目的:通过解剖学研究了解弹簧韧带的解剖特点并探讨其功能作用,同时应用MR观察弹簧韧带,分析其在MRI上的显示情况。方法解剖并观察弹簧韧带,了解其起止、走形及形态特征等情况,测量相关数据。同时对弹簧韧带不同扫描平面的MRI进行分析研究。结果弹簧韧带起于跟骨的载距突,由上内跟舟韧带,内下斜行跟舟韧带和下跟舟韧带3部分组成,分别止于舟骨的上内侧面,舟骨粗隆下和舟骨喙突。MR可以清楚的显示弹簧韧带的各部分结构,在T1及T2加权图像上呈中低信号表现,以矢状面和横断面显示较佳。结论弹簧韧带是足底部承载距骨头的一重要韧带复合体结构,对足纵弓的维持具有重要意义,MR可作为弹簧韧带损伤时的诊断工具。“,”Objective To observe the anatomical characteristics and explore the function of the spring ligament by anatomical study, and to observe morphology of the spring ligament in MRI images. Methods The spring ligament was dissected;its origin, distribution and morphological characteristics were recorded. Meanwhile, analysis of the spring ligament in different scanning planes of the MRI images were carried out. Results The spring ligament is made up of the superomedial calcaneonavicular ligament, the medioplantar oblique calcaneonavicular ligament and the inferoplantar longitudinal calcaneonavicular ligament, which originated from the sustentaculum tali of the calcaneus, and attached to the superomedial aspect of the navicular bone,the bottom of the navicular tuberosity and the navicular beak, respectively. The spring ligament could be displayed clearly on MRI, which was a low signal on T1 and T2 weighted images, and it is better displayed on the sagittal and transverse planes. Conclusion Spring ligament is an important complex of ligamentaneous structures in bearing the head of talus, which has a great significance in maintaining the longitudinal arch of the foot. MR can be used as a diagnostic tool when the spring ligament is injured.
