Acute dislocation of the patella with osteochondral fracture: a review of eighteen cases.

Eighteen patients with acute dislocation of the patella had associated osteochondral fractures. This fracture complicates approximately 5% of all acute dislocations of the patella occurring in children. Three types of fracture patterns were noted. All patients who were treated by immediate arthrotomy and excision or replacement of the osteochondral fragment and repair of the acute dislocation of the patella made an uneventful recovery with no recurrence of the dislocation. In those patients in whom the osteochondral fragment was removed but with no repair the dislocation recurred.

Immunology of cartilage in septic arthritis.

Septic arthritis in one knee joint was produced in 18 rabbits, the contralateral knee being left intact. Sections stained with fluorescein conjugated anti-IgG and with fluorescein conjugated anti-IgM showed layers of immunoglobulins on the articular cartilage in 16 out of 17 injected joints, and 10 out of 17 supposedly "normal" knee joints. Concurrent tests for circulating anti-staphylococcal alpha-lysin gave negative results. Cultures of synovial fluids were negative. These observations suggest that articular cartilage may act as an auto-antigen; immunological mechanisms involved may be due to the combined activity of both cell-bound and humoral antibodies. There are 2 components to a septic arthritis, the primary being a bacterial and the secondary immunologic in nature.

Butler arthroplasty for correction of the adducted fifth toe: a retrospective study of 36 operations between 1968 and 1982.

This is a retrospective study of 30 children and adolescents who have undergone Butler arthroplasty for correction of an overriding fifth toe. Bilateral operations were performed on six patients, giving a total of 36 operations. Good to excellent results were obtained in 34 of the 36 operations. With attention to detail, this is a simple and safe operation. Full correction is obtainable without postoperative splintage or cast immobilization. This study represents the only reported experience in North America of this little-known procedure.

Spine deformity in familial dysautonomia (Riley-Day syndrome).

Familial dysautonomia spanning a 30-year period reviewed retrospectively. The 16 patients identified included nine with spine deformities. Serious general medical problems were common. Spine deformities included kyphosis, scoliosis, or a combination of both. Brace treatment was attempted and was unsuccessful in three patients. Seven underwent surgical stabilization. Although all seven patients tolerated the surgical procedures, at least one postoperative complication was noted in each case. Follow-up ranged from 1 1/2 to 16 1/2 years. We recommend close observation of the deformities, early stabilization when disorders are progressive, and a high level of awareness of potential complications.
