A total of 125 patients with pertrochanteric or subtrochanteric fractures were treated by means of internal fixation with dynamic hip screws (DHS), and 77 were reviewed both clinically and radiologically after an average period of 29 months (6-69 months). This study included group A 2 fractures (with a large lesser trochanter fragment) and group A 3 fractures (pertrochanteric region) according to the ASIF classification, and also fractures of the proximal femoral shaft. With proper surgical technique only 5 cases of early infection (4%) were recorded. Early mobilization of these patients was possible owing to stable implants. There were 7 patients (5.6%) who died while still in hospital. Of the 77 patients in whom follow-up was possible, 76 had results falling in the very good or good categories according to the Merle d'Aubigné scheme. During this follow-up period 3 cases of implant fracture were encountered. In all other cases progression to bone union was uneventful. These results show that the use of DHS is a reliable method of stabilizing unstable pertrochanteric and subtrochanteric fractures.
共有125例转子间或转子下骨折患者接受了动力髋螺钉（DHS）内固定治疗，其中77例在平均29个月（6 - 69个月）后接受了临床和影像学复查。本研究包括根据AO/ASIF分类的A2型骨折（小转子大骨折块）和A3型骨折（转子间区域），以及股骨干近端骨折。采用恰当的手术技术，仅记录到5例早期感染（4%）。由于植入物稳定，这些患者能够早期活动。有7例患者（5.6%）在住院期间死亡。在77例能够进行随访的患者中，根据Merle d'Aubigné评分系统，76例结果为优或良。在该随访期间，遇到3例植入物断裂。在所有其他病例中，骨折顺利愈合。这些结果表明，使用DHS是稳定不稳定转子间和转子下骨折的可靠方法。
