Tubercle of the Calcaneus

The calcaneal tuberosity (also known as tuber calcanei, pna, bna, jna or calcaneal tubercle) is an anatomical structure located on the back of the calcaneus. This tubercle is an important element of the skeleton of the lower limb and plays a key role in maintaining balance and movement in humans.

A calcaneal bump forms as a result of stress and stress placed on the heel bone during movement and standing. It projects forward from the base of the heel bone and serves as an anchoring point for the ligaments, tendons, and muscles that control foot movement and shock absorption during walking and running.

One of the main functions of the calcaneal tuberosity is to support the arch of the foot. The arch of the foot is made up of many bones, tendons and ligaments, and its proper function is critical to maintaining stability and shock absorption during movement. The calcaneal tuberosity serves as a support point for tendons and muscles that support the arch of the foot and prevent flat feet or other deformities.

In addition, the calcaneal tuberosity plays an important role in locomotion. It serves as an anchor point for the Achilles tendon, the largest tendon in the body, which connects the calf muscles to the heel bone. The Achilles tendon is responsible for flexion of the foot and maintains plantar flexion, allowing us to walk, run and perform other motor activities.

It should also be noted that the tubercle of the calcaneus can become the object of inflammation and various pathological conditions. For example, a heel spur, or calcification, is an osteophyte, or new bone formation, that can occur in the area of ​​the tubercle of the heel bone. This condition is usually associated with repetitive microtrauma associated with improper footwear, overuse, or prolonged periods of standing.

In conclusion, the calcaneal tuberosity is an important anatomical element that supports the stability and movement of the foot. It serves as an attachment point for the tendons and muscles that control movement of the lower limb and plays a key role in maintaining balance and ambulation. Understanding the function and potential problems associated with the calcaneal tuberosity is important to the health and well-being of our mobility system.
