Apparatus for locating an elbow prothesis.

摘要

An elbow prosthesis (41, 60, 82) and a jig (1) for ensuring accurate placement of same is described. The jig (1) is accurately located around the patient's elbow and using a first selected tool holder the humerus is prepared with a convex end from the medial side. Without moving the jig (1), a complementary concave end is prepared in the ulna using a second selected tool holder. The radius is prepared, from the lateral side of the elbow, with a straight cut. The humeral portion (41) of the prosthesis is slid into place over the convex end of the prepared bone, the ulna portion (60) of the prosthesis is secured by pinning to the concave end of the prepared bone and the radial portion (82) of the prosthesis is secured to the straight end of the radius by pinning thereto and the thickness thereof is adjusted to provide proper articulation clearance with the humeral portion (41).
