Evaluation of the accuracy and interobserver agreement of the reverse shoulder angle in the preoperative planning of reverse total shoulder arthroplasties
Our study demonstrated that the RSA angle can be reproducibly used to assess glenoid inclination on 2D CT images presenting high interobserver agreement. RSA differs significantly from the GGI, indicating that measuring glenoid inclination for reverse or anatomical arthroplasty requires distinct methodologies that account for the inherent differences in these angles.
