目的探讨MSCT重建技术(三维重建及冠状位/矢状位重建)在腕关节骨折诊断中的应用价值及其对临床治疗的意义。方法回顾性分析本院2011年1月至2012年2月收治的腕关节外伤185例,所有病例先作常规X线检查,再作CT检查,并进一步作CT三维重建及冠状位/矢状位重建。结果所有病例经MSCT常规平扫及重建检查剔除无骨折病例(31例)后,将骨折病例分为三组,第一组桡骨远端骨折伴或不伴尺骨茎突骨折97例,及单纯尺骨茎突骨折2例;第二组腕骨骨折47例,其中单块腕骨骨折44例、多块腕骨骨折3例;第三组桡骨远端骨折伴或不伴尺骨茎突骨折,同时有腕骨骨折8例。结论常规MSCT扫描运用重建技术基本能够明确腕关节外伤病例是否存在骨折,发现隐匿性骨折及细微骨折,判断骨折对关节面的影响,对临床选择治疗方案提供直观信息。
Objective To explore the value of MSCT reconstruction (three-dimensional reconstruction and coronal / sagittal reconstruction) in the diagnosis of wrist fracture and its clinical significance. Methods A retrospective analysis of our hospital from January 2011 to February 2012 admitted to the wrist injury in 185 cases, all cases of conventional X-ray examination before CT examination and further CT three-dimensional reconstruction and coronal / sagittal reconstruction. Results All the cases were divided into three groups after fracture removal and reconstruction without any fracture (31 cases). The first group included 97 cases of distal radius fracture with or without ulnar styloid fracture, and simple ulna Styloid fracture in 2 cases; the second group of 47 cases of carpal fractures, including a single carotid fracture in 44 cases, multiple carpal fractures in 3 cases; the third group of distal radius fractures with or without ulna and styloid process fractures, while carpal fractures 8 example. Conclusion Conventional MSCT scan reconstruction can basically confirm the existence of fractures in patients with wrist trauma and find occult fractures and minor fractures to determine the effect of fractures on the articular surface and provide intuitionistic information for clinical treatment options.
