  Twenty patients intervened with combined osteotomy. There were nineteen males and one female with a mean age of 7.7 years. The average follow-up was 49 months. Nine had a Catterall III and eleven had a Catterall IV. According to Herring classification, fourteen patients were Herring B and six were Herring C. In accordance with the Ratliff classification, the postoperative clinical results: fifteen good, three fair and two poor.
