Osteoarticular allograft reconstruction for hill-sachs lesion in an adolescent.

چکیده
Glenoid and humeral head bone loss is the most common cause of failure after surgical shoulder instability stabilization. Large Hill-Sachs lesions involving >30% of the articular surface of the humeral head typically occur after neglected or locked shoulder dislocations. Such large lesions may require osteochondral allograft reconstruction or prosthetic replacement to regain shoulder stability and function.Previous reports of osteochondral allograft reconstruction have focused on adults. This article describes a case of a 16-year-old autistic boy who sustained an anterior dislocation of the right shoulder following a seizure episode. The dislocation was diagnosed 12 days later as a progressive deformity, and his parents noticed his inability to use his upper extremity. The patient had a large (30%) humeral head Hill-Sachs lesion and persistent anterior shoulder instability after initial closed reduction. He underwent an open osteochondral allograft reconstruction for the restoration of the humeral head articular surface. The sizing of the defect, matching harvest of the allograft, and perfect fit of the allograft to the defect are critical steps to ensure congruent restoration of the humeral head. The allograft was stabilized in the defect of the humeral head using cancellous screws placed from below the articular surface. Radiographs 20 months postoperatively showed complete incorporation of the osteochondral allograft. At 30 months postoperatively, his shoulder was stable and functional.

Osteoarticular allograft reconstruction of the distal radius after giant cell tumor resection
Abstract Background: Resection of the distal end of the radius is indicated in the treatment of locally aggressive primary benign and malignant bone tumors. The aim of this study was to evaluate the technique of osteoarticular allograft reconstruction of the distal radius after wide excision of a giant-cell tumor. Methods: We analyzed 15 patients retrospectively who had reconstruction of t...
