[Unreduced congenital hip dislocation in adults]

Thirty-four cases of unreduced congenital dislocation of the hip were reviewed. The hips were completely dislocated and rode high with the femoral head supported by gluteal muscles, but not by a false acetabulum. The mean Harris hip score was 64 points. Twenty-four patients (80%) had mild or severe low backache, and this was associated with increased lumbar lordosis or functional scoliosis. Seven patients (20%) had valgus malalignment and dysfunction of the knee joint. In older patients over 50 years old, there were many significant problems in the hip, lumbar spine and knee.
