A residual postoperative fracture gap between major bone fragments following intramedullary nailing of long-bone fractures is recognised as one of the major risk factors for delayed union and non-union. The most common method for reducing a fracture gap after nail insertion is through application of the backstroke technique. We introduce forward-striking as a new and simple technique that can be used to reduce fracture gaps during cephalomedullary or intramedullary nailing.
The forward-striking technique was used in 20 patients with subtrochanteric or femoral shaft fractures and three patients with tibial shaft fractures who underwent cephalomedullary or intramedullary nailing at two university teaching hospitals between February 2013 and March 2014.
Bone union was achieved in all cases, with a mean time of 5.7 months (range, 3-9 months). No major complications, including, non-union, implant failure, or infection, were encountered during the follow-up period.
A forward-striking technique is simple, convenient, and highly efficient in terms of reducing fracture gaps during cephalomedullary or intramedullary nailing. The advantage of this technique is that it carries no risk of deforming the proximal interlocking screw, prevents excessive protrusion of the nail, and enables the lag screw to be placed into the optimal lag screw position relative to the femoral head at the time of cephalomedullary nailing. The forward-striking technique is particularly useful if no compression screw system is available.
长骨骨折髓内钉固定后,主要骨块之间残留的术后骨折间隙被认为是延迟愈合和不愈合的主要危险因素之一。插入髓内钉后减小骨折间隙最常用的方法是应用回抽技术。我们介绍一种新的简单技术——前击技术,可用于在股骨近端髓内钉或髓内钉固定过程中减小骨折间隙。
2013年2月至2014年3月期间,两所大学教学医院对20例转子下或股骨干骨折患者以及3例胫骨干骨折患者采用前击技术进行股骨近端髓内钉或髓内钉固定。
所有病例均实现骨愈合,平均时间为5.7个月(范围3 - 9个月)。随访期间未出现包括不愈合、植入物失败或感染等重大并发症。
前击技术在股骨近端髓内钉或髓内钉固定过程中减小骨折间隙方面简单、方便且高效。该技术的优点是不会使近端锁定螺钉变形,防止髓内钉过度突出,并能在股骨近端髓内钉固定时将拉力螺钉置于相对于股骨头的最佳拉力螺钉位置。如果没有加压螺钉系统,前击技术特别有用。
