摘　　要：目的　探讨AO动力髁螺钉 (DCS)治疗股骨转子下长节段粉碎性骨折的效果。方法　对 2 1例股骨转子下长节段粉碎性骨折患者采用间接复位、DCS内固定。结果　随访 10～ 36个月 ,平均 2 3个月 ,所有病例均骨性愈合 ,平均愈合时间 4个月。无一例发生钢板螺钉松动、断裂、骨不连等并发症。功能评定 :优 17例 ,良 4例。结论　DCS特别适用于治疗转子下粉碎性骨折 ,符合髋部生物力学要求 ,能达到良好的骨折复位、坚强的固定 ,可早期活动关节及功能锻炼 。Objective To investigate AO dynamic condylar screw(DCS) in the treatment of long-segmented and comminuted subtrochanteric fracture. Methods 21 cases with long-segmented and comminuted subtrochanteric fracture were treated with indirect reduction and AO DCS. Results The follow-up ranged from 10 to 36 months with an average of 23 months. Complete union were found in all cases. The union time was 4 months on average. No plate and screw looseness, breakage or nonunion was found. The function recovery was excellent in 17 cases and good in 4. Conclusion DCS is especially suitable for complex subtrochanteric fractures and tally with the biomechanical requirements. It has obvious advantages of good reduction and has a reliable fixation, early rehabilitation and high healing rate. All these are up to the biomechanic principles.
