Congenital dislocation of the hip.
From January 1970 to December 1976, seventeen patients with twenty-two congenital hip dislocations were treated by open reduction through a medial approach. The average follow-up was 42.2 months. The patients were evaluated for acetabular development, aseptic necrosis, and intraoperative findings. The incidence of aseptic necrosis was 10 per cent. The acetabular index improved rapidly during the first year after reduction. After the first year the rate of development was decreased, but the acetabular index continued to improve throughout the period of study. The medial approach provides a safe, effective way to reduce a dislocated hip in infancy. This procedure is advocated when closed reduction cannot be obtained by gentle manipulation or maintained by positioning once reduction is done.
