Total hip replacement for coxarthrosis secondary to congenital dysplasia and dislocation of the hip: long-term results

Abstract

tal hip replacements were performed with cement, without bone-grafting, in fifty-three patients who had congenital dysplasia and dislocation of the hip. Pre-operative! ^ the patients had had Crowe type-II, HI, or IV subluxation. Current information was avail-able for fifty-nine hips in forty-six patients after an average duration of follow-up of sixteen years (range, ten to twenty-one years). The average age of the pa-tients at the time of the operation was fifty-three years (range, twenty-three to seventy-three years). The aver-age Harris hip score at the most recent examination was 92 points (range, 61 to 100 points). Eight hips were revised. The reason for the revision was infection in two hips, fracture of the femoral stem in two, and loosening of the acetabular component in four. Th
