5-Minute Summary: Radiographic Measurements in Reverse Total Shoulder Arthroplasty: Accuracy of Preoperative Planning

The use of preoperative three-dimensional (3D) planning software has increased when preparing for reverse total shoulder arthroplasty (RSA). Malpositioning of the glenoid baseplate and, subsequently, the glenosphere has been linked to poor patient outcomes and increased rates of revisions. The purpose of this study was to evaluate the accuracy of the radiographic measurements, version, inclination, and RSA angle, in preoperative imaging, the preoperative plan, and postoperative imaging.
