Part 23

27. Hence it follows, that the operation we are considering, when skilfully performed, never gives rise to any dangerous or disagreeable affections. Experience has proved the truth of this assertion in the practice of Theden, Simson, Gooch, Broomfield, Bell, and Desault, the latter of whom performed the operation five times with complete success. The only case in which he was less fortunate, was that of a man, in whom the wound of the integuments closed up at first without any accident, but which was succeeded by two abscesses, one in the thigh, and the other in the leg, but without any affection of the interior of the joint. This patient was subject to a wandering rheumatism, which oftentimes attacked the lower extremities, and was perhaps in the present case the chief cause of the unfavourable occurrences.

28. It is to the English that we are indebted for the first operation performed for the extraction of these bodies. An account of this is given in the Transactions of a society in Edinburgh. Since that, the operation has been frequently repeated, and more than ten instances of it were already on record, when Desault first performed it in France. His method, somewhat different from that of others, was as follows.

1st, The patient must be laid on a bed, or seated on a high chair. The first position, however, is to be preferred, because when it is adopted, the patient need not be moved after the operation.

2dly, The leg is extended on the thigh, in order to relax the anterior part of the capsule of the joint.

3dly, The surgeon then searches for the foreign body, moves it to the internal side of the joint, against the attachment of the capsule, and secures it between his thumb and the fore-finger of his left hand, while an assistant draws the skin over the fore part of the rotula.

4thly, Taking then a common bistoury, he makes, on the protuberance formed by the body, a longitudinal incision of an extent proportioned to its size, through both the integuments and the capsule, so as to lay the body bare at the first stroke.

5thly, Sometimes the body escapes immediately of its own accord, in consequence of the compression made on it by the fingers. If its passage out be not spontaneous, a small scoop or a taper-pointed spatula passed under it, answers the purpose of extracting it. But, in the introduction of these instruments, it is necessary to avoid touching the articulating surfaces with their ends, lest, by being irritated, they might swell, and give rise to troublesome accidents.

6. If any resistance be met with, enlarge the opening and the extraction will become easy. Without this precaution, the edges of the wound, being bruised and irritated by the passage of the body, will swell, inflame, and unite again with difficulty.

7. When the extraction is finished, the assistant who draws the skin towards the inside of the joint, suddenly lets it go, when it returns to its natural situation. This causes the two incisions, which corresponded, at the time of the operation, to change their relative situation, the one remaining internal and the other becoming external.

8. Hence arises a twofold advantage; the entrance of air into the interior of the joint is prevented, and the external and loose portion of the capsule, being drawn inwards with the skin, unites with the condyl, if it be not brought into exact apposition with the other portion of the capsule, divided near its attachment.

9. The extraction being finished, it is then necessary to examine carefully, in order to ascertain whether or not the joint contain any more of these foreign bodies. On some occasions, when this is even the case, they cannot at the time be discovered. Desault himself was once deceived on this score, in consequence of which his patient was obliged to submit to a second operation.

10. The incision in the integuments is now united by means of adhesive plaster. Over this are laid compresses and a little lint, and the whole secured by a few turns of a roller drawn moderately tight.

11. The leg being then placed on a pillow, is kept in a state of extension, by means of a splint applied, for a few days, behind the joint.

29. If we examine but for a moment the process in this operation, we must perceive, that an incision made through the skin and capsule at a single stroke, is, in no respect, less advantageous than one made at two strokes, as recommended by all practitioners, and that, it is in the following respects greatly preferable to it: 1st, it shortens the operation very considerably: 2dly, it diminishes the pain: 3dly, it exposes the joint a much shorter time to the contact of the air.

30. The object of the operator is better answered by drawing the skin outward and towards the rotula, than by either depressing it, as Broomfield did, or raising it, as Bell does. Being more loose and more easily stretched in this direction, the opening in it is removed farther from that in the capsule, which prevents more certainly the access of air to the joint, and also favours the examination of the capsule.

31. In the mean time, the operation may succeed, even although the openings in the integuments and the capsule correspond to each other. Many English and German practitioners, without previously stretching and changing the natural situation of the skin, make a common incision, which they dress afterwards like a simple wound, and are yet no less successful than others in the result of their operations. This is a further proof of the fallacy of the ancient surgical doctrine, respecting the admission of air into the cavities of joints. Perhaps Desault might have omitted this precaution, had any operations of the kind occurred in his practice during the last years of his life.

32. The operation is seldom attended with much pain. Only one patient manifested signs of this in the practice of Desault. Nor have those operations of the kind performed in England been more painful, so that it may be laid down as a principle, that in most cases no primitive accident is to be dreaded.

