神经源性骨化性肌炎是一种影响大关节的致残状态，患者患有严重的创伤后中枢神经系统损害。它可能导致关节僵硬和血管或神经压迫。手术可能有潜在的出血、神经血管损伤、医源性骨折和骨软骨损伤的危险。我们对45个患有神经性骨化性肌炎并需要手术的强直髋关节进行了术前容积CT评估。螺旋CT静脉对比剂结合二维和三维表面重建是唯一的术前成像方法。这使异位骨与邻近血管有了很好的区分。我们证实，损伤后24个月内的早期手术既不合并围手术期骨折，也不合并神经源性骨化性肌炎的早期复发。手术延迟与关节空间的丧失和更大程度的骨脱矿有关。增强的容积CT是一种很好的术前评估神经源性骨化性肌炎的方法，并且与手术结果有很好的相关性。
Neurogenic myositis ossificans is a disabling condition affecting the large joints of patients with severe post-traumatic impairment of the central nervous system. It can result in ankylosis of the joint and vascular or neural compression. Surgery may be hazardous with potential haemorrhage, neurovascular injury, iatrogenic fracture and osteochondral injury. We undertook pre-operative volumetric CT assessment of 45 ankylosed hips with neurogenic myositis ossificans which required surgery. Helical CT with intravenous contrast, combined with two- and three-dimensional surface reconstructions, was the only pre-operative imaging procedure. This gave good differentiation of the heterotopic bone from the adjacent vessels. We established that early surgery, within 24 months of injury, was neither complicated by peri-operative fracture nor by the early recurrence of neurogenic myositis ossificans. Surgical delay was associated with a loss of joint space and a greater degree of bone demineralisation. Enhanced volumetric CT is an excellent method for the pre-operative assessment of neurogenic myositis ossificans and correlates well with the operative findings.
