Thirty-two consecutive subtrochanteric femur fractures were treated using the 95 degree dynamic condylar screw between 1982 and 1985. All fractures were classified according to the radiographic criteria of Seinsheimer. Twenty-two patients were available for follow-up study, with an average time of 23.8 months. Functional results were rated using a new traumatic hip score rating system. The overall union rate was 77.3% (17/22), with functional results rated as excellent or good in 68% (15/22). All five technical failures were associated with extensive bony comminution. Four of these failures were not bone grafted. There were no cases of screw penetration of the femoral head or neck. The indications for the use of this device include transverse, short, and long oblique subtrochanteric fractures, with or without lesser trochanteric avulsion. When excessive comminution exists, this device should not be employed.
1982年至1985年间，采用95度动力髁螺钉治疗了32例连续性股骨转子下骨折。所有骨折均根据Seinsheimer的影像学标准进行分类。22例患者可供随访研究，平均随访时间为23.8个月。功能结果采用一种新的创伤性髋关节评分系统进行评定。总体愈合率为77.3%（17/22），68%（15/22）的功能结果评定为优或良。所有5例技术失败均与广泛的骨粉碎有关。其中4例失败病例未进行植骨。没有螺钉穿入股骨头或颈部的病例。使用该器械的适应证包括横形、短斜形和长斜形股骨转子下骨折，伴或不伴小转子撕脱。当存在过度粉碎时，不应使用该器械。
