Abstract

Scapular stress fracture (SSF) after reverse total shoulder arthroplasty is a unique and common complication that may have negative impact for long-term outcomes. Scapular stress reaction (SSR), characterized by pain and tenderness without radiographic evidence of fracture, can be precursor of SSF. We believe that early detection using SPECT/CT with proper management for SSRs including acromion, scapular spine, and coracoid process is crucial for better prognosis without additional complications by preventing SSFs. Therefore, we present 3 typical cases with SSR following reverse total shoulder arthroplasty with the findings of SPECT/CT.
