[Treatment of osteonecrosis of the femoral head with implantation of autologous bone-marrow mononuclear cells].

Idiopathic osteonecrosis of the femoral head commonly develops during adolescence and in the prime of adulthood. In Japan, joint-preserving procedures such as transtrochanteric rotational osteotomy, femoral varus osteotomy and vascularized bone grafting are often the surgical treatments of choice. However, the results of these procedures are not necessarily satisfactory. These procedures force patients to endure longer waits for their entire treatment. In addition, it is often difficult for surgeons to choose the appropriate treatment, especially in patients who have bilateral extensive osteonecrosis. We reported transplantation of bone marrow mononuclear cells for osteonecrosis of the femoral head and short-term results.
