Treatment of osteonecrosis of the femoral head using autologous cultured osteoblasts: a case report

Abstract

Abstract Introduction Osteonecrosis of the femoral head is a progressive disease that leads to femoral head collapse and osteoarthritis. Our goal in treating osteonecrosis is to preserve, not to replace, the femoral head. Case presentation We present the case of a patient with bilateral osteonecrosis of the femoral head treated with autologous cultured osteoblast injection. Conclusion Although our experience is limited to one patient, autologous cultured osteoblast transplantation appears to be effective for treating the osteonecrosis of femoral head.
