Inadvertent advancement of guide wire across the knee caused by incarcerated bone fragment at the nail tip during femoral nailing / 中华创伤杂志(英文版)

Fracture of femoral shaft in adults is common and mostly managed with intramedullary interlocking nails. Complications during closed intramedullary femoral nailing are uncommon, and mostly of them are caused by technical reasons. We describe a case of closed nailing for a femoral shaft fracture in which a jammed intramedullary guide wire, due to an incarcerated bone fragment at the nail tip, was inadvertently advanced across the knee. Forceful attempt of nail insertion caused this complication, which was probably attributed to nail design.
