Comparing the Outcomes of Limited and Classic Approach for Periacetabular Osteotomy in Surgical Treatment of Hip Dysplasia

Backgrounds and Periacetabular Osteotomy (PAO) is a well established method in treating the hip dysplasia in adults. Despite of the lack of information about the final outcome of the PAO operation، this procedure is frequently used. The aim of this study was to evaluate the results of PAO operation among patients with severe dysplasia of the hip joint. In a simple randomized clinical trial study، 20 patients were divided into two groups and were treated with classical and limited surgical osteotomy. The patients were followed for six months. The mean age of study was 26/7 years. The classical and limited techniques were performed on 11 and 9 years old cases، respectively. The amount of bleeding in the classical and limited methods were 661 ml and 477 ml respectively (P =0. 001). The two groups did not differed in term of the hip functional joint. There was no difference of pain controlling between the two methods. The periacetabular osteotomy alone was successful for treatment in severe hips dysplastic. Rectus femuris tendon junction maintains had no effect on treatment results; both methods were successful in creating adequate coverage of the femoral head.