33. With regard to hemorrhagy, as there is no large artery near the place of the incision, there is nothing to be apprehended on that score. Oftentimes there is scarcely any loss of blood at all, as may be seen in the first case published in the Journal of Surgery. But, even admitting that a small articular branch be divided, the reunion of the edges of the wound will be sufficient to check the hemorrhagy, in the same manner as in the operation for the hare-lip, the contact of the divided integuments of the lip, puts an end to the hemorrhagy from the small arteries of the part.

§ XIV.

OF THE SUBSEQUENT TREATMENT.

34. I have already said that but little is to be apprehended on the score of accidents subsequent to the operation (26). Out of the numerous operations of the kind performed lately in Europe, but few cases have proved troublesome in their consequences, and even these were influenced by some foreign circumstances. Thus, for example, one of the patients of Simson rode out on horseback a few hours after the operation, on a cold and stormy day, and thus produced a troublesome affection of the part. A similar remark may be made respecting the case formerly mentioned (27).

35. The apparatus or dressing remains untouched for the two or three first days, during which time it is necessary to wet it frequently with vegeto-mineral water. It is a certain truth, that the use of this liquid retards the suppuration of wounds, and that, when continued a due length of time, it keeps inflammation at that degree most proper for the process of healing.

36. On the removal of the dressing, the wound is sometimes so perfectly healed up, as not to exhibit the least discharge. At other times a slight suppuration takes place; but, at the end of a few days, the cure is complete. Under the care of Desault, it was always effected in eight or ten days.

37. Let us bring the doctrine just laid down to the test of experience. Five cases have been published on this point. I have selected two of them, both which occurred in the same subject, where we find the same operation twice performed with equal success.

CASE I. M. Vielle, aged nineteen, was attacked about the beginning of the year 1790, by a spontaneous swelling in the joint of the knee. Inconsiderable at first, but increased afterwards by a laborious journey, it disappeared at the end of two months, discovering to the touch, near the internal edge of the rotula, a foreign body, which was hard and moveable, and which somewhat impeded the motions of the joint.

About a month afterwards, the swelling returned, and, having continued for three months, disappeared again, when the body was found at the external side of the rotula, increased in size. Sundry external applications were tried for six months without success.

Weary of this unavailing practice, the patient came, in March, 1791, to consult Desault, who discovered a cartilaginous substance of a flat and circular figure. Its usual situation was at the external side of the joint, but it could be easily moved to the internal side, and could be turned on its own axis within the joint, nor did it occasion any pain, when suffered to remain at rest by the side of the rotula. But, when it passed behind the tendon of the extensor muscles, the patient was unable to stand, and he experienced severe pains when it made its way under the condyls or behind the rotula.

The indication was evident. Before the operation Desault prepared the patient by a proper regimen, and then, in the method already described (28), extracted a foreign body, whitish, and oval, fourteen lines in length, ten in breadth, and two and a half in thickness at its middle. It consisted of three pieces, united by a ligamentous substance, and was smooth on the side next the joint, but rough with irregular tubercles on the opposite side, and on its circumference. There was no loss of blood during the operation: the usual dressing was applied, after the most attentive examination, as to the existence of a second body.

Neither pain nor swelling supervened, and by the fourth day, the reunion was complete. In a short time motion was performed with as much ease as before the occurrence of the complaint. In the mean while, a degree of uneasiness remained in the joint; but barely perceptible at first, this uneasiness continued to increase; in about four months, symptoms of the existence of another foreign body made their appearance.

M. Vielle being now a distance from Desault, put himself under the care of his brother, who extracted a second body, in the manner already described, except that the incision was made at two strokes.

Dressing the same as in the preceding case, with this additional precaution, that the thigh and leg were covered by a roller, for the purpose of moderating the action of the muscles.

No fever, no pain; the reunion completed on the eighth day, except a small point in the centre of the wound, which suppurated slightly till the fourteenth. There was now neither difficulty in walking, nor the least sensation of pain. Since that time, M. Vielle has enjoyed the entire use of his limb.

OBSERVATIONS AND REFLECTIONS

ON FORMS OF APPARATUS FOR FRACTURES OF THE LEG.

§ I.

1. CASE I. (Reported by Levacher). Catharine Belet, aged fifty-five, of a strong and vigorous constitution, fractured her leg in the middle, by a false step in alighting from a carriage. Being carried home, in a careless manner, she was visited by a surgeon, who merely reducing the fracture, but applying nothing to retain the reduction, sent the patient to the Hotel-Dieu. She was conveyed on the same day to the amphitheatre, where Desault discovered the existence of the affection by the following signs.

