APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Calcaneus bone: The largest tarsal bone that projects posteriorly as the heel. The calcaneal tuberosity on the plantar surface can be felt under the skin. 2. Talus bone : The talus bone rests on the upper surface of the calcaneus.

Detailed explanation-2: -In humans, the calcaneus is the largest of the tarsal bones and the largest bone of the foot. Its long axis is pointed forwards and laterally. The talus bone, calcaneus, and navicular bone are considered the proximal row of tarsal bones.

Detailed explanation-3: -Seven bones-called tarsals-compose the hindfoot and midfoot. Of these bones, the calcaneus, talus, and navicular are most commonly involved in tarsal coalition.

Detailed explanation-4: -The calcaneus is an irregular bone, cuboid in shape whose superior surface can be divided into three areas-the posterior, middle and anterior aspects. The posterior aspect is rough and concavo-convex in shape.
