Medial ligament (Deltoid ligament)
The medial (deltoid) ligament is large, strong (Fig. 6.83), and triangular in shape. Its apex is attached above to the medial malleolus and its broad base is attached below to a line that extends from the tuberosity of the navicular bone in front to the medial tubercle of the talus behind. The medial ligament is subdivided into four parts based on the inferior points of attachment (Fig. 6.83):
1.The part that attaches in front to the tuberosity of the navicular and the associated margin of the plantar calcaneonavicular ligament (spring ligament), which connects the navicular bone to the sustentaculum tali of the calcaneus bone behind, is the tibionavicular part of the medial ligament. (胫舟韧带:起内踝前缘-舟骨粗隆及跟舟跖韧带内侧缘:防距骨内移)
2.The tibiocalcaneal part, which is more central, attaches to the sustentaculum tali(载距突 of the calcaneus bone. (胫跟韧带:内踝尖-跟骨载距突,防踝关节内翻)
3.The posterior tibiotalar part attaches to the medial side and medial tubercle of the talus. (胫距后韧带:胫骨前后丘间沟及胫骨远端后丘-距骨内侧面及距骨后突内侧结节)
4.The fourth part (the anterior tibiotalar part) is deep to the tibionavicular and tibiocalcaneal parts of the medial ligament and attaches to the medial surface of the talus.(胫距前韧带:内踝前缘-距骨颈,维持胫骨与距骨在内侧方的稳定)

Lateral ligament
The lateral ligament of the ankle is composed of three separate ligaments, the anterior talobular ligament, the posterior talobular ligament, and the calcaneobular ligament (Fig. 6.84):
1.The anterior talobular ligament is a short ligament, and attaches the anterior margin of the lateral malleolus to the adjacent region of the talus. (距腓前韧带:外踝前缘-距骨颈外侧面,相对软弱,内翻易损伤)
2.The posterior talobular ligament runs horizontally backward and medially from the malleolar fossa on the medial side of the lateral malleolus to the posterior process of the talus. (距腓后韧带:外踝内侧面的指状窝-距骨后突外侧结节;是外侧韧带群中最强韧的部分
3.The calcaneobular ligament is attached above to the malleolar fossa on the posteromedial side of the lateral malleolus and passes posteroinferiorly to attach below to a tubercle on the lateral surface of the calcaneus.(跟腓韧带:外踝尖前方的压迹-跟骨外侧面中部结节)

下胫腓关节:主要是胫腓韧带复合体,包括:骨间韧带,下胫腓前韧带,下胫腓后韧带,胫腓横韧带
1.骨间韧带:骨间膜向下延伸部,从上内向下外斜行,连接胫腓骨远端相向面,可加强腓骨稳定性;
2.下胫腓前韧带:坚强的三角形韧带,起自胫骨下端前外角(Chaput结节),止于外踝前缘;
3.下胫腓后韧带:自胫骨远端后外角(Volkman结节)止于腓骨后缘,防腓骨内旋;此韧带较前韧带坚韧且富有弹性,因此前方的损伤常是下胫腓前韧带撕裂,而后方的损伤通常是胫骨远端后结节撕脱骨折;
4.胫腓横韧带:位于下胫腓后韧带下方,增加了踝穴后方的深度;
