The purpose of this investigation was to verify a long-standing clinical observation that patients with fracture of the proximal end of the femur have less evidence of osteoarthritic changes in their hip joints than would have been expected in patients of similar age groups. The radiographs of 342 patients with fractures and those of 157 controls were(More)
We determined the acetabular angles, center-edge angles, comprehensive quotients, and Shenton's lines from sequential roentgenograms of thirty-seven children with congenitally dislocated hips treated by closed non-manipulative reduction in early infancy. The values were compared with those obtained from roentgenograms of 164 normal children who ranged in(More)
The effect of overuse and overuse combined with axial peak overloading on the knee joints of living rabbits has been investigated. A specially constructed apparatus was used for this purpose. Physical and biochemical changes are reported and include: 1. Early and progressive damage to the articular cartilage surface shown by the scanning electron(More)
In 2 children with cysts in the upper end of the femur, there were 3 complications: coxa vara, avascular necrosis and osteochondritis dissecans. Coxa vara occurred in both cases and was due in 1 case to pathological fracture, and in the other case to growth disturbance. Avascular necrosis of the femoral head, a hitherto unreported complication of bone cyst(More)
