摘　　要：目的初步探讨脑组织损伤后出现异位骨化的临床X线特征。方法回顾性分析12例脑组织损伤后出现异位骨化患者的临床X线资料,观察异位骨化的部位、形态、出现骨化的时间及相关因素。结果12例均为痉挛性完全瘫痪患者,骨化出现在髋关节周围4例、肘关节周围4例、膝关节周围3例、肩关节周围1例。骨化形态呈云絮状6例、斑片状5例、条片状1例。从脑组织损伤到出现异位骨化的时间最短50天,最长5年,平均300.7天。结论痉挛及完全瘫痪为脑源性异位骨化发病相关因素,异位骨化多发生于大关节周围,其X线表现以云絮状、斑片状改变多见。Objective：To discuss the clinical and X-ray features of heterotopic ossification （HO） after brain injury. Methods：The clinical and X-ray findings including location and pattern, the time-period of HO formation after brain injury and the other relative factors in 12 patients were observed and analyzed retrospectively. Results.. All of these 12 cases had spastic and/or complete paraplegia. The peri-articular HO usually located at hip （4 cases）,elbow （4 cases）,knee （3 cases） and shoulder joint （1 cases） respectively. The manifestations of HO appeared as cloudy （6 cases）, patchy （5 cases） and thread-like （1 cases）. The time duration from brain injury to the formation of HO ranged from 50 days to 5 years （mean 300. 7 days）. Conclusion：The peri-articular HO after brain injury usually located at large joints. Most of the X-ray features were cloudy and patchy calcifications. Spastic and/or complete paraplegia were the relative factors of HO after brain injury.
