    Abstract:
    OBJECTIVE: To observe the osteogenesis of percutaneous autogenous bone marrow grafting in cicatricial bone defect, to seek a good method for treating fracture nonunion. METHODS: Eighteen rabbits were adopted in this study. 1 cm bone defect model was made in each side of radius, 6 weeks later, 2 ml autogenous bone marrow was injected in the right radial bone defect as experimental group, 2 ml autogenous peripheral blood in the left side as control group. X-ray features, histologic changes, Ca and P content in the site of bone defect were studied in various times. Also 15 patients were treated clinically for the nonunion fracture, the average time from nonunion to bone marrow grafting was 13 months. RESULTS: In experimental group, the increasing new bone tissue were observed in X-ray and histologic examination. While in control group, no osteogenesis was observed. Ca and P content of experimental group was higher than that of control group. For the 15 patients, 13 cases healed in 5-9 months, 2 cases failed. CONCLUSION: Percutaneous autogenous bone marrow grafting is capable of osteogenesis in the cicatricial bone defects. It can be used in nonunion cases which are not fit for operation of bone grafting because of poor condition of the skin.
