Combined intertrochanteric valgus and rotational acetabular osteotomy.
Results are reported for combined intertrochanteric valgus and rotational acetabular osteotomies in 18 dysplastic hips (17 patients), involving two types of femoral head and neck deformities, after an average followup of 13 years (range, 8.9-22.6 years). The mean age of the patients at the time of surgery was 25 years (range, 11-36 years). Pain was the indication for surgery in all patients. The preoperative deformities were classified into two groups. Hips in Group I had an angular head and a normal or valgus neck. Hips in Group II had an ovoid head, a short neck in varus angulation, and relative overgrowth of the greater trochanter. There were seven hips (seven patients) in Group I, and 11 hips (10 patients) in Group II. The sum of the most recent pain score and gait score of Merle d'Aubigné (a full score of 12 points) was 11 to 12 points for seven of 11 hips of Group II, and 11 to 12 points for only one of the seven hips of Group I. For patients with hip pain in Group II, this operation fairly consistently relieves pain for at least an average of 13 years, but whether the rate of development of osteoarthrosis is retarded is not known.
