Posterior shoulder dislocation with a reverse Hill–Sachs lesion treated with frozen femoral head bone allograft combined with osteochondral autograft transfer

Management of a posterior shoulder dislocation with an associated reverse Hill–Sachs lesion is challenging, both diagnostically and therapeutically. Diagnosis is frequently delayed or missed, whereas the resulting humeral head defect is often larger and more difficult to salvage than in anterior shoulder dislocations. This report presents the case of a 29-year-old male with a recurrent posterior shoulder dislocation associated with a large reverse Hill–Sachs defect, treated with bone augmentation of the lesion with a combination of fresh femoral head allograft and a locally harvested humeral head autograft transfer, with a successful outcome.
