Effect of combined version on impingement-free rotational range-of-motion in three different implant types in reverse shoulder arthroplasty
This study demonstrates that total impingement-free ROM in rTSA decreases with combined component version greater than 30° of retroversion. The study also demonstrates increased total ROM with implant designs that create a more lateralized center of rotation (MG-LH, LG-MH). Impingement location changes with implant design, with less scapular neck impingement found with the LG-MH design. The study is limited by not being able to account for scapulothoracic motion or soft tissue considerations.
