The DHS-implant system is a technically simple and widely used operative treatment modality for pertrochanteric fractures of the femur. In unstable 4-part fractures rotation of the head and neck fragment around the lag screw and significant impaction might lead to lateralisation of the greater trochanter and therefore to marked shortening. To prevent these effects we treated 17 patients with 4-part fractures with a prototype of a modular trochanteric DHS buttress plate. With this additional implant lateralisation of the greater trochanter could be prevented in all cases. This also leads to a limitation of telescoping, with less shortening even with immediate full weight bearing.
动力髋螺钉（DHS）植入系统是一种技术上简单且广泛应用于股骨转子间骨折的手术治疗方式。在不稳定的四部分骨折中，头颈骨折块围绕拉力螺钉旋转以及明显的嵌插可能导致大转子向外移位，进而导致明显的短缩。为防止这些影响，我们使用模块化转子DHS支撑钢板的原型治疗了17例四部分骨折患者。通过这种额外的植入物，在所有病例中均能防止大转子向外移位。这也限制了缩短，即使立即完全负重，短缩程度也较小。
