Comparative StudyPlate fixation of ununited humeral shaft fractures: effect of type of bone graft on healing.
Delayed union or nonunion of a fracture of the humerus is an infrequent but debilitating complication. Open reduction and internal fixation combined with autologous bone-grafting can result in reliable healing of the fracture; however, there is morbidity associated with the bone-graft donor site. This study was designed to evaluate healing of ununited fractures of the humeral shaft treated by one surgeon at one institution with a strict and consistent surgical protocol but with the use of two different types of bone graft: autologous iliac crest bone graft and demineralized bone matrix. ⋯ Therapeutic Level III.

The number of total shoulder arthroplasties has increased exponentially over the last ten years, creating a more prominent role for revision shoulder arthroplasty in the future. The main reasons for failure of shoulder arthroplasty can be classified as soft-tissue deficiencies, osseous deficiencies, component wear, or infection. We hypothesized that, despite appropriate surgical techniques, the outcome of revision total shoulder replacement can be predicted on the basis of the indication for the revision procedure. ⋯ Prognostic Level II.

Oncologic and functional outcome following sacrectomy for sacral chordoma.
Sacral chordoma is a rare, low to intermediate-grade tumor that poses substantial challenges in terms of timely diagnosis and adequate treatment. Few studies have examined the oncologic and functional outcomes of patients treated for sacral chordoma. ⋯ Therapeutic Level IV.

Comparative StudyLateral acetabular growth stimulation following a labral support procedure in Legg-Calve-Perthes disease.
The main goal of containment treatment in cases of Legg-Calvé-Perthes disease is to prevent hip deformity, which leads to arthritis in adulthood. Recently, the shelf arthroplasty (the labral support procedure) has been proposed as a method of containment. The purpose of the present study was to evaluate growth stimulation of the acetabulum in patients with unilateral Legg-Calvé-Perthes disease by measuring acetabular depth and height following treatment with the labral support procedure. Uninvolved, contralateral hips and hips that were treated with proximal femoral varus osteotomy were used to compare growth. ⋯ Therapeutic Level III.
