Reverse Shoulder Arthroplasty with a Glenoid-Sided Lateralized Prosthesis and Concomitant Latissimus Dorsi Transfer Is Associated with Early Proximal Humeral Osseous Erosion Without Superior Functional Outcomes.
BACKGROUND Reverse total shoulder arthroplasty (rTSA) using a lateralized implant design is commonly employed to address deficits in external rotation. In select cases, rTSA is combined with a concomitant latissimus dorsi tendon transfer (rTSA+LT) to augment external rotation. This study compared the clinical and radio...
