Mid-term results of the use of structural humeral head autograft to correct glenoid bone loss in reverse total shoulder arthroplasty

Abstract

Background: Native glenoid bone loss presents technical challenges in shoulder arthroplasty. The purpose of this study is to report the mid-term clinical and radiographic outcomes of patients treated with structural humeral head autograft reconstruction of glenoid bone loss in the setting of reverse total shoulder arthroplasty (rTSA). Methods: Retrospective review of 30 shoulders in 28 patients undergoing rTSA with a structural humeral head autograft to correct glenoid bone loss. Demographics, comorbidities, anatomic details, and patient-reported outcome measures were collected for analysis. Results: Range of motion and patient-reported outcome measures were all significantly improved postoperatively (P < .001). Bone grafts were found to incorporate into 100% of shoulders, with no protheses displaying signs of loosening or other structural concerns. No revision procedures were performed, and all patients were satisfied with their shoulder postoperatively. Two patients developed scapular notching on follow-up. Discussion: The use of a humeral head autograft to reconstruct glenoid bone loss in patients undergoing rTSA is a safe and effective procedure. It allows for a local graft source to be utilized thus avoiding potential comorbidity and complications associated with the use of alternative site autografts or allografts and has the advantage of nearly congruent fit within the defect.
