OBJECTIVETo study advantages of Pemberton acetabuloplasty for the treatment of developmental dislocation of hip joint.

METHODSAmong 106 children (116 hips) with development dislocation of hip joint treated by Pemberton acetabuloplasty, 19 patients (29 hips) were boy, and 87 patients (87 hips) were girl, 46 hips were left side, 50 hips were right side and 20 hips were double side, ranging in age from 18 months to 13 years, with an average of 7 years and 3 months. All the 116 hips were treated with Pemberton acetabuloplasty, or "complete operation", which included the cutting of adductor and iliopsoas, Pemberton acetabuloplasty combined with subtrochanteric femoral shortening and rotation osteotomy. Among the hips, 95 hips were treated with simple Pemberton acetabuloplasty, and the other 21 hips were treated with complete operation. All the patients with bilateral developmental dislocation of hip joint were performed the operation at one side firstly, and one year later the other side were performed and the plate fixation in the first operation were removed.

RESULTSAll the patients were followed-up ranging from 2 to 10 years, with an average of 6 years. According to Muller and Seddon's evaluation criteria, 67 hips got an excellent result, 34 good, 10 fair and 5 bad, the excellent and good rate was 87%.

CONCLUSIONPemberton acetabuloplasty is suitable for the treatment of developmental dislocation of hip joint in children at different ages, and the therapeutic effects are good.
