Use of locking humeral stems in reverse total shoulder arthroplasty for complex proximal humerus fractures: a scoping review.

ABSTRACT: The use of locked humeral stems in reverse total shoulder arthroplasty (rTSA) has emerged as an alternative fixation strategy for treating complex proximal humerus fractures (PHFs). This scoping review synthesizes the available literature evaluating clinical outcomes, radiographic findings, and complications associated with interlocking humeral stems in rTSA for PHFs. Nine studies, encompassing 434 patients, were identified, of whom 308 underwent rTSA with a locking humeral stem. The mean patient age was 75.7 ± 5.1 years, with a mean follow-up of 20.0 ± 8.9 months, and at least 54% of patients were female. Postoperative functional outcomes demonstrated a mean forward flexion of 120° ± 13.2°, abduction of 101° ± 2.3°, external rotation of 29.3° ± 8.9°, and internal rotation to the lumbar sp
