Intramedullary nails, long and short, are widely used for fixation of trochanteric femur fractures. In theory, long nails may be able to protect the entire length of the femur from a future periprosthetic fracture, providing that the nail spans the length of the entire femoral canal. The described technique for long nail insertion calls for the use of an intramedullary guidewire and depth gauge for premeasurement of the length of the canal, as well as the use of a reamer. However, compared with short nails, this technique may add cost, operating time, and blood loss. We describe a safe technique for long nail measurement that reliably spans the length of the femur while potentially reducing surgical cost, time, and blood loss. We also describe 21 cases in which the technique was applied.
长型和短型髓内钉广泛用于股骨转子间骨折的固定。理论上，只要髓内钉跨越整个股骨髓腔的长度，长型髓内钉或许能够保护股骨全长以防未来发生假体周围骨折。所述的长型髓内钉插入技术需要使用髓内导丝和深度测量仪来预先测量髓腔长度，以及使用扩髓器。然而，与短型髓内钉相比，该技术可能会增加成本、手术时间和失血量。我们描述了一种安全的长型髓内钉测量技术，该技术能够可靠地跨越股骨长度，同时有可能降低手术成本、手术时间和失血量。我们还描述了应用该技术的21例病例。
