Sickle cell disease causes osteonecrosis (20% to 50% of patients) and collapse of the femoral head that result in secondary osteoarthritis. Total hip arthroplasty (THA) is a valid alternative for these patients. We define the difficulties that can be encountered when undertaking THA in sickle cell disease patients and give advice on how to deal with these technically demanding procedures. We undertook total hip arthroplasty procedures on 12 patients (4 females and 8 males) with osteonecrosis of the femoral head. Two bilateral prostheses were performed. We had only one type of stem, only one type of acetabular cup and only 28 mm cobalt chrome heads. The procedures were performed through either an anterior or a direct lateral approach. The average size of the Cup was 46 (Versafit, Medacta), the average size of the femoral stem was 0 (Amistem, Medacta), the most used size of the modular head was a S. Standard stem that was used in nine patients, while three patients received a lateralizing stem. Three patients had periprosthetic fracture, treated by cerclage. Total hip replacement is an excellent alternative for patients with osteonecrosis from sickle cell disease. The preparation of the acetabulum and the femur is difficult and requires attention, time and appropriate equipment.
