INTERMEDULLARY ROD APPARATUS AND METHODS OF REPAIRING PROXIMAL HUMERUS FRACTURES

摘要

A bone stabilizing apparatus includes a stem member (1) and an extension member (2), the stem member (1) having a distal end (6) for insertion within the intramedullary canal of a human humerus, and the proximal end (8) connected to the extension member (2). The extension member (2) has radially directed threaded holes (20) either preformed or created after the bone stabilizing apparatus is installed into the humerus. The threaded holes (20) allow fixation of stabilizing screws (22, 24) with suture posts, or a washer structure (26) to grip the surface of the bone and/or surrounding ligaments or muscle. A prosthetic or the natural humeral head (66, 112) can be attached to the extension member. In a preferred embodiment, a guide structure (46) directs the drill and stabilizing screws radially through the central axis of the extension member (2).
