Articulation between the small, numbered tarsal bones and the metatarsals.

Articulation between the small, numbered tarsal bones and the metatarsals.

 

 

 

The medial and lateral (long) collateral ligaments arise from their respective malleoli on the tibia and terminate on the proximal ends of corresponding splints. Between these points they attach on some of the tarsal bones they cross. The long plantar ligament extends from calcaneus distally to metatarsal bones and is attached to vasious tarsal bones. The synovial membrane is fivided into 4 joint cavities. Tarsocrural joint capsule has dorsal and 2 plantar pouches, areas where fibrous capsule is weak and free to bilge when joint cavity distended by synovial fluid accumulatiob.

**Short lateral collateral: Deep to the long lateral collateral. It arises from the lateral maleolus of the tibia and attaches via two branches, one to the calcaneus and one to the talus.

**Long medial collateral: Arises from the medial malleolus and terminates on the proximal end of metatarsal II (medial splint). Between these points it attaches to the medial tarsal bones.

**Short lateral collateral: Deep to the long medial collateral. It arises from the medial malleolus and attaches via two branches, one on the calcaneus and one on the talus.

*Long plantar ligament: Extends on the plantar aspect of the hock from the calcaneal tuberosity distally to the proximal end of the third and fourth metatarsal bones and also attaches to the central and fourth tarsal bones.
