If there is a bony projection from the calcaneus, it should be shaved off with the chisel.
A strong band of the plantar aponeurosis connects the projecting part of the tuberosity with the lateral process of the tuberosity of the calcaneus.
It separates the two oblique grooves of the lateral surface of the calcaneus.
It is made up by the calcaneus, the talus, the navicular, the three cuneiforms, and the first, second, and third metatarsals.
Connected to the talus at the subtalar joint, the calcaneus, the largest bone of the foot, is cushioned inferiorly by a layer of fat.
It is commonly injured in sprain-type inversion injuries producing an avulsion fracture at the anterolateral process of the calcaneus.
There are three articulating facets between the talus and the calcaneus, delineated as the anterior, middle and posterior facets.
Within the tarsus, it articulates with the calcaneus below and navicular in front within the talocalcaneonavicular joint.
