局部肌瓣转移和自体红骨髓注射治疗胫骨骨折骨不连

目的报告局部转移肌瓣和注射自体红骨髓治疗胫骨骨折不连接的效果。方法对15例伤后10～42个月,平均22个月仍不连接的胫骨骨折实施切开复位、带锁髓内钉固定、髂骨植骨和局部转移肌瓣覆盖,术后12～15d局部注射自体红骨髓治疗。结果随访表明所有病例骨折均得到连接,术后3～11个月(平均4.8个月)愈合,除2例术后出现切口皮缘小块坏死经换药愈合外,创口均一期愈合,没有发生感染和内固定失败。结论在稳固内固定和植骨以外,局部转移肌瓣和注射自体红骨髓治疗胫骨骨折不愈合能取得满意疗效。

Treatment of nonunion of tibial fractures with local muscle flap transfer and injection of autogenous bone marrow

Objective To report the treatment outcome of nonunion of tibial fractures with local muscle flap transfer and injection of autogenous bone marrow. Methods 15 patients who had suffered from nonunion of tibial fracture 10 to 42 (mean 22) months after the initial injury underwent open reduction, internal fixation with locking intramedullary nail, wound coverage with locally transferred muscle flap and injection of autogenous bone marrow into the fracture site 12 to 15 days after operation. Results The follow-ups revealed bone union in all the cases of this series with a mean healing time of 22 (3 to 11) months. Except for limited necrosis of the skin edge in 2 cases which healed after dressing changes, the wounds healed primarily in all the cases without infection and implant failure. Conclusion Besides stable internal fixation and bone graft, coverage of fracture site with locally transferred muscle flap and injection of autogenous bone marrow can be used to treat nonunion of tibial fractures with satisfactory results.
