【摘要】：背景:在第二跖骨和内侧楔状骨之间的3条韧带中,Lisfranc韧带最强壮,其强度是背侧韧带的3倍,所以Lisfranc韧带对于维持第2跖骨和内侧楔骨之间的稳定至关重要,但单纯Lisfranc韧带的损伤对跖跗关节稳定性的研究,国内外均末见报道。方法/设计:解剖学测量及生物力学实验。(1)采用防腐尸体标本,对Lisfranc韧带的起点、止点、走行、长度、宽度及厚度进行解剖学观测及统计。(2)选择新鲜人体足部标本,利用生物力学测试方法,依次切断背侧韧带、Lisfranc韧带和跖侧韧带分别加载,采用引伸计测量不同负载下第一、二跖骨基底之间的位移变化,探讨Lisfranc韧带对跖跗关节稳定性的影响。讨论:实验利用生物力学测试方法,探讨Lisfranc韧带对跖跗关节稳定性起何作用,同时通过对Lisfranc韧带的解剖学观测,提高临床上对Lisfranc韧带重要性的认识,为临床跖附关节损伤的治疗提供理论依据。伦理批准:研究经广州市正骨医院医学伦理委员会批准。
[Abstract]:Background: of the three ligaments between the second metatarsal bone and the medial cuneiform bone, the Lisfranc ligament is the strongest and is three times stronger than the dorsal ligament. Therefore, the Lisfranc ligament is essential for maintaining stability between the second metatarsal bone and the medial cuneate bone. However, the study on the stability of tarsometatarsal joint caused by simple Lisfranc ligament injury is rarely reported at home and abroad. Methods: anatomical measurement and biomechanical experiment. Anatomic observation of width and thickness and statistics. 2) fresh human foot specimens were selected. By biomechanical test, Lisfranc ligament and metatarsal ligament were cut off and loaded respectively. The first was measured by extensometer under different loads. The effect of Lisfranc ligament on the stability of tarsometatarsal joint was discussed by using the biomechanical test method to explore the effect of Lisfranc ligament on the stability of tarsometatarsal joint. At the same time, the anatomical observation of the Lisfranc ligament can improve the clinical understanding of the importance of the Lisfranc ligament, and provide a theoretical basis for the treatment of the injury of the metatarsophalangeal joint. Ethical approval: the study was approved by the Medical Ethics Committee of Guangzhou Zhenggu Hospital.
