Abstract
We treated patients with severe slipped capital femoral epiphysisor SCFE with a posterior tilt angle or PTA of greater than or equal to 60 degrees with a Sugioka transtrochanteric rotational osteotomy. We report on the clinical and radiologic results of tis method.
The study was performed on 8 cases (including 9 hips) of slipped capital femoral epiphysis, for which transtrochanteric rotational osteotomy of femoral head (Sugioka method) was carried out in author’s department from 1987 to 1996. The age of onset ranged from 9 to 14 years old (average: 11.6 years). There were 4 boys (4 hips) and 4 girls (5 hips). The follow-up period ranged from 2 years to 10 years (average: 4.4 years). Three of the treated hips were classified as chronic and 6 as acute on chronic. Preoperative head-neck angle (HNA) was 64 – 83 degrees (average: 68 degrees). All patients were performed a transtrochanteric rotational osteotomy of the femoral head which is known as the Sugioka method. The rotational angle was from 70 degrees to 90 degrees. The presence of pain, postoperative range of motion, PTA on postoperative X-rays, avascular necrosis and osteoarthritic change were examined as part of the evaluation of the clinical results.
Necrosis of femoral head was found in one case, while no pain was noted in the other cases, and the range of motion was generally satisfactory. In the radiologic results, PTA was improved to 10 – 25 degrees (average: 18.5 degrees).
Necrosis of femoral head was observed in one hip, but the results were satisfactory in 7 cases (8 hips). These results suggest that this technique is useful for the treatment of severe cases of slipped capital femoral epiphysis
