摘　　要：目的探讨单排螺旋CT扫描技术在足踝小关节外伤中的应用价值.方法收集2011年1月至2012年2月足踝部外伤患者97例,男57例,女40例.全部行X线摄片、CT轴位及准冠状位扫描.结果 97例中检出132处骨折,10处脱位;X线片显示骨折111处,脱位8处;常规轴位CT扫描显示骨折122处,脱位7处;准冠状位CT扫描显示骨折131处,脱位10处.结论单层螺旋CT选择合理的扫描方案,尤其准冠状位检查对显示涉及关节面的骨折以及合并踝跗骨多发骨折有明显优势,对提高隐匿骨折检出率具有重要的价值.Objective To discuss the value of single spiral CT scanning techniques in diagnosis of small joints injury in ankle.Methods We collected the data of 97 patients with ankle injury,including 57 male and 40 female patients from January 2011 to February 2012.All patients were given X-ray radiography,CT axial scanning and coronal scanning.Results We detected in 132 fractures and 10 dislocations in 97 patients.111 fractures and 8 dislocations were showed by X-ray radiography.122 fractures and 7 dislocations were showed by Conventional axial CT scan.131 fractures and 10 dislocations were showe by Standard coronary CT scan.Conclusion For single spiral CT scan,the choice of reasonable scheme,especially standard coronary CT scan has advantages in displaying the multiple fractures with articular surfaces and ankle tarsal bones,and has an important value in improving the detection rate of the hidden fractures.
