BACKGROUND: Revision of a shoulder arthroplasty to a reverse shoulder arthroplasty in the presence of glenoid bone loss is especially challenging. The purpose of the present study was to determine the complications and results of glenoid bone-grafting in revision to a reverse shoulder arthroplasty.
METHODS: Between 2005 and 2010, 143 consecutive reverse shoulder arthroplasties performed as revision procedures were performed at our institution. Glenoid bone-grafting was performed in forty-one shoulders (29%), with 98% (forty) that had follow-up of more than two years (mean, 3.1 years). The 102 patients who did not undergo grafting served as a control group.
RESULTS: Seven patients (18%) required another revision surgery because of glenoid loosening (four patients), instability (two patients), or infection (one patient).
