Reverse shoulder arthroplasty with bone defect

Reverse total shoulder arthroplasty (RSA) has proven to be an effective treatment regimen for patients dealing with rotator cuff tear arthropathy. In recent times, its scope has broadened to encompass cases of osteoarthritis (OA) featuring posterior subluxation, a biconcave glenoid, or other advanced symmetrical glenoid wear patterns, as well as instances such as tumor resection, post-infectious complications, and chronic dislocations.
Nevertheless, there are lingering concerns about the long-term outcomes of RSA, particularly the potential for implant loosening, especially when glenoid bone defects are present. It's worth noting that glenoid bone deficiency is a prevalent issue among RSA recipients. The primary methods employed to address this bone deficiency in RSA include bone grafting and eccentric reaming. However, these techniques have yielded mixed results over the long haul, with worries revolving around implant stability, medialization of the joint line, and the possibility of bone graft resorption.
