Intermedullary rod apparatus for repairing proximal humerus fractures

A bone stabilizing apparatus includes a stem member and an extension member, 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. The extension member (2) has radially directed threade...

More Information
Summary:A bone stabilizing apparatus includes a stem member and an extension member, 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. The extension member (2) has radially directed threaded holes either pre-formed or created after the bone stabilizing apparatus is installed into the humerus. The threaded holes (20) allow fixation of stabilizing screws (22) with suture posts (28), 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 can be attached to the extension member. In a preferred embodiment a guide structure directs the drill and stabilizing screws radially through the central axis of the extension member.
