Heterotopic ossification at the site of insertion of an intramedullary nail was observed in five central nervous system-injured patients with femoral fractures. Three of these patients experienced a reduction in the range of motion of the ipsilateral hip joint, which in two improved with physical therapy. Patients with central nervous system injury who have closed interlocking intramedullary nail fixation may be at increased risk of heterotopic ossification at the surgical site.
在5例患有股骨骨折的中枢神经系统损伤患者中，观察到髓内钉插入部位出现异位骨化。其中3例患者同侧髋关节活动范围减小，其中2例经物理治疗后有所改善。接受闭合式带锁髓内钉固定的中枢神经系统损伤患者，手术部位发生异位骨化的风险可能会增加。
