Abstract

An orthopedic medical device assembly that includes a first bearing for attachment to an implant and a second bearing for attachment to an implant, such as a glenosphere.

Description

BACKGROUND OF THE DISCLOSURE[0001]The exemplary embodiments of the subject disclosure relate generally to a reverse shoulder arthroplasty (RSA) system.[0002]RSA restores a fulcrum on the glenoid so that the deltoid can then rotate the arm upward. This is accomplished by taking an unconstrained joint (i.e., a large ball on a small socket) and converting it to a constrained joint (i.e., introducing a large socket to replace the ball and a small ball to replace the socket). This constraining of the joint is a reason why RSA outcomes are predictably good, as the constrained implant does all the work and does not rely on soft tissue to achieve stability and function. These advantages have allowed RSA surgeries to gain prominence, now being used for more indications to treat a wider domain of subjects.[0003]Nevertheless, RSA still has room for improvement. One drawback with RSA is the appearance of the shoulder after the surgery, i.e., the dropped shoulder deformity. This is particularly ...
