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.
