In reverse total shoulder arthroplasty (RTSA), a femoral head allograft can be used to address severe glenoid bone loss, which can be a significant issue and contribute to the failure of the prosthesis.

Specification Clinical Support

The study concluded that good outcomes were observed in patients who underwent primary Reverse Shoulder Arthroplasty (RSA) with bone graft augmentation. It suggests bone grafting can be effective even in highly challenging shoulder arthroplasty cases.
As the frequency of shoulder arthroplasty grows, so does the complexity of revision procedures, which often necessitate bone grafting to restore humeral length, ensure rotational stability, and address common glenoid bone loss. These revisions with bone grafting can notably improve patients' pain, motion, and function.
The study presents a novel technique to manage posterior shoulder instability caused by excessive retroversion of the glenoid using a femoral head allograft and instruments initially developed for high-tibial osteotomy. This osteotomy aims to prevent posterior displacement of the humeral head by increasing glenoid anteversion, thereby returning the glenoid to a more anatomical position to impede static posterior subluxation and potentially reduce the risk of glenohumeral osteoarthritis.
