'''''Talus'''''
'''''Talus'''''
:The largest bone of the tarsus. It is the medial bone of the proximal row. It can be divided into three distinct areas; the compact '''body''', the '''trochlea''' and the '''head'''. The '''trochlea''' has prominent sagittal ridges dorsoproximally that articulate with the sagittal grooves and intermediate ridge of the distal end of the '''tibia'''. The cylindrical '''head''' is a smaller distal trochlea that articulates with the '''central tarsal bone'''. The plantar and lateral sides articulate with the '''calcaneous'''.

'''''Calcaneus'''''
'''''Calcaneus'''''
:It lies laterally and plantar to the '''talus'''. It articulates medially and dorsally to the talus and distally towards the 4th tarsal bone. It has a proximal plantar projection called the '''calcaneal tuberosity''', it is this that forms the palpable '''point of the hock'''. It acts as a lever for muscles involved in hock extension. The '''susentaculum tali''' lies on the medial aspect of the distal portion of the calcaneus. It supports the deep digital flexor tendon and overlaps the talus on its plantar side.
