The Gamma AP (Asia-Pacific) locking nail (GAPN) is a modification of the standard Gamma locking nail made especially for use in Oriental patients. We made a randomised prospective comparison of the compression hip screw (CHS) and the Gamma AP locking nail for the internal fixation of 60 intertrochanteric fractures of the hip in elderly patients by comparing perioperative details and analysing the radiographic and clinical results. The operation time for the GAPN group was shorter than for the CHS group and the intraoperative blood loss was lower. The Gamma AP nail enabled earlier mobilisation. We found no significant difference in the time to union and the length of sliding of the lag screw between the two groups. The decrease in the neck shaft angle in the Gamma nail group was significantly smaller than in the CHS patients. There were no significant mechanical complications, such as fracture of the femoral shaft or failure of fixation in the Gamma nail group. On the basis of our observations we conclude that the Gamma AP locking nail is more efficient than the CHS in the treatment of intertrochanteric fractures in geriatric patients.
Gamma AP（亚太区）锁定钉（GAPN）是对标准Gamma锁定钉进行改良后专门用于东方患者的产品。我们通过比较围手术期细节并分析影像学和临床结果，对60例老年患者的股骨转子间骨折采用加压髋螺钉（CHS）和Gamma AP锁定钉进行内固定治疗进行了随机前瞻性比较。GAPN组的手术时间比CHS组短，术中失血量也更少。Gamma AP钉能使患者更早活动。我们发现两组之间在骨折愈合时间和拉力螺钉滑动长度方面无显著差异。Gamma钉组的颈干角减小明显小于CHS患者。Gamma钉组没有出现明显的机械并发症，如股骨干骨折或内固定失败。基于我们的观察，我们得出结论，在治疗老年患者股骨转子间骨折方面，Gamma AP锁定钉比CHS更有效。
