We reviewed our experience with total hip replacement for coxarthrosis
due to Paget's disease. The clinical and radiographic results in twenty-one
patients who had a total hip replacement between October 1972 and February
1982 were analyzed. The ages of the patients averaged 68.6 years (range,
fifty-seven to eighty years) and there were twelve women and nine men. The
follow-up averaged five years and two months (range, two years to eleven
years and four months). A good or excellent result was achieved in eighteen
patients. Of the other three patients, two required a revision operation at
two and one-half and five years postoperatively for symptomatic mechanical
loosening of the femoral component. The remaining patient had a fair result
because of activity of the Paget's disease. Special problems that we
encountered included varus deformity of the proximal end of the femur
predisposing to varus placement of the femoral component, protrusio
acetabuli, increased blood loss, sclerotic bone that made reaming
difficult, and heterotopic ossification.
