摘要
目的探讨多层螺旋CT三维重组对骶骨骨折的临床应用价值。资料与方法对46例骶骨骨折患者的X线、多层螺旋CT三维成像资料进行回顾性对比分析。结果X线平片确诊27例(58.7%,27/46),漏诊19例(41.3%,19/46),CT三维成像明确诊断44例(95.7%,44/46),漏诊2例(4.3%,2/46)。对确诊的骶骨骨折进行Denis分类,X线平片正确分型20例(74.1%,20/27),CT三维成像正确分型44例(100%,44/44),X线平片与CT三维成像组之间的差异有显著的统计学意义(P值均<0.01)。46例骶骨骨折患者,34例行保守治疗,12例手术治疗,手术所见与CT扫描结果完全一致。结论螺旋CT三维成像对骶骨骨折的诊断、分类及指导治疗具有重要的意义和作用。
Objective To investigate clinical value of 3 dimensional reconstruction with spiral CT（3D CT）in sacrum fracture compared with conventional X-ray. Materials and Methods Conventional X-ray and 3-D CT data of 46 sacrum fractures were analyzed retrospectively. Results 27 cases （58.7%,27/46）were definitely diagnosed and 19 cases （41.3%,19/46）were missed by X-ray,while 44 cases （95.7%,44/46）were definitely diagnosed and 2 cases （4.3%,2/46）were missed by 3-D CT. According to Denis classification of fracture,20 cases （74.1%,20/27）were definitely classified by X-ray,while 44 cases （100%,44/44）were definitely classified by 3-D CT. There was significant difference of accurate diagnosis between conventional X-ray group and 3-D CT（P0.01）. 12 patients were operated and the surgical foundings was consistent with 3-D CT results. Conclusion 3-D CT is valuable in definitely diagnosing and exactly classifying the sacral fractures and provides valuable information on guiding therapeutic methods.
