Abstract
In Japan there are many cases of secondary osteoarthritis of the hip caused by LCC or dysplasia of acetabular roof.
We discussed the principle of the treatment for the adolescent or young adult patients with dysplastic painful hips. Up to this time the operation such as varus osteotomy of the femur, shelf operation or Chiari's pelvic osteotomy have been performed for them.
From the standpoint of anatomical and functional treatment, we prefer “rotational acetabular osteotomy” among these various procedures.
It seems to be the best treatment for teen-agers or young adults, in which the femoral head is able to be placed more centrally and covered fully by the rotated acetabulum. A typical case was presented here.
