Prediction of Impingement-Free Range of Motion Prior to Reverse Shoulder Arthroplasty

Preoperative planning for reverse shoulder arthroplasty (RSA) using 3D automated software has been increased in practice in the past few years. It has been used to improve accuracy on implant placement, size and selection, especially in the glenoid side. New additions have been added however, to look at prediction of range of motion (ROM). Therefore, the purpose of this study was to assess the accuracy of predicting impingement-free range of motion (ROM) of a 3D preoperative planning software.
