Anterior glenoid bone loss is present in nearly all cases of recurrent anterior glenohumeral instability. Treating glenoid bone loss in the setting of recurrent instability is challenging, and often, soft tissue stabilization procedures in isolation are inadequate. The nonanatomic, incongruous joint resulting from most bony augmentation procedures has motivated investigators to find an alternat...

Purpose. The purpose of this study was to compare the oncologic, reconstructive and functional outcomes of patients who underwent osteoarticular allograft reconstruction with those who underwent arthrodesis for a primary malignant bone tumour of the proximal humerus.Patients. Eleven patients were treated with osteoarticular allograft reconstruction of the proximal humerus. Five of these reconst...

BACKGROUND Because of concerns about infections with the use of fresh osteoarticular allografts, osteoarticular allografts are currently stored hypothermically for a minimum of fourteen days to allow for serologic and microbiologic testing prior to implantation. Refrigerated osteoarticular allograft transplants are often used to treat symptomatic chondral and osteochondral defects in young, act...

Fractures and nonunions are the main complications associated with bone allografts. Although the osteogenic role of recombinant human bone morphogenetic proteins (rhBMPs) has been demonstrated in experimental models and human tibial nonunions, the results are unknown for allograft nonunions. In this study, the efficacy of rhBMPs was evaluated in nonunions of femoral allografts. The results of s...

The outcome of tibial allograft reconstruction after resection of a tumour is inconsistent and has a high rate of failure. There are few reports on the use of tibial allografts in children with open growth plates. We performed 21 allograft reconstructions (16 osteoarticular, five intercalary) in 19 consecutive patients between seven and 17 years of age. Two had Ewing's sarcoma, one an adamantin...

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 ...

Osteochondral defects of the femoral head are exceedingly rare, with limited treatment options. Restoration procedures for similar defects involving the knee and ankle have been well described. In this report, we present a young patient who had a symptomatic osteochondral defect of the femoral head develop secondary to trauma and underwent subsequent treatment using a fresh-stored osteochondral...
