The Influence of Reverse Arthroplasty Humeral Component Design Features on Scapular Spine Strain

Reverse shoulder arthroplasty (RSA) humeral implant parameters have been previously studied with respect to range-of-motion, deltoid function, and stability. However, limited literature exists on the influence of humeral design features on scapular spine strain. The purpose of this cadaveric biomechanical simulator study was to evaluate the role of humeral component lateralization and neck-shaft angle (NSA) on scapular spine strain.
