Abstract:
Disclosed herein is a minimally invasive ball joint implant and prosthesis for the treatment of arthritis, trauma, and other medical conditions leading to joint destruction and pain, as well as methods of use. In various cases, the prosthesis does not require reaming into the intramedullary canal and does not require diaphyseal fit for any bones associated with the joint, thereby resulting in more rapid and complete recovery. In various cases, the prosthesis incorporates an anchoring stem specifically designed to be impacted into the bone and to facilitate bony ingrowth after implantation, thereby strengthening the implanted prosthesis and preventing rotation thereof.
