A 74-year-old male involved in a pedestrian-automobile collision sustained a comminuted supracondylar-diaphyseal femur fracture. The fracture was stabilized by retrograde intramedullary fixation with a Synthes unreamed tibial nail. Knee motion reached 0 degree-120 degrees by the sixth postoperative day and the fracture healed within twelve weeks. Twelve months after his injury, his knee motion was symmetric to his uninjured side and he had resumed full preinjury activities, including martial arts training. Although antegrade intramedullary nailing remains the treatment of choice for fractures of the femur, this case highlights the usefulness of retrograde nailing and demonstrates the adjunctive application of an existing implant, the tibial nail, in certain special trauma situations.
一名74岁男性在行人与汽车碰撞事故中，发生了股骨髁上-骨干粉碎性骨折。采用Synthes非扩髓胫骨钉逆行髓内固定术对骨折进行了固定。术后第六天膝关节活动度达到0度至120度，骨折在12周内愈合。受伤12个月后，他的膝关节活动度与未受伤侧对称，并且已恢复了伤前的全部活动，包括武术训练。尽管顺行髓内钉固定仍是股骨骨折的首选治疗方法，但该病例突出了逆行髓内钉固定的有效性，并展示了在某些特殊创伤情况下现有植入物（胫骨钉）的辅助应用。
