Managing Severe Glenoid Defects during Revision Surgeries Following Reverse Shoulder Arthroplasty Using Femoral Head Allograft: A Technical Note with Preliminary Findings

This report details our experience and technique for addressing massive uncontained defects of the glenoid during revision in reverse total shoulder arthroplasty. The glenoid reconstruction was performed in a two-stage approach, with the initial stage involving the removal of all implants and the grafting of allogenic femoral head bone into the glenoid defect. Following confirmation of bone block consolidation on a CT-scan, the second stage entailed the implantation of the glenoid base over the bony block. Our results show no cases of loosening, implant failures.
