IMPLANTABLE PROSTHESES

摘要

Prosthesis, tools and surgical methods treat joint instability by avoiding loosening over time. A shoulder prosthesis includes a humeral member with a humeral joint surface and a humeral fixation member and a glenoid member comprising a glenoid body with a glenoid joint surface, and a glenoid fixation member attaching the glenoid body to a scapula. The glenoid fixation member may be attached orthogonally to the scapula. A dampener may be included to absorb loads that may loosen one or more components of the prosthesis.