Pain in the middle of the leg, less severe when the limb was at rest, more so when it was suddenly moved; the patient absolutely unable to support herself on it so as either to stand or walk since the accident; inequalities sensible to the touch on the anterior surface of the tibia; a shortening or contraction of about half an inch; a preternatural mobility at the place of the fracture; evident crepitation, produced by the rubbing of the fragments against each other, when moved in contrary directions: a change in the direction of the lower fragment, which was bent somewhat outwards. These signs, added to the circumstance of the fall, evidently announced a simple fracture of both bones. The reduction was effected in the following manner.

One assistant made counter-extension by grasping the lower part of the thigh with both his hands, the fingers being placed behind it, and his thumbs corresponding to its anterior surface. Another made extension, not as writers recommend, at the lower part of the leg, but on the foot itself, which was taken hold of in such a manner that the fingers met on its upper side, while the thumbs crossed each other on its sole. In this way a lever of the first kind was formed, the resistance to which was the fragment to be replaced, while its centre of motion was in the joint.

Extension being directed at first in the course or line of the displacement, till the limb had attained its usual length, was then directed in such a way as to restore to the leg its natural form. By this, the fragments being brought into apposition, united exactly without the process of coaptation being employed.[34] The apparatus, usually employed by Desault in such cases, was applied to maintain the reduction: the different pieces of it had been previously arranged on a pillow in the following order: 1st, four strong pieces of tape placed at equal distances from each other; 2dly, a junk-cloth,[35] long enough to reach from the knee beyond the sole of the foot; 3dly, a bandage of strips, similar to that described for the thigh (page 246), arranged in the usual mode; 4thly, two long compresses, the lower one of which being the longest was turned back on the other; three bolsters had also been prepared; these, being formed of several pieces of linen joined together, were about one inch and a half thick: the broadest of these was designed to be placed on the anterior part of the leg; the two other lateral ones, though narrower, were a little longer, in order that, by folding back on themselves, they might be accommodated to the inequalities of the limb; 6thly, lastly, there were also prepared two splints, an inch broad, three lines thick, and of the same length with the junk-cloth.

[34] That is, without any assistance from the hands of the surgeon. TRANS.

[35] Analogous in its form and uses to that employed in fractures of the thigh. It may not be amiss, on this occasion to mention, that in the form of apparatus for oblique fractures of the leg, represented in the Appendix, plate III. no junk-cloth is necessary. TRANS.

Every thing being ready, the assistants still keeping up extension raised the leg a little, while a pillow was slipped under it, to support it equally and uniformly throughout its whole length. The leg was placed on this pillow in such a way as to correspond exactly to the middle of the apparatus which was arranged in order on it, and was previously wet with vegeto-mineral water.

On the anterior part of the leg was then applied a long compress, extending from the knee to the upper part of the foot. Over this were lapped the other two compresses, which had been previously placed in order as part of the apparatus. These were then secured by the bandage of strips, the application of which was begun at the lower strip next to the foot, and continued successively upwards with the rest, making them cross each other at the anterior part of the leg.

On the sides were placed the bolsters which were doubled at the ancle to protect that part from the pressure it might otherwise sustain. The splints were then applied along the external surfaces of the bolsters, the edges of the junk-cloth having been previously folded round them, in order to render their pressure the more close and steady. Along the fore part of the leg was laid the largest of the bolsters, and the whole was then secured by the four pieces of tape tied on the external splint, with a degree of tightness sufficient to keep the fragments immoveable.

A compress wet with vegeto-mineral water covered the foot, and was secured by a roller, applied in such a manner, that its two ends, crossing on the back of the foot, were fastened laterally to the two splints.

The leg, being firmly fixed by this apparatus, and gently flexed by means of a pillow placed under it, was protected by hoops from the pressure of the bedcloaths. The fragments being now in complete apposition irritated the parts no longer, in consequence of which the pain ceased.

The patient being properly disposed in bed, remained tranquil and easy throughout the remainder of the day. Diluting drinks and light nourishment were prescribed.

Next day, no pain; patient composed; a slight swelling on the back of the foot; the apparatus wet anew with vegeto-mineral water. Fourth day, the bandages a little relaxed; the point of the foot turned somewhat outwards; a new application of the apparatus. Seventh day, bilious symptoms appear, loathing of food, nausea, and bitterness of the mouth. Eighth day, tongue furred, inclination to vomit; loss of appetite; a grain of tartar emetic given in solution; copious dejections; evidently better: next day, appetite returned, tongue clean. Tenth day, a third application of the apparatus, which had become too loose. Fifteenth day, fresh bilious symptoms; further evacuations; success the same. Twentieth day, consolidation evidently advancing; no deformity of the limb; fourth application of the apparatus. Thirty-second day, consolidation almost complete; the apparatus still kept on till the forty-second day, when the patient was discharged perfectly cured.

