Fourteen different commonly used osteosyntheses for unstable pertrochanteric fractures with medial bone defect were systematically analysed concerning their stability. For this purpose the deformation and the maximum stability of 36 surgically stabilized fractured femora from donor corpses were tested. For the experimental investigations the hip force FM was not only induced on the femora in orthograde direction but also in an inclination of 45 degrees of anteflexion of the femur as it appears during walking up stairs. As a result, all tested osteosyntheses had significantly lower maximum stability and greater deformation if the hip force was induced on the anteflexed femur in contrast to orthograde loading. From our analysis clinically important conclusions can be drawn concerning the operation techniques and the post-operative after treatment concepts.
对14种治疗伴有内侧骨缺损的不稳定转子间骨折常用的骨合成方法的稳定性进行了系统分析。为此，对36具供体尸体手术固定的股骨骨折标本的变形情况和最大稳定性进行了测试。在实验研究中，不仅沿股骨的顺行方向施加髋部力FM，还在股骨前倾45度（如上楼时出现的情况）的倾斜状态下施加髋部力FM。结果表明，与顺行加载相比，当在股骨前倾状态下施加髋部力时，所有测试的骨合成方法的最大稳定性均显著降低，变形程度更大。通过我们的分析，可以得出关于手术技术和术后治疗理念的重要临床结论。
