摘　　要：目的探讨自行研制的新型双翼股骨干骨折复位固定器的生物力学性能及临床应用效果。方法利用试验应力分析方法,测定该复位器强度、刚度及抗扭转力,并对临床应用的158例病例进行应用分析。结果该内固定器强度及刚度均达到生物力学要求,术中复位时间较前缩短,158例患者随访6～23个月,无骨延迟愈合及不愈合者。结论双翼股骨干骨折复位固定器复位简便、固定可靠,可大大减少劳动强度、节约手术时间且副损伤小,有利于骨折愈合。Objective To explore the biomechanic properti es and clinical application of the se lf-designed bilateral reduction-fixator in tre atment of femoral shaft fractures.Methods Biomechanical tests were done to de-termine the strength,rigidity and a nti-torque of the self-designed bilateral reduction-fixator.It was ap plied in 158clinical cases.Results The strength and rigidity of the fixator could satisfy the biomechanic re quirements.The perioperative reduction time was sh ortened.The follow-ups of 6to 23mon ths showed that the 158cases experie nced no delayed bone union or nonunion.Conclusion The fixator can provide simple reduction and reliable fixation,greatly reduce the labor intensity,shorten the operation time,and resu lt in fewer secondary injuries.[
