A 63-year-old man with a comminuted spiral femoral shaft fracture was treated with closed reduction and internal fixation with a cephalomedullary nail. Two weeks postoperatively, one of the two static distal interlocking bolts began backing out and was removed. The nail ultimately migrated distally and perforated the knee joint at four months postoperatively. The patient was successfully treated with an exchange nail and percutaneous bone graft to the fracture site. A single static distal interlocking bolt may be inadequate to maintain length in a healing comminuted spiral femur shaft. Multiple distal interlocking bolts should be in place until the completion of fracture healing.
一名63岁男性因股骨干粉碎性螺旋骨折接受了闭合复位和带锁髓内钉内固定治疗。术后两周，两个静态远端锁定螺栓中的一个开始松动并被取出。术后四个月，髓内钉最终向远端移位并穿透膝关节。患者通过更换髓内钉和骨折部位经皮植骨成功治愈。单个静态远端锁定螺栓可能不足以维持粉碎性螺旋股骨干愈合过程中的长度。在骨折愈合完成之前，应使用多个远端锁定螺栓。
