Functional improvements in active elevation, external rotation, and internal rotation after reverse total shoulder arthroplasty with isolated latissimus dorsi transfer: surgical technique and midterm follow-up

摘要

Hypothesis: This study investigated the hypothesis that reverse total shoulder arthroplasty (RSA) in combination with an isolated latissimus dorsi tendon (LDT) transfer in patients with pseudoparalysis of abduction and external rotation (combined loss of active elevation and external rotation [CLEER] syndrome) would demonstrate improved postoperative functional results.
