联合应用带锁髓内钉及西脉TiNi记忆合金骨卡环治疗股骨干粉碎骨折

目的 观察联合应用带锁髓内钉及西脉TiNi记忆合金骨卡环治疗股骨干粉碎骨折的疗效。方法 本组股骨干粉碎骨折35例，均为AO分型中的B型和C型。其中B型25例，C型10例。全部病例采用开放复位带锁髓内钉加记忆合金骨卡环内固定治疗，5例行植骨。结果 经12～24个月随访(平均18．5个月)，除1例因骨卡环脱落而行手术外，全部病例骨折二期愈合。术后18～24个月取出带锁髓内钉。按Klemm功能恢复分级标准，总体优良率98．2％。结论 带锁髓内钉加记忆合金骨卡环内固定治疗股骨干粉碎骨折可互相取长补短、稳定固定，是一种可行有效的方法：

Treatment of comminuted femoral shaft fractures with combination of intramedullary interlocking nail and shape memory sawtooth-arm block hoop internal fixator

Objective To observe the clinical outcomes of the treatment of comminuted femoral shaft fractures with combination of intramedullary interlocking nail and shape memory sawtooth-arm block hoop internal fixator. Methods 35 cases of comminuted femoral shaft fractures were treated with combined use of intramedullary interlocking nail and shape memory sawtooth-arm block hoop internal fixator. Of the 35 cases, 25 were type B and 10 type C according to AO classification. 1 case had bilateral femoral shaft fracture of type B. Results All the fractures were followed up for 12 to 24 months (averaging 18.5 months). By second attention, all the fractures healed except 1 case who had to undergo secondary surgery because his shape memory sawtooth-arm block hoop internal fixator had dropped. The intramedullary interlocking nails were taken out 18 to 24 months postoperatively. The excellent rate was 98.2?cording to Klemm grading system. Conclusion In treatment of comminuted femoral shaft fractures, the combined use of intramedullary interlocking nail and shape memory sawtooth-arm block hoop internal fixator can take advantages of the 2 devices so as to secure anatomic reduction and reliable fixation.
