followed, but in some cases the limb has become very useful.
