A Treatise on Fractures, Luxations, and Other Affections of the Bones

by P.-J. Desault

§ V.

LUXATION OF THE FOOT, COMPLICATED WITH AN ESCAPE OF THE ASTRAGULUS, THROUGH THE CAPSULE AND THE LACERATED INTEGUMENTS.

17. When, in a luxation of the foot, the integuments, capsule, and ligaments are so lacerated, as to suffer the astragulus to escape, it would oftentimes be imprudent to attempt its reduction, as was done in the preceding cases. The violence already done to the parts around the joint is excessive; but this would be increased by the extension, and other efforts necessary in reduction. Whatever care might be taken, it would be difficult to prevent a vast swelling, long continued pains, and perhaps even a caries of the bone exposed to the air, with all those sufferings and dangers, to which such an accident gives origin. In such a case all the bones of the foot have been known to become carious, a state of things, which calls for the ultimate resources of art, and draws after it a train of evils, which it is always of the utmost importance to prevent.

18. What means are then to be employed? Two expedients only remain. 1st, the amputation of the foot; 2dly, the extirpation of the astragulus. The first is a cruel resource, which should never be adopted but in the last extremity, because it deprives the patient of a portion of himself, necessary to the performance of his functions. But the measure is forbidden by a reason still more powerful. Amidst the general disorder of the system, the severe pains experienced by the patient, the convulsions, and the delirium which oftentimes exists, what ground has the surgeon to hope for success? Will not the operation add to the number of these alarming appearances? Will it not aggravate them? May it not render them fatal? Both reason and experience reply in the affirmative.

19. In such a case, then, the extirpation of the astragulus is the expedient to be preferred. What, indeed, are its inconveniences? 1st, An inevitable anchylosis of the foot and leg: 2dly, a shortening of the affected limb. But a leg even in this state, is still better than a wooden leg, which is the necessary consequence of amputation: besides, a leg of the former description occasions no great inconvenience in either walking or standing, whereas one of the latter, produces extreme lameness: in the first case, a heel on the affected side somewhat higher than that on the other, is an easy method of removing the deformity. What, then, are such trifling disadvantages, when compared with the evils which they ward off? The extirpation of the astragulus is accompanied with but little pain. The want of this intermediate body between the leg and the foot, by producing a relaxation of the surrounding soft parts, prevents pain and swelling in such cases: should abscesses supervene, they will not, if properly treated, greatly retard the cure. In a word, experience coincides with this doctrine. Desault has seen it twice verified in the practice of other surgeons, and three times in his own. I have known of but one case of the kind, in which the termination was fatal, and there, a malignant fever, induced by the contaminated air of the hospital, certainly contributed to the death of the patient, which did not occur till two months after the reduction.

Case VI. Desault usually gave in his lectures, the history of a case where the success of this practice was remarkable. A man was brought to the Hotel-Dieu, with a luxation of the foot, complicated with a fracture of the lower part of the leg, and a laceration of the ligaments and capsule, through which the astragulus had escaped by a luxation forward and upward, so as to have half of its anterior surface exposed. The extent of the injury seemed to call for amputation. But the youth, the vigour, and sound constitution of the patient, gave ground to hope that a process less desperate might succeed. The astragulus, already separated anteriorly, was extracted by dividing the attachments which held it to the os calcis, and the bones of the leg: the reduction was then effected without difficulty. The parts being replaced more readily in consequence of the removal of this bone, were retained so by means of a bandage similar to that for fractures of the leg, but modified so as to suit the particular case. The patient lost blood once or twice: the apparatus was kept constantly wet; a very strict regimen was prescribed for some days; but few troublesome symptoms occurred; a slight swelling took place, but was soon removed; a favourable suppuration came on; the dressing was renewed twice a day; some splinters escaped occasionally; several abscesses formed successively were opened, and healed up again: the wounds themselves closed, and the patient finally recovered, with an anchylosis, indeed, between the foot and leg, and a limb a little shorter than natural, but which still served the purposes of walking and standing.

20. To this example, I might add those of other patients treated at the Hotel-Dieu, in the same manner and with equal success. But what purpose would such an accumulation of facts answer? It would only fatigue the reader without adding to his conviction.

21. If the injury accompanying the luxation be so extensive, as to destroy the principal blood-vessels, and leave no hope of saving the limb, amputation becomes then the only resource, and the case assumes a resemblance to those where the limbs are shattered by cannon balls: the success then depends very much on the strength or weakness of the patient.

Case VII. A man fell from a carriage: his foot becoming entangled between the spokes of the wheel, was almost separated from the leg. It adhered only by a small portion of skin behind, and by the tendons of the muscles which run to the toes both above and below.
