Figure 6-16. (A) Cranial–caudal projection of the equine tarsus. (B) Lateral projection of the equine
tarsus. C, calcaneus; T, talus; ct, central tarsal bone; 2, second tarsal bone; 3, third tarsal bone; 4, fourth
tarsal bone; MT III, third metatarsal bone; MT II, second metatarsal bone (medial splint bone); MT IV,
fourth metatarsal bone (lateral splint bone). The second and fourth tarsal bones are largely superimposed
in the lateral view and are therefore not labeled. Source: radiographs courtesy of Susan Kraft, DVM.
Amongst the tarsal bones, the large the other tarsal bones by many short,
calcaneus projects proximad and caudad strong ligaments. The ligaments are less
to form a lever for attachment of the extensive over the craniomedial aspect of
common calcaneal tendon (Achilles ten- the hock. In this location, the joint cap-
don), which is the common insertional sule is immediately beneath the skin, and
tendon of the extensor muscles of the distension of this joint results in an obvious
hock. The calcaneus is firmly attached to soft bulge commonly called a bog spavin.
