摘要
目的:探讨CT平扫及三维重建对齿状突合并周围骨折的诊断价值。方法:回顾性分析在我院手术治疗的20例新鲜齿状突骨折合并周围骨折患者的X线片及CT平扫和三维重建资料。结果:20例患者术前影像学诊断齿状突合并周围骨折23处,术中另发现5例患者各有1处术前影像资料漏诊的周围骨折,合并存在的周围骨折共28处。其中单凭X线片确诊齿状突骨折5例,检出率25.0%(5/20),合并周围骨折2处,检出率7.1%(2/28);CT平扫及三维重建确诊齿状突骨折20例,检出率100%(20/20),发现23处周围骨折,检出率82.1%(23/28)。结论:CT平扫及三维重建对齿状突合并周围骨折能作出较全面而准确的诊断,与X线片相比明显提高了骨折的检出率。建议对怀疑有齿状突合并周围骨折的患者进行CT平扫及三维重建检查。
Objective：To discuss CT scan and three-dimensional reconstruction in diagnosing fractures of odontoid process combined with perpheral structure injuries.Method：X-ray and CT three-dimensional（3D） reconstruction image films of 20 cases who had sustained fresh fractures of dens combined with perpheral structure injuries were retrospectively studied.Result：20 patients who had dens fracture also exhibited other 28 sites of injury near the dens.23 sites of surrounding fractures combined with odontoid process fractures were diagnosed by varible image films.Beside these,perpheral fracture unavailable preoperatively was evidenced intraoperatively in 5 cases,with the total perpheral fracture of 28 cases.5 case of dens fracture were determined by X-ray alone with the finding rate of 25.0%（5/20）,among these,2 cases were combined with perpheral structure,with the finding rate of 7.1%（2/28）. 20 cases of dens fracture were determined by CT and 3D reconstruction with the finding rate of 100%.With a total of 23 cases with perpheral fracture identified,the finding rate was 82.1%.Conclusion：CT scan and 3D reconstruction can diagnose fractures of the dens combined with perpheral structure injuries completely and accurately,compared with X-ray,it obviously improves the rate of fracture detection.So CT scan and 3D reconstruction is usually recommended when diagnosing fractures of the dens.
