Presentation description

Reverse total shoulder arthroplasty (rTSA) replaces the humeral ball with a cup and the glenoid socket with a hemisphere in patients who experience degenerative changes, acute injuries, and shoulder instability. The aim of this study was to model patient specific shoulder anatomy and compare muscle moment arms between healthy controls and post-operative rTSA patients. Changes in the post-operative muscle moment arms may be useful in quantifying post-operative functional advantages or limitations
