Abstract
Total hip replacement for adults with severe acetabular dysplasia presents a difficult problem because deficient bone stock and soft tissue contractures usually prevent sitting at the normal anatomic level. The rationales of high hip center are due to high failure rate of bulk structural weight bearing graft, good short-term result of hemispherical cementless acetabular component in revision surgery, high hip center but not lateral which does not adversely affect the biomechanics of the hip, and intimate apposition with viable host bone. We represented the short-term results of 21 total hip replacements with proximal placement of the acetabular cup than the anatomical position that is normally used. The mean duration of follow up was 18 months(range, 12-58 months) and the mean age of the patient was fifty-one years(range, thirty to sixty-seven years). Most of these hips had a major deficiency or defect of the acetabular bone stock. They had an aver- age Harris hip score of 47 points preoperatively and 90 points postoperatively. Roentgenographic measurements showed that the mean change in the height of the center of the hip postoperatively was only +6.6 millimeters and the mean change of horizontal location of them was 10 millimeters medial to the preoperative position. Postoperative complications included calcar fracture(1 case), trochanteric bursitis(1 case), postop- erative dislocation(1 case) and one case of radiological loosening of the acetabular component. The center of the hip in THR is not a crucial parameter with regard to the long-term stability of acetabular component, so our recommendation is to place the acetabular component at a more proximal but not lateral position if strong bone stock is available. But future studies of high hip center need to address femoral component longevity.
