Calcaneal tuberosity

Calcaneal Tuberosity

The calcaneal tuberosity is a prominent bony structure located at the posterior end of the calcaneus or heel bone. It is a significant anatomical feature in the human skeletal system, playing a crucial role in weight-bearing and locomotion.

Anatomy[edit | edit source]

The calcaneal tuberosity is the largest of the tuberosities found in the human body. It is divided into medial and lateral parts by a vertical septum. The medial part, also known as the medial process, is larger and more prominent. The lateral part, or lateral process, is smaller and less distinct.

The calcaneal tuberosity provides attachment for the Achilles tendon, which is the strongest and largest tendon in the human body. This tendon connects the calf muscles to the heel, enabling walking, running, and jumping.

Clinical Significance[edit | edit source]

Due to its role in weight-bearing and locomotion, the calcaneal tuberosity is susceptible to various injuries and conditions. These include calcaneal spur, a bony outgrowth that can cause heel pain, and calcaneal apophysitis, an inflammation of the growth plate in children and adolescents.

In addition, fractures of the calcaneal tuberosity can occur, often as a result of high-energy trauma such as a fall from height. These fractures are typically associated with significant morbidity and require surgical intervention.
