We studied factors contributing to residual deformity in patients with Perthes' disease who underwent additional surgery for residual deformity including a high trochanter and femoral shortening after Perthes' disease.<BR>We studied 34 hips. The mean age at the onset of Perthes' disease was 6.5 years, and the mean age at the time of additional surgery was 13.9 years. Additional surgery included: distal transfer of the greater trochanter in 13 hips, combined femoral lengthening and distal transfer of the greater trochanter in 20 hips, and femoral valgus osteotomy in one hip. According to the Catterall classification, 13 hips were in group 3, and 21 hips were in group 4. Major risk factors included lateral subluxation and metaphyseal cysts of head at risk signs, which were present in 94% of patients, respectively. When the final clinical results were evaluated according to the Stulberg classification, 6 hips were in class II, 24 hips were in class III, and 4 hips were in class IV.<BR>Residual deformity tended to occur in cases which were classified as group 3 and 4 according to the Catterall classification, and in which lateral subluxation or metaphyseal cyst were present, requiring additional surgery of the femur.
