ABSTRACT
Background: Elimination of abnormally high joint-loading resulting in excessive contact stresses may prevent or reduce the onset of osteoarthrosis in a dysplastic hip. A number of periacetabular osteotomies have been shown to be effective in restoring normal hip-joint mechanics. We treat acetabular dysplasia with a periacetabular osteotomy performed through a modified Oilier transtrochanteric approach. In this report, we describe the operative technique and the clinical and radiographic results. Methods: Thirty-six patients (thirty-eight hips) in whom a painful dysplastic hip had been treated with a periacetabular osteotomy between March 1991 and June 1999 were included in the study. There were thirty-five female patients and one male patient with a mean age (and standard deviation) at the operation of 29.42 ± 9.1 years. The technique utilizes a u-shaped skin incision, and a routine osteotomy of the greater trochanter with distal transfer if needed, and allows excellent visualization enabling the surgeon to perform the periacetabular osteotomy without penetrating the joint. Results: At a mean of five years and six months postoperatively, the mean modified Harris hip score had improved from 59.1 ± 15.8 points preoperatively to 87.97 ± 14.3 points. Radiographically, the degree of osteoarthrosis had decreased in eleven hips, remained unchanged in twenty-four, and worsened in three. The mean anterior center-edge angle had increased from 22.0° ± 12.9° to 36.1° ± 12.3°, the mean lateral center-edge angle had increased from -2.7° ± 14.4° to 26.6° ± 14.1°, the mean acetabular index angle had improved from 23.4° ± 6.6° to 12.7° ± 4.6°, and the mean acetabular head index had increased from 48.2% ± 12.7% to 73.1% ± 16.0%. The Shenton line was restored in eleven hips. Thirty patients (thirty-two hips; 84%) had a satisfactory result. A poor...
