Management of dislocation of the hip in Down syndrome.

Six patients with Down syndrome were treated for dislocation of the hip (10 hips). Follow-up averaged 49 months. Group I consisted of three patients (six hips) with dislocatable hips and normal acetabula treated with capsular plication and/or proximal femoral osteotomy. Group II consisted of three patients (four hips) with dislocatable hips and dysplastic and insufficient acetabula treated with capsular plication, Salter osteotomy, and proximal femoral osteotomy. Results were rated as satisfactory in four patients (seven hips) and unsatisfactory in two patients (three hips).

Cartilage necrosis due to pin penetration: experimental studies in rabbits.

An animal model was used to evaluate the role of pin penetration into the hip joint as the cause of chondrolysis. The gross and microscopic studies, as well as the biochemical studies, showed changes indicating cartilage destruction. These changes were more severe when the pins remained in the joint. Immunologic studies showed some type of immunological interaction. The immunologic response may be initiated by release of cartilage byproducts. The initial insult of the slip may cause release of cartilage byproducts from the exposed growth plate within the joint, and is compounded by penetration of the pin in the hip joint.

Osteocartilaginous lesion of the acetabulum resembling osteoid osteoma.

An unusual acetabular lesion radiographically resembling osteoid osteoma appeared in a 10-year-old girl recovering from trauma of the hip joint. Abnormal growth of cells of triradiate cartilage displaced by injury is a possibility that is supported by observations at open operation and biopsy.
