OBJECTIVE: To evaluate the results of surgical treatment of Developmental Dysplasia of the Hip (DDH) treated in the walking age. METHODS: We evaluated 33 hips in 30 patients operated between November of 1992 and September of 1997. The mean age was 4 years and 5 months at surgical period and the mean age at the last evaluation was 11 years and 7 months. The mean follow up time was 10 years and 2 months. We performed femoral shortening, open reduction and pelvic osteotomy (Salter or Chiari). Radiographic assessment considered: acetabular index; acetabular angle; Shenton's line; Hilgenreiner's line; the c/b, c/h, acetabulum-center and acetabulum-head ratios; the width of the triradiate cartilage; the trochanter and femoral head relationship; femoral head sphericity; Wiberg angle; avascular necrosis and leg length discrepancy. These parameters were measured and compared in pre-operative, early and late post-operative period. RESULTS: After statistical analysis we observed a significant decrease in these parameters from pre-operative period to immediate post-operative period (p=0.0001) and those have not changed between the immediate post-operative period and late post-operative period (p=0.5958). CONCLUSION: By the classification used we observed 23 (69.70%) good, 5 (15.15%) regular and 5 (15.15%) bad results. None of these radiographic parameters were relevant to predicting final results.
