    摘要： A method for restoration of stability and painfree rotation of the distal radio-ulna joint is based on raising the capsulo-retinacular flap by dissection off the dorsal part of the triangular fibro-cartilage complex distally and off the neck of the ulna proximally. After resection of the ulna head and reaming the distal end of the ulna to an appropriate depth and inserting the prosthesis into a suitable position the dorsal aspect of the triangular fibro-cartilage complex is reattached to the underside of the flap. Finally, the flap is reattached to the sigmoid notch of the radius and the wound is closed. By this way, painfree forearm rotation is restored and at the same time any length discrepancy is corrected.

    摘要翻译： 用于恢复远端放射性尺骨关节的稳定性和无疼痛旋转的方法是基于通过从近端的三角形纤维 - 软骨复合体的背部和远端的尺骨的颈部解剖来提高囊 - 视网膜瓣。 在切除尺骨头后，将尺骨的远端延伸到适当的深度并将假体插入合适的位置，将三角形纤维软骨复合体的背侧重新连接到瓣的下侧。 最后，将瓣片重新连接到半径的乙状切口，伤口闭合。 通过这种方式，恢复无痛的前臂旋转，同时校正任何长度差异。

    摘要： A lunate implant includes a one-piece, at least semi-rigid body defining a triquetrum face, a scaphoid face, a cupped, concave, distal surface adapted to articulate with the capitate bone, a proximal surface, a plamar surface and a dorsal surface. A pair of spaced, generally parallel suture passages extend between and open through the triquetrum and scaphoid faces. A pair of sutures are stitched to ligaments of the wrist. The ends of the sutures are passed through the suture passages so that one of the sutures has ends extending away from the triquetrum face and the other suture has ends extending away from the scaphoid face. The ends are grasped and the lunate implant is pulled down into the desired position in the distal carpal row of the wrist. The sutures are tied adjacent the implant to stabilize and position the implant.

    摘要： A flexible implant for replacement of the lunate bone of the wrist includes a one-piece body of resilient material defining a planar triquetrum face having a general U-shape in plan and further including a stabilizing stem extending outwardly from and perpendicular to the planar triquetrum face and a planar scaphoid face having a generally U-shape in plan extending at an angle with respect to the triquetrum face. The body further includes a cupped, concave, smooth distal surface adapted to articulate with the head of the capitate bone. The body defines a proximal surface having a smooth convex shape and extending between the proximal edges of the triquetrum and scaphoid faces. Generally planar palmar and dorsal surfaces extend between the dorsal lateral edges and the palmar lateral edges of the triquetrum and scaphoid faces.

    摘要： Wrist joint prosthesis. As a replacement for the joint in a human wrist, there is provided a prosthesis permitting both vertical motion, sidewise motion and rotary motion but preventing twisting motion around an axis projecting from and parallel with the lower forearm. For this purpose, there is provided a metal socket fitted with a prong receivable into a bone of the forearm. A plastic cup made of material self-lubricating with respect to such metal socket is fitted within said socket, snappable thereinto to resist but not prevent withdrawal therefrom and having a rectangular projection-and-slot relationship with said metal socket to permit relative motion with respect thereto in only a single plane. A metal ball is receivable into the recess of said plastic cup, snappable therewith to resist but not prevent withdrawal therefrom and has a rectangular projection-and-slot relationship with the inside of said plastic cup to permit relative movement with respect thereto in only a single plane, said plane being substantially perpendicular to said first-named plane. Suitable projections are provided on said ball for reception into the bones of selected fingers, normally the index and middle finger. Placement of said prosthesis in one position or a mirror image thereof will render said prosthesis without other change adaptable for use with one hand or the other hand as desired.

    摘要： A prosthesis for the trapezium of the thumb carpometacarpal joint comprising an integral elastomeric member configured to include a generally cylindrical portion, having extending from one end thereof an elongated, longitudinally extending tapered portion adapted to be embedded into a reamed out-channel in the thumb metacarpal bone, while the opposite end of said cylindrical portion is slightly concave to conform to the navicular bone, and wherein said cylindrical portion includes a transverse aperture. In the subject method following the step of implanting the tapered projection of the subject prosthesis in the thumb metacarpal bone, the axis of the aperture is aligned perpendicular to the plane of the thumb, and a segment of the flexor carpi radialis tendon is then passed over the cylindrical portion of said prosthesis and down through the aperture, and then fixed to the main portion of said tendon, thereby forming a reinforced structure to inhibit dislocation of the prosthesis.
