摘　　要：[目的]通过对下胫腓联合的CT测量,观察下胫腓联合在CT扫描图象上的解剖特性,并探讨临床意义。[方法]对12例正常踝关节进行下胫腓联合轴向扫描,测量指标统计学处理。[结果]胫骨的腓骨切迹前部较后部短,切迹前后部夹角为(137.45±9.59)°,切迹深度(4.36±1.15)mm,胫腓重叠的垂直距离为(7.01±2.02)mm。[结论]胫骨的腓骨切迹深度、切迹内腓骨的位置影响下胫腓联合的稳定性。对下胫腓联合分离,CT轴向扫描用于诊断和治疗后的评估较为可靠。[Objective] To observe the anatomic characteristics of the distal tibiofibular syndesmosis on CT axial scan image and elucidate clinical significance. [ Method] The distal tibiofibular syndesmosises of 12 normal persons （6 male and 6 female） were scanned axially. The parameters were analyzed statistically.[Result] The anterior facet was shorter than the posterior facet of the fibular incisure of the tibia. The angle between anterior and posterior facets of incisure was （ 137.45±9.59 ）° The depth of the incisure was （4.36± 1.15 ） mm. The vertical distance of tibiofibular overlapping was （ 7.01±2.02 ） mm. [ Conclusion ] The stability of the distal tibiofibular syndesmosis was affected by the depth of fibula incisure of the tibia and the position of fibula in incisure. A CT axial scan performed for preoperative or postoperative evaluation of the integrity of the distal tibiofibular syndesmosis is comparatively reliable.
