目的 探讨经皮自体骨髓移植治疗胫骨骨折不愈合的疗效。方法 1996年3月－2000年6月，用自体骨髓移植治疗胫骨骨不连患者56例。采用抽取自身红骨髓，在X线透视下用一枚骨穿针刺入骨不连部位注射，术后加压包扎并选用合适的固定材料，每月1次，共需2－3次。结果 56例全部获得随访，时间为4个月－4年2个月，平均2．8年。骨折愈合53例。X线片示：骨折线消失，有大量边疆骨痂形成，未愈合3例。结论 自体骨髓移植在骨不连部位有成骨作用，取材容易，操作简便，疗效满意，有临床应用价值。

AUTOGENOUS BONE MARROW GRAFT FOR THE MANAGEMENT OF NONUNION OF TIBIA

Objective　To investigate the effect of percutaneous bone marrow graft for the management of nonunion of tibia. Methods　From March 1996 to June 2000, 56 cases with nonunion of tibia were treated by autogenous bone marrow graft. Among them, there were 38 males and 18 females, aged from 19 to 72 years. A marrow needle was inserted into the site of the nonunion under the X-ray, the autogenous bone marrow was injected into the site of nonunion. Compression bandage and appropriate immobilization material were applied after operation. This procedure was repeated every month, 2 or 3 times was needed. Results　56 patients were followed-up for 4 months to 4 years and 2 months, averaged 2.8 years. Fracture healed in 53 cases and X-ray displayed fracture line disappeared and a great deal of continuous callus formed,and nonunion in 3 cases. Conclusion　Percutaneous autogenous bone marrow graft can play a role in osteogenesis at the site of nonunion. It is easy to aspirate bone marrow and the operation is simple. It has clinical application value for the satisfactory effect.
