Where is the posterior calcaneus?

The calcaneus, also known as the heel bone, is found at the back of the foot near the ankle, just below the talus, tibia, and fibula bones of the lower leg. The calcaneus is the largest bone in the foot.

What is the tuberosity of calcaneus?

The half of the bone closest to the heel is the calcaneal tuberosity. On its lower edge on either side are its lateral and medial processes (serving as the origins of the abductor hallucis and abductor digiti minimi). On the lateral side is commonly a tubercle called the calcaneal tubercle (or trochlear process).

What is the lateral calcaneus?

The calcaneus lateral view is part of the two view calcaneus series; this projection is used to assess the calcaneus, talocrural, talonavicular and talocalcaneal joint. …

What bones does the calcaneus articulate with?

The calcaneus is located in the hindfoot with the talus and is the largest bone of the foot. It is commonly referred to as the heel. It articulates with the talus superiorly and the cuboid anteriorly and shares a joint space with the talonavicular joint, appropriately called the talocalcaneonavicular joint.

Which is the posterior part of the calcaneus?

The posterior (back) portion is the heel. The Achilles tendon insertion point is on the superior aspect (top) of the posterior part of the calcaneus. There are two bursae (fluid-filled sacs that act as cushions) in front (internal) and behind (external) the insertion point for the Achilles tendon.

When does the apophysis of the posterior calcaneus solidify?

In childhood, there is an apophysis (growth plate) present near the bulbous surface of the posterior calcaneus. This apophysis solidifies, or fuses, around 15 years of age. 2  In some females, it doesn’t solidify until 18 years old. In some males, it doesn’t finish ossifying (hardening into solid bone) until 22 years of age.

How does a calcaneus stress fracture affect the foot?

A physician who examines a runner with a calcaneus stress fracture can usually reproduce pain along the heel. Unlike the pain with plantar fasciitis, which is typically on the sole of the foot at the heel, the pain with a calcaneus stress fracture is more spread out all along the heel.

Where does the calcaneus transfer body weight to?

The calcaneus transfers most of the body weight from the lower limb to the ground. The calcaneus is an irregular, roughly box-shaped bone sitting below the talus. Its long axis is oriented along the mid-line of the foot, however deviates lateral to the mid-line anteriorly.
