The results of arthroplasty of the hip and other surgical procedures that
were performed in nine patients who had sickle-cell disease or sickle-cell
trait and osteonecrosis of the femoral head were not very satisfactory.
After an average duration of follow-up of 6.5 years (range, two to 25.7
years), the complications were many and severe. Of eight arthroplasties
that were done for replacement of a joint, five required early revision or
excision: two, because of mechanical loosening; two, because of sepsis; and
one, due to a fracture of the prosthetic stem. There was excessive
perioperative blood loss, prolonged hospitalization, and medical or
surgical complications in all patients, including the three who had
sickle-cell trait and only slight manifestations of systemic disease. A
survivorship analysis of this series indicated that a failure rate of 50
per cent could be expected by 5.4 years postoperatively.
