Abstract:
45?,poor containment of femoral head,narrow joint space,and non-successive Shenton's line.Following Crowe classification,there were 5 cases(5 hips) of grade II,and 3 cases(3 hips) of grade III.Preoperative Harris hip score was 50 points(range,44-62 points).Total hip arthroplasty was employed in each patient.Prosthesis was fixed by Cementless or cemented modes.Cementless fixation was applied in 6 hips and cemented fixation in 2 hips.Cementless prosthesis was used on the affected side in each patient.Replacement time,bleeding volume during surgery,hospital days post-surgery,Harris scores,and peri-operative complications were recorded.Simultaneously,post-surgery healing was observed.All 8 cases were followed up for an average period of 6 months.All patients exhibited well recovered joint function.No infection,sciatic nerve injury,dislocation of hip joint,fracture of femoral shaft,thrombosis of deep veins,or prosthesis loosening were found in any follow-up case.Six months after surgery,Harris hip score was 88 points(range,86-94 points).Radiographs taken at 3 months post-surgery displayed the bone union of surgical region.All these findings suggest that acetabular medial wall displacement osteotomy in total hip arthroplasty produces obvious early-and middle-stage effects in treatment of hip dysplasia.
