Injuries of unstable pertrochanteric fractures of the upper femur represent a contingent with high multi-morbidity at highest average age. The only successful procedures within biologically set boundaries, would be those of an early and weight-bearing resistive osteo-synthesis. Starting in 1979 till the middle of 1982, we treated 70 unstable pertrochanteric fractures out of 350 proximal femur fractures, with this compression hip screw. Because of its underlying bio-mechanical principle, its advantageous operative handling, as well as high durability of the material used, this version of an osteosynthesis showed few complications. We found neither head penetration and pseudoarthrosis, nor did we find any implant bending and breaking so far. Although averaging almost 80 years, 63% of our patients could be released after hospitalization for an average of 39 days, leaving at full mobility. The set goal of an early weight-bearing with elderly patients was fully achieved by means of this version of osteo-synthesis, since dynamic compression of even comminuted fracture zones permitted a statically sound and unhindered possibility at weight-bearing.
股骨上段不稳定型转子间骨折损伤在平均年龄最大的人群中具有高合并症发生率。在生物学设定的范围内，唯一成功的手术方法是早期抗负重骨固定术。从1979年到1982年年中，我们用这种加压髋螺钉治疗了350例股骨近端骨折中的70例不稳定型转子间骨折。由于其潜在的生物力学原理、有利的手术操作以及所用材料的高耐用性，这种骨固定术并发症很少。我们既未发现股骨头穿透和假关节形成，到目前也未发现任何植入物弯曲和断裂。尽管患者平均年龄近80岁，但63%的患者在平均住院39天后可以出院，且活动自如。通过这种骨固定术，老年患者早期负重的既定目标得以完全实现，因为即使是粉碎骨折区域的动态加压也能在负重时提供静态稳固且不受阻碍的可能性。
