Total hip replacement in congenital dislocation and dysplasia of the hip.

The results of thirty-one total hip replacements in twenty-four patients with either severe congenital dysplasia or dislocation, after an average follow-up of four years, were excellent in eleven, good in sixteen, fair in one, and poor in one. The operative technique included superolateral bone grafts to increase the acetabular coverage in six hips. Twenty-seven hips required smaller and straighter femoral components than normal. The incidence of major complications was 19 per cent.
