What is calcaneus in human body?
It is the largest of the seven articulating bones that make up the tarsus. The calcaneus is located in the hindfoot with the talus and articulates with the talus and cuboid bones. Numerous ligaments and muscles attach to the calcaneus and help with its role in human bipedal biomechanics.[1]
Where is the calcaneus?
The calcaneus is the bone that forms the heel of the foot. It is one of the tarsals, the bones that make up part of the foot and ankle. The calcaneus is the largest bone of the foot and provides the foundation for all of the other tarsals and metatarsals.
Why is calcaneus a large strong bone?
First, the calcaneus absorbs a great deal of impact shock when walking and running. If it were a smaller or thinner bone, it would likely break during high-impact movement. Second, the calcaneus is a strong bone to provide adequate attachment for the Achilles tendon, the strongest tendon found in the body.

How long does a broken calcaneus take to heal?
General Treatment The broken bone will take 3-4 months to heal with or without surgery. If surgery is not needed, there will still be a time where movement and weight bearing is limited. Calcaneus fractures that benefit from surgery often involve breaks within the subtalar joint (the joint just below your ankle joint).
How is a calcaneus fracture treated?
Usually, treatment involves wearing a cast or splint and avoiding putting weight on your heel for up to eight weeks. Most people heal from a calcaneal stress fracture in about three months.
What causes pain under the heel?
Plantar fasciitis is the most common cause of heel pain, accounting for around four out of five cases. Plantar fasciitis is where the thick band of tissue that connects the heel bone with the rest of the foot (the plantar fascia) becomes damaged and thickened.

The tibia articulates with the talus ...
Why do calcaneus fractures cause bone to widen?
Because most calcaneus fractures cause the bone to widen and shorten, the goal of treatment is to restore the normal anatomy of the heel. In general, patients whose normal heel anatomy is restored have better outcomes. In most cases, recreating the normal heel anatomy involves surgery.

What is the Calcaneus Bone
Calcaneus or heel bone is an irregularly-shaped, short, cuboidal bone located in the hindfoot, just below the ankle. It is the largest tarsal, as well as the largest foot bone that forms the prominence of the heel. It is a weight-bearing bone, supporting the entire body weight while standing or walking.
Where is the Calcaneus Located
Calcaneus is located in the hind region of the foot, specifically in the heel region. More specifically, it lies below the three bones, the talus, tibia, and fibula that make up the ankle joint. Whenever you touch your heel, you can feel the calcaneus.
Anatomy – Parts and Bony Landmarks of the Calcaneus
As stated, the calcaneus is an irregular cuboid bone whose superior surface can be divided into three areas – the posterior, middle, and anterior regions.
Joints and Articulations
1. Talocalcaneal or Subtalar Joint: A synovial joint, formed betweencalcaneus and talus.
Muscle and Ligament Attachments
As the calcaneus is the largest foot bone, it provides a large surface area for the complex attachment of these following muscles:
Identification of Left and Right Calcaneus
First, hold or place the bone in a way so that the convex superior surface is up. In this position, the smooth anterior surface would be on the outer side, and the posterior surface, i.e., the side of the heel, would be on your side.
