Functional internal rotation after shoulder arthroplasty: a comparison of anatomic and reverse shoulder arthroplasty

摘要

Background: Recovery of functional internal rotation after primary shoulder arthroplasty is essential to perform many important activities of daily living. Functional internal rotation is typically reported as it relates to clinical examination findings of motion (posterior reach) and lift-off or belly-press tests. A more detailed evaluation of functional recovery of internal rotation after primary anatomic total shoulder arthroplasty (TSA) and reverse shoulder arthroplasty (RSA) is needed.
