What is the best glenoid configuration in onlay reverse shoulder arthroplasty?

摘要

Purpose The purpose of this study was to analyze the effect of different glenoid configurations on ann position and range of motion (ROM) following reverse shoulder arthroplasty (RSA). The hypothesis was that different glenoid configurations would lead to changes in humeral offset, acromio-humeral distance (AHD), ROM, and rotator cuff muscle length.
