股骨远端骨折采用股骨髁上交锁髓内钉固定的生物力学研究与临床应用

目的：对股骨远端骨折不同内固定方法进行定量生物力学评价，为临床治疗提供理论依据。方法；从理论和实验上对股骨Y形骨折，应用三种不同内固定方法加以固定，进行实验应力分析。结果：发现在受同等载荷条件下，髁上交锁髓内钉固定方法最佳，而采用加压钢板固定的股骨髁强刚度较度（P＜0．05）。结论：采用股骨髁上交锁髓内钉固定方法优于其它内固定方法，值得临床推广应用。

BIOMECHANICAL STUDY AND CLINICAL APPLICATION OF FIXING DISTAL FEMORAL FRACTURE USING INTRAMEDULLARY SUPRACONDYLAR NAIL (LMSC)

Objective Quantitative biomechanical compairson of different internal fixation methods for distal femoral fractures provides theoretical basis for clinic curing. Method Performing theoretical and experimental stress analysis for fixing Y type femora fracture by using three different internal fixation methods. Results Under the same load condition Intramedullary supracondylar nail method is the best while for comprssed plate method the femoral condyle strength and origidity is worse (P<0.05). Conclusion Intramedullary Supracondylar nail Method is the best method among different internal fixation methods. It deserves to be put into application and populatization.
