Problems solved by technology

[0012] However, the use of such known modular implants still requires the use of reamers, reamers, and other bone tissue removal instruments to create a bone cavity extending from the resection down into the medullary canal
Therefore, joint replacement and hemiarthroplasty remain highly invasive procedures which can lead to recovery complications such as longer healing process, further damage to the patient, disease, pain and arthritis

Abstract

Disclosed herein is a minimally invasive ball joint implant and prosthesis 10 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 10 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 10 incorporates an anchoring stem 38 specifically designed to be impacted into the bone and to facilitate bony ingrowth after implantation, thereby strengthening the implanted prosthesis 10 and preventing rotation thereof.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 61 / 340,085, filed March 11, 2010. The entire disclosure of this application is incorporated herein by reference. technical field [0003] The present disclosure relates to full or partial joint prostheses and methods, all of which are capable of reproducing with good accuracy the characteristics of a natural joint. Background technique [0004] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0005] Joint replacement and hemiarthroplasty are common treatments used to reconstruct shoulder and hip injuries. Currently, as many as 23,000 Americans undergo shoulder replacements and approximately 120,000 Americans undergo hip replacements each year. These procedures are performed to treat conditions such as osteoarthritis, rheumatoid arthritis, traumatic arthritis,...
