title: Use of allograft for large Hill-Sachs lesion associated with anterior glenohumeral dislocation. A case report.
abstract: Though Hill-Sachs lesion is a common injury associated with anterior glenohumeral dislocation, there have been only few articles describing specific treatments for the humeral head defects. This paper described the case of an alternative treatment for large defect of the posterior-superior aspect of the humeral head using allograft. The patient was a 69-year-old male and the diagnosis was a chronic anterior dislocation of the right glenohumeral joint with a large impaction fracture of the posterior-superior aspect of the humeral head. The size of this defect was 4 cm by 2.5 cm in diameter with a 2 cm depth. To reduce the impaction fracture of the humeral head, a preserved frozen allograft of the femoral head was selected and configured to fit the defect. The graft was then impacted firmly down into the defect, and appeared to offer excellent stability even without adjuvant internal fixation. Two years after surgery, the patient was doing quite well with no complaints. Radiographs showed humeral head with incorporation of the graft and no evidence of collapse.
