Mechanism | Reported technique | Osteo-chondral allograft |
---|---|---|
Restoration of humeral head sphericity and smooth articular arc | + | + |
Concurrent posterior capsulorrhaphy | ± | ± |
Conversion of intra-articular residual reverse Hill-Sachs defect into an extra-articular one by lesser tuberosity (± SSC) trans-fixation into the defect | Might be needed following fibular grafting according to intra-operative assessment of geometry and engagement of the residual defect | Not needed as it fully reconstructs the defect |
