摘　　要：目的探讨骨折复位固定系统的安全性、有效性和临床应用价值。方法描述骨折复位固定系统组件克氏针限位器和克氏针导向锁紧器的设计和应用;6个医生根据手感或应用克氏针限位器在合成骨中植入克氏针,测量克氏针穿出骨的长度;克氏针导向锁紧器配合锁定板及2根直径1.5 mm克氏针、2根直径1.5 mm克氏针和2根直径2.0 mm克氏针固定合成骨构建的骨折模型,测量结构的失效扭矩。结果克氏针限位器降低了克氏针穿出骨的长度,差异有统计学意义(P<0.001),克氏针导向锁紧器配合锁定板及2根直径1.5 mm克氏针固定骨折失效扭矩高于2根直径1.5 mm克氏针和2根直径2.0 mm克氏针固定骨折(P<0.05)。结论骨折复位固定系统是提供复位和固定骨折、判断和优化锁定板螺钉位置及保护骨折块血运的新技术。Objective To investigate the safety,efficacy,and clinical value of a fracture reduction and fixation system.Methods The design and application of components[Kirschner wire(K-wire)limiter and K-wire guiding locking device]of the fracture reduction and fixation system were described.Six surgeons implanted K-wires into synthetic bones using the K-wire limiter or by perception respectively,and the length of K-wire protrusion was assessed.K-wire guiding locking device combined with locking plates and two 1.5 mm K-wires,two 1.5 mm K-wires,as well as two 2.0 mm K-wires were used to fix a fracture model constructed by synthetic bones,and the torque at failure was measured.Results The K-wire limiter reduced the length of K-wire protrusion(P<0.001).The failure torque of fractures fixed by K-wire guiding locking device with locking plates and two 1.5 mm K-wires was larger than those fixed with two 1.5 mm K-wires and two 2.0 mm K-wires(P<0.05).Conclusion The fracture reduction and fixation system offers a new technique for reducing and reconstructing fractures,assessing and optimizing the position of locking plate screws,as well as protecting the blood supply of fractures.
