【摘要】：目的:总结踝关节骨折CT表现及特点,分析CT图像与常用踝关节骨折分型之间的关系。方法:回顾性调查369例成人踝关节骨折,分析踝穴上1 cm水平横断面CT图像及其特点,进行踝关节骨折X线分型,分析CT图像与骨折X线分型之间的关系。结果:踝穴上1 cm水平横断面CT图像共有8种表现形式,以a、b、c分别指代腓骨骨折、后踝骨折和骨间韧带(interosseous tibiofibular ligament,IOL)断裂,369例踝关节骨折CT图像包括:0度(腓骨、后踝、IOL均完整)40例;Ⅰa度(腓骨骨折、后踝完整、IOL完整)60例,Ⅰb度(腓骨完整、后踝骨折、IOL完整)3例,Ⅰc度(腓骨完整、后踝完整、IOL断裂)26例;Ⅱab度(腓骨骨折、后踝骨折、IOL断裂)163例,Ⅱac度(腓骨骨折、后踝完整、IOL断裂)6例,Ⅱbc度(腓骨完整、后踝骨折、IOL断裂)61例;Ⅲ度(腓骨骨折、后踝骨折、IOL断裂)10例。根据Danis-Weber骨折分型:A型骨折18例,B型骨折238例,C型骨折94例,腓骨无骨折19例。分析CT图像,A、B、C型骨折IOL断裂的发生率分别为0、5.9%、88.3%;CT图像与Danis-Weber分型之间存在相关性,IOL断裂的发生率随Danis-Weber分型严重程度而改变,经秩相关检验,差异有统计学意义(Spearman R=0.781,P0.001)。CT图像能发现X线骨折分型无法判断的IOL断裂,其发生率是5.9%。结论:踝穴上1 cm水平横断面CT图像在术前能够清楚判断下胫腓联合IOL损伤情况,与Danis-Weber骨折分型存在良好的相关性,并能发现某些X线片中无法判断的IOL断裂情况。
[Abstract]:Objective: to summarize the CT findings and characteristics of ankle fractures and analyze the relationship between CT images and classification of ankle fractures. Methods: 369 cases of adult ankle fractures were investigated retrospectively. the CT images and their characteristics of 1 cm horizontal section on ankle acupoints were analyzed. The X-ray classification of ankle fractures was carried out, and the relationship between CT images and X-ray classification of fractures was analyzed. Results: there were 8 manifestations of 1 cm horizontal cross section CT images on ankle acupoints. A, b, c referred to fibular fracture, posterior malleolus fracture and (interosseous tibiofibular ligament,IOL fracture of interosseous ligament, respectively. CT images of 369 cases of ankle fracture included: 0 degree (fibula, posterior malleolus, IOL) in 40 cases; There were 60 cases of degree 鈪，
