Avascular Necrosis of Femur Head
Conditions
Brief summary
The purpose of this study is to compare the efficacy of autologous enriched bone marrow cell implantation combined with core decompression to single core decompression for the treatment of avascular necrosis of femoral head.
Interventions
minimal surgical invention to drill a core to the femoral head to release pressure
Patients are subjected to bone marrow aspiration from the anterior iliac crest. Mononuclear cells are enriched from patients' bone marrow by centrifuge, which are grafted with autologous cortical bone and implanted to the necrotic zone of the femoral head.
