Methods:9 patients including 8 male and 1 female were included in this study.2 patients suffered from both side of ANFH,5 were righe side and 2 were left side.X-ray,CT and MRI were performed before the surgery.4 hips were classified as ARCO stage 1,7 hips were stage 2.All the patients were treated as follows:the area of NFH and cystis degeneration were detected and bouche decompression was done through X-ray with C-arm,and the necrotic bone was cleared for the pathologic diagnosis under the monitoring of arthroscopy.And then the non-cell based tissue engineering bone, which was the complex of autologous red bone marrow and osteoinductice absorbing material containing BMP,was transplanted into the body.

本组9例，男性8例，女性1例；双侧股骨头坏死2例，右单侧股骨头坏死5例，左单侧股骨头坏死2例；术前均行X线摄片、CT、MRI 检查，ARCO分期：Ⅰ期4髋，Ⅱ期7髋；C型臂X线透视下行股骨头坏死区和囊性变区定位、髓芯减压，关节镜监视下，刮除坏死骨送病理；植入由自体红骨髓与含BMP的骨诱导活性材料复合成的非细胞型组织工程骨，并用空心钛钉支撑股骨头软骨下骨质。
