October 3Treatment of Osteonecrosis With Autologous Bone Marrow Grafting

Hip Pain

Core decompression with bone graft is used fre- quently in the treatment of osteonecrosis of the femoral head. Many different techniques have been described. In the current series, grafting was done with autologous bone marrow ob- tained from the iliac crest of patients operated on for osteonecrosis of the hip. The results of a prospective study of 189 hips in 116 patients treated with core decompression and autologous bone marrow grafting are reported. Patients were followed up from 5 to 10 years. The out- come was determined by the changes in the Har- ris hip score, by progression in radiographic stages, and by the need for hip replacement. The bone marrow was harvested with the patient un- der general anesthesia. The usual sites were the anterior iliac crests. The aspirated marrow was reduced in volume by concentration and in- jected into the femoral head after core decom- pression with a small trocar.
