目的 基于MRI探讨Lisfranc韧带的形态学特点及其与邻近骨的解剖关系，为Lisfranc韧带损伤诊治提供影像学参考。 方法 回顾性分析2010年1月至2021年5月西南医科大学附属中医医院收治的232例患者MRI影像学资料，测量Lisfranc韧带的宽及长、Lisfranc韧带止点至第2跖骨外侧缘距离、Lisfranc韧带起点至内侧楔骨内侧缘距离、Lisfranc韧带分别与第1跖骨、内侧楔骨及第2跖骨中轴的夹角等形态学数据。 结果 Lisfranc韧带宽（5.67±1.47）mm，长（9.61±2.81）mm，Lisfranc韧带止点至第2跖骨外侧缘距离为（11.69±2.63）mm，Lisfranc韧带起点至内侧楔骨内侧缘距离为（18.83±3.39）mm，Lisfranc韧带与第1跖骨中轴夹角为（51.75±11.01）°，与内侧楔骨中轴夹角为（38.93±11.40）°，与第2跖骨中轴夹角为（33.93±10.17）°。 结论 本研究获得Lisfranc韧带详细的MRI解剖学数据及其与邻近骨的解剖关系，可为Lisfranc韧带损伤的MRI影像诊断、临床诊断和手术修复提供一定的参考，避免盲目放置内固定而造成Lisfranc韧带损伤。
Abstract
Objective To explore the morphological characteristics of Lisfranc ligament and its anatomical relationship with adjacent bones based on MRI, so as to provide imaging reference for the diagnosis and treatment of Lisfranc ligament injury. Methods The MRI imaging data of 232 outpatients and inpatients in the Affiliated Traditional Chinese Medicine Hospital of Southwest Medical University were retrospectively analyzed, and the morphological data of Lisfranc ligament was measured, including the width and length, distance from the ending point of Lisfranc ligament to lateral margin of the second metatarsal bone, distance from origin of Lisfranc ligament to the medial margin of cuneiform bone, angles between the ligament and the central axis of the first metatarsal bone, the central axis of medial cuneiform bone, and the central axis of the second metatarsal bone. Results The average width and length of Lisfranc ligament were (5.67±1.47) mm and (9.61±2.81) mm, respectively. The distance from the ending ponit of ligament to the lateral margin of the second metatarsal bone was (11.69±2.63)mm. The distance from the origin of ligament to the medial margin of cuneiform bone was (18.83±3.39) mm. The average angles between ligament and the central axis of the first metatarsal, central axis of the medial cuneiform bone, central axis of the second metatarsal bone were (51.75±11.01 )°, (38.93 ±11.40)°, (33.93 ±10.17) °, respectively. Conclusions In this study, the detailed MRI anatomical data of Lisfranc ligament and its anatomical relationship with adjacent bones were obtained, which can provide certain reference for MRI diagnosis, clinical diagnosis and surgical repair of ligament injury, and avoid Lisfranc ligament injury caused by blind internal fixation.
