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

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.
