摘要
目的观察跗跖关节韧带的走行和分布。方法解剖观察跗跖关节的韧带,测量相关数据。结果跗跖关节背侧的韧带扁而薄,相邻骨骼间呈纵行,横行或斜行分布。除第1、2跖骨间无骨间韧带外,相邻跖骨间、楔骨间、外侧楔骨与骰骨间和内侧楔骨与第2跖骨基底部之间均有韧带相连。在跗跖关节的跖侧,胫骨后肌腱向远端延伸的纤维连接3块楔骨和第1~4跖骨基底部,形成一个韧带群;内侧楔骨与第1、2跖骨基底部各有韧带相连;外侧楔骨和骰骨与第3~5跖骨基底部有一横行韧带相连。结论跗跖关节的韧带数量众多,分布广泛,是维持跗跖关节稳定的主要结构。
Objective To explore anatomic features of the tarsometatarsal ligaments.Methods The tarsometatarsal ligaments were dissected,observed and measured on cadaveric specimens.Results Dorsal tarsometatarsal ligaments were flat and thin.They were longitudinal,transverse or oblique between adjacent bones.There were interosseous ligaments among the metatarsal bones（2~5 metatarsal bone）,the cuneiform bones,the lateral cuneiform bone and the cuboid bone,the medial cuneiform bone and the second metatarsal base.At the plantar side of the tarsometatarsal joint,the fibers of posterior tibial tendon extended to the distal part of the foot connected three cuneiform bones and the bases of 1~4 metatarsal bones,which formed a group of ligaments.There was a ligament among the medial cuneiform bone and the base of 1 and 2 metatarsal bone respectively.As well,a transverse ligament connected the lateral cuneiform bone,the cuboid bone and the base of 3~5 metatarsal bone.Conclusions The tarsometatarsal ligaments are the main structures to maintain the stability of tarsometatarsal joints.
