Forty-four patients with trochanter overgrowth (47 hips) ages 6 to 17 years underwent surgery. Trochanteric epiphysiodesis was performed in 13 patients (group A), distal transfer of the greater trochanter in 24 patients (26 hips; group B), and femoral neck lengthening osteotomy in 7 patients (8 hips; group C). The mean follow-up time was 8.3 years. Clinical results were evaluated by the hip score according to Merle d'Aubigné. Radiological parameters were evaluated by 2 of the authors. Each operative method led to an improvement of clinical symptoms. In group A, no significant changes in the radiological parameters could be found. Groups B and C showed significant improvements in the radiological parameters. However, no difference was found between these 2 groups.
