We have prospectively compared the fixation of 100 intertrochanteric fractures of the proximal femur in elderly patients with random use of either a Dynamic Hip Screw (DHS) or a new intramedullary device, the Gamma nail. We found no difference in operating time, blood loss, wound complications, stay in hospital, place of eventual discharge, or the patients' mobility at final review. There was no difference in failure of proximal fixation: cut-out occurred in three cases with the DHS, and twice with the Gamma nail. However, in four cases fracture of the femur occurred close to the Gamma nail, requiring further major surgery. In the absence of these complications, union was seen by six months in both groups.
我们前瞻性地比较了在老年患者中随机使用动力髋螺钉（DHS）或新型髓内装置Gamma钉对100例股骨近端粗隆间骨折的固定效果。我们发现，在手术时间、失血量、伤口并发症、住院时间、最终出院地点或末次复查时患者的活动能力方面，二者并无差异。近端固定失败情况也无差异：DHS组有3例出现内固定物穿出，Gamma钉组有2例。然而，有4例患者的股骨在靠近Gamma钉处发生骨折，需要进一步进行大手术。在没有这些并发症的情况下，两组患者均在6个月时实现骨折愈合。
