Abstract
1. A small personal consecutive series of children with congenital dislocation or subluxation of the hip who came for treatment at the age of over three years has been reviewed. The children have been kept under review up to the age of ten years or more.
2. A number of late results are illustrated. They lead to the conclusion that open operation is indicated in all these cases and that acetabuloplasty will effectively provide stability in most, particularly when combined with osteotomy of the femur with adduction angulation and lateral rotation.
3. It is still too early to assess the value of pelvic osteotomy of the Salter (1961) or Chiari (1955) type.
4. Capsular arthroplasty appears from Trevor's (1960) considerable experience to have a valuable place in patients over six years old.
