The Author has developed a modified intramedullary nail for the stabilisation of fractures in the subtrochanteric and proximal one-third of the femur. Due to its three tapered fins the rod fits well into the funnel-like medullary cavity of the proximal femur preventing varus or rotational displacement of the proximal fragment. This method has been applied in 16 cases. Its particular advantages are the chance to perform the operation closed, a short operating time and period in hospital, early weight bearing and a simple surgical technique without the need for special instrumentation, requiring little radiographic exposure during surgery. The ideal and relative indications for the application of the technique are discussed. Biomechanical tests have confirmed that the finned medullary nail is the most stable method of fixation of the fractures when compared with other alternative devices.
作者研发了一种改良型髓内钉，用于稳定股骨转子下和近端三分之一处的骨折。由于其具有三个逐渐变细的鳍状物，该髓内钉能很好地适配股骨近端漏斗状的髓腔，防止近端骨折块内翻或旋转移位。此方法已应用于16例病例。其特别优点包括能够进行闭合手术、手术时间和住院时间短、可早期负重以及手术技术简单，无需特殊器械，手术期间所需的X线暴露少。文中还讨论了该技术的理想适应证和相对适应证。生物力学测试已证实，与其他替代装置相比，带鳍髓内钉是固定骨折最稳定的方法。
