Bending burdening of stable and unstable per- and subtrochanteral fractures after osteosynthesis with Y-nails (Küntscher), Ender-nails, 130 degrees and 95 degrees angled plates of the AO were tested in a comparative experimental study. The unstable fractures were also tested after treatment with osteosynthesis and additional application of bone cement in the artificial defect. The essential results were as follows: in the group of stable pertrochanteral fractures the Ender-nails bear in the mean 147 kp, the 130 degrees angle plate 200 kp. In the fracture-group with lacking medial support a highly burdening osteosynthesis could only be achieved by filling up the defects with bone cement. The 95 degrees-angled plate-osteosynthesis combined with bone cement bearing more than 300 kp was superior to the other procedures in the unstable per- and subtrochanteral fractures. In our investigation the stabilizing forces of muscles and fascia have not been taken into consideration.
在一项对比实验研究中，对采用Y形钉（昆scher钉）、恩德勒钉、AO 130度和95度角钢板进行接骨术后稳定型和不稳定型转子周围及转子下骨折的弯曲负荷情况进行了测试。对于不稳定型骨折，在接骨术治疗后并在人工缺损处额外应用骨水泥后也进行了测试。主要结果如下：在稳定型转子周围骨折组中，恩德勒钉平均承受147千克力，130度角钢板承受200千克力。在缺乏内侧支撑的骨折组中，只有通过用骨水泥填充缺损才能实现高负荷接骨术。在不稳定型转子周围及转子下骨折中，95度角钢板接骨术联合骨水泥承受超过300千克力，优于其他方法。在我们的研究中，未考虑肌肉和筋膜的稳定力。
