OBJECTIVE: To make a clinical and radiographic evaluation of intertrochanteric triplane osteotomy in the treatment of patients with chronic slipped capital femoral epiphysis. METHOD: 25 hips of 23 patients with chronic slipped capital femoral epiphysis (EEPF) submitted to intertrochanteric triplane osteotomy from 1987 to 2003 were evaluated retrospectively. Sixteen of the patients were male, and seven, female, with a mean age of 14 years and one month, who had a mean clinical and radiological follow-up of nine years and three months. Surgery was performed in patients with moderate or severe slip according to the Sothwick scale (mean of 57°). RESULTS: The Southwick clinical and radiological classification was used to evaluate the results and results were 84% of excellent and good according to the clinical criteria of pain and function, and 72% of excellent and good results according to the radiological criteria, with a final evaluation of 76% of excellent and good results. Out of the four bad results achieved, two presented chondrolysis, and two developed joint degeneration. No case of avascular necrosis was seen. CONCLUSION: Intertrochanteric triplane osteotomy is a good treatment option for the cases of EEPF with a slip greater than 30°, yielding good and excellent clinical and radiographic results in 76% of the patients.
