     探讨螺旋CT三维重建技术在三踝骨折中的临床应用意义。[方法]回顾性分析1999～2004年56例三踝骨折病例，手术前均行X线正侧位摄片，螺旋CT的扫描参数为厚层2～5 mm，床速3～5 mm，重建间距15～3 mm，而后行螺旋CT三维重建技术并与手术对照。[结果]所有病例螺旋CT三维重建技术明确的显示了骨折的具体情况，螺旋CT三维重建在骨折的分型和碎骨块的描述上较平片优越，与手术中所见相一致。[结论]螺旋CT三维重建能够更为精确的显示三踝骨折的具体情况，对术前治疗方法的选择具有重要的指导意义。

    Abstract：[Objective]To investigate the clinical use of spiral CT with 3D Reconstruction for fractures of the triankle joint. [Method]Fiftysix cases of triankle joint fractures treated in our hospital from 1999 to 2004 were studied respectively. The ankle joint Xray and spiral CT with 3D reconstruction were taken for all the cases preoperatively. The results were analyzed and compared with finding in operation .Scanning parameters of spiral CT were: 2 to 5mm collimation, 3 to 5mm table speed and 1.5 to 3mm reconstruction interval. [Result]Fractures were demonstrated definitely by spiral CT in all the cases. Analyses of the results showed the superiority of spiral CT with 3D reconstruction in the fracture classification. Exact assessment of fragments and total agreement of the preoperative results were compared with findings in operation. [Conclusion]Operative treatment and rehabilitation may provide satisfactory fracture reduction and clinical results for ankle joint fracture. Welltimed treatment, correct fracture pattern estimation, proper internal fixation and rehabilitation are important to achieve better long term results. ......