2. This case, which is in no respect different from those that most frequently occur in practice, presents us with a view of the mode of reduction, the means of retention, and the subsequent treatment, employed by Desault, in cases of the kind. The advantage of the bandage of strips, which allows the limb to be uncovered without being disturbed, is now generally acknowledged in fractures of the lower extremities. In the treatment of these, practitioners reject entirely, at present, the roller bandage, which was recommended by Petit, Heister, and all the authors who preceded them, and which, by producing a new displacement, at each time of reapplication, may entirely prevent the fragments from uniting. The bandage of Scultet, brought into use again by Desault, the form of which has been just described, is also preferable to the eighteen-tailed bandage, which some practitioners still employ.

3. The strips which compose the former bandage, being narrower than the tails of the latter, can be more neatly applied to the leg, as they more readily mould themselves to its inequalities; the compression made by them is, therefore, more exact, more uniform, and consequently less inconvenient. If one of the strips become soiled, it can be changed without deranging the bandage. (Respecting this point, see what was said on fractures of the thigh.) This bandage being less bulky than the eighteen-tailed one, is therefore less troublesome to the patient.

4. The broad and strong splints which form a part of this apparatus, have the following advantages over those previously used both by the ancients and the moderns; 1st, they come in contact with and bear on a larger extent of the surface of the limb; 2dly, they consequently maintain the fragments in apposition with greater firmness and effect; 3dly, they prevent the rotation of the foot outwards, an accident which very frequently occurs when the fracture is complete, that is, when both bones are broken; 4thly, they remain constantly in their place, without slipping either forward or backward, an inconvenience necessarily attendant on the other splints, which, from their roundish form, touch the limb in only one point or line.

5. To sustain the foot, Petit recommends a piece of a board to be applied immediately to its sole, and supported by two bits of tape fastened to the splints. This practice is adopted to some extent even at present: but a simple roller, applied in the manner already mentioned, is sufficient for the purpose; the tendency of the foot to turn outwards is never so strong as not to be effectually resisted by this expedient: besides, should the piece of board be placed ever so little too vertically, it retains the foot in a state of inconvenient and painful flexion.

6. The situation of the leg, gently flexed by means of a thick cushion or pillow placed between it and the mattress, is, in all respects to be preferred to the method of Pott, which is exclusively adopted by Bell. What, indeed, can be the object of this latter method? To relax, say they, the muscles, that tend to make the lower fragment overlap the upper one. But is it not evident, that most of these muscles, not being attached to the os femoris at all, cannot be influenced by this position? To obtain the relaxation of the posterior muscles, it is necessary to flex the foot; but, in such a case, the anterior muscles are necessarily in a state of tension: this completely counter-balances the relaxation of the others, and, therefore, there is nothing whatever gained. It is certainly much best to allow the leg to be in a state of moderate flexion, such as we assume when asleep, and which appears to be the most natural.

7. The apparatus just described, produces on the fragments a twofold action: 1st, by a kind of side walls formed by the splints, it prevents their displacement laterally, and from this circumstance alone, is fully sufficient for the retention of transverse fractures: 2dly, the pressure of the rollers, splints, and bolsters, if these be applied with sufficient tightness, prevents the lower fragment from mounting on the upper one, and thus preserves the natural length of the limb. Hence its advantages in oblique fractures; and, as the powers of displacement are weaker here than in the thigh, this apparatus, is in general, sufficient to counteract them.

8. It is true that cases do sometimes though rarely occur, where, in consequence, of being irritated by splinters, or the points of the fractured bone, or acted on by some other causes which make them contract, the muscles overcome the resistance of the apparatus, and make the fragments overlap. Under such circumstances, permanent extension affords here the same advantages as in fractures of the thigh.

9. Most authors, to obtain the desired end in such cases, recommend means calculated to act on the thigh. Thus, Manne proposes the use of his glaussocome. Desault, under such circumstances, effected his purpose by the apparatus described in the following case.

§ II.

10. CASE II. Pierre Bejol, aged thirty-seven, of a strong and vigorous constitution, fell, as he was carrying a heavy load, over a beam which lay in his way. His leg was fractured towards its lower part; he was lifted up and carried home, where a surgeon, by making unskilful efforts at reduction, gave him extreme pain.

A roller and a kind of round splint applied to each side of the limb, forming the whole of the apparatus, and not being sufficient to retain the fragments, soon allowed them to overlap each other nearly two inches. The pains continue; a considerable swelling appears around the fracture; the patient is greatly agitated; he is brought to the Hotel-Dieu, where, from the deformity of the limb, Desault was satisfied, at first sight, of the existence of a fracture; on a more attentive examination, it was discovered to be complete and very oblique.
