Intramedullary nails are currently the most commonly used device for the fixation of intertrochanteric hip fractures. An initial threaded guidewire is used for localizing the site of entry and determining the final position of the fixation device. Hardware failure with guidewire breakage can complicate the procedure and lead to unplanned challenges for the surgeon. Predisposing mechanical properties of the hardware, along with technical surgical errors may lead to inadvertent breakage or migration of guidewires. The authors report a case of initial threaded starting guidewire migration into the femoral intramedullary canal with subsequent impaction into the distal femoral subchondral bone after advancement of the proximal femoral canal reamer. A method for antegrade removal of a lodged intramedullary guidewire through the distal femoral condyles is described. A set of key technical points to avoid this complication are also provided. Although guidewire migration during hip fracture surgery is a rare occurrence, it is important to recognize the technical measures that can be used to prevent this potentially devastating complication. Surgeons should be familiar with several different techniques for extraction of such hardware surrounding the hip, as there is no universally successful method.
髓内钉是目前治疗股骨转子间骨折最常用的固定器械。最初使用带螺纹的导丝来确定进针点并确定固定器械的最终位置。导丝断裂导致的硬件故障会使手术复杂化,并给外科医生带来意外挑战。硬件的易损机械性能以及手术技术失误可能导致导丝意外断裂或移位。作者报告了一例病例,最初带螺纹的起始导丝移入股骨髓腔,随后在股骨近端扩髓器推进后嵌入股骨远端软骨下骨。本文描述了一种通过股骨远端髁顺行取出嵌顿髓内导丝的方法。还提供了一组避免这种并发症的关键技术要点。虽然髋部骨折手术期间导丝移位很少见,但认识到可用于预防这种潜在灾难性并发症的技术措施很重要。由于没有通用的成功方法,外科医生应该熟悉几种不同的用于取出髋部周围此类硬件的技术。
