Abstract
We made comparative examinations on cases of preosteoarthritis treated by rotational acetabular osteotomy to study the relationship between clinical and radiographic evaluations. Many conventional radiographic evaluations have been made chiefly from the frontal plane only. We tried using a modified inlet view to ascertain more accurately the acetabular coverage.
The results were that no direct correlation was observed between pain, gait and mobility, and the angles of CE and AC. With respect to the degree of pain, whether the limbus has been damaged (as determined by arthrographic study) is important as an indicator in the osteoar-thritis of relatively young patients in the second and early third decades. The inlet view was found to be useful for evaluating the preoperative and postoperative acetabular coverage.
