The Validity of Radiographic Measurements Compared to 3D-surface Model-Based Measurements in Shoulders with Reverse Total Shoulder Arthroplasty.

Background: Postoperative assessment following reverse total shoulder arthroplasty (rTSA) typically involves plain radiographs to evaluate implant positioning parameters, such as humeral distalization and lateralization along with medialization and distalization of the center of rotation (COR). However, the precision of these radiographic measurements remains unclear. This study aimed to validate the accuracy of radiographic two-dimensional (2D) measurements compared to three-dimensional (3D) surface model-based measurements derived from CT data for evaluating postoperative parameters in rTSA.
