The calcaneus is the large bone that forms the heel of the foot and supports the body’s weight during standing and walking. In musculoskeletal ultrasound, the calcaneus is most commonly examined in relation to its attachment to the Achilles tendon and the plantar fascia. Ultrasound can identify fractures, stress reactions, and erosions of the calcaneus, as well as inflammation at the insertions of tendons and ligaments. Heel pain is one of the most common complaints evaluated with foot ultrasound, and the calcaneus serves as an important anatomical landmark for locating and assessing these soft tissue structures.
