The purpose of the present study is to report the mid-term results of modified Sugioka transtrochanteric valgus ostetomy (TVO) for the treatment of secondary osteoarthritis. The lateral displacement of the greater trochanter was simultaneously performed. Fourteen TVOs were performed in 14 patients with unilateral osteoarthritis of the hip from 1993. We assessed 8 hips in 8 patients in this study. The mean age of the patients at the time of surgery was 46.4 years (41 to 55 years). The average follow-up was 3.9 years (2.4-7.2years). The patients were evaluated for radiographic changes of the joint space, roof osteophyte, weight bearing surface of acetabulum, AHI, abductor lever arm, capital drop, bone cyst in the acetabulum or femoral head as well as clinical results using JOA score. The mean JOA score improved from 57.4 to 76.3. The widening of joint space, lengthening of weight bearing surface of acetabulum were seen in seven hips. The length of the abductor lever arm after surgery was not proportional to the JOA score at the latest follow-up. In one patient, total hip arthroplasty was required after 2.2 years. This procedure is considered useful for the treatment of osteoarthritis in dysplastic hips.
