6thly, Should the long compress prove insufficient to keep the foot extended, or should it, by becoming relaxed too soon, render frequent reapplications of the apparatus necessary, (circumstances which rarely happen when the bandage is well applied), a splint placed anteriorly, as was the case in Schneider’s apparatus (29), completely remedies the defect. 33. On comparing this apparatus with the indications formerly laid down, in the present disease (16), we find it evidently calculated to fulfil them with great exactness. 1st, The extension of the foot is permanently secured, both by the long compress, and by the splint when it is employed: 2dly, the same compress, aided by the bolster or pillow placed under the leg, maintains the flexion of the leg on the thigh: 3dly, The muscles are effectually compressed; their action is impeded in part by the compression of the circular bandage, which does not bear on the tendon, in consequence of the bolsters of lint placed on each side of it: these bolsters prevent the tendon both from moving laterally, and from being depressed: hence it follows, that the action of the circular bandage is precisely conformable to the principles already established (14 and 15); and that the whole of the apparatus, taken together, fulfils perfectly all the indications (16); this is an advantage not to be derived from any of the forms of apparatus used by preceding authors. 34. This apparatus is in no degree complex or troublesome. Simple and easy, it requires nothing for its construction but what the surgeon can easily obtain, and what he can even himself prepare. There exists a great analogy between it and the bandages which Desault used for the reunion of transverse wounds, and for fractures of the rotula and the olecranon. A truly great man does not estimate his merit, by the number of processes which he invents; he well knows that the perfection of art consists in producing numerous effects by few and simple means. 35. We will confirm, by two cases, the principles laid down in this memoir. One of these relates to a division of the tendon, connected with a wound, and was reported by Bezard; the other by Manouri, and relates to a simple rupture of the tendon. CASE I. J. B. Lavigne, aged thirty, as he was going down into a cellar without light, struck his leg against the edge of a sharp saw, which completely divided the tendo Achillis. The patient was immediately carried to the Hotel-Dieu. The wound of the integuments was transverse, two inches long, and had its edges but slightly separated from each other. The ends of the tendon, in contact during the extension of the foot, were separated two inches when it was flexed. The usual apparatus was applied (32), and the limb placed on a bolster, in a position favourable for the relaxation of the posterior muscles.
