Where is calcaneus located?

Where is calcaneus located?

The calcaneus is a roughly rectangular prism-shaped bone located inferior to the talus and posterior to the midfoot. The long axis of the prism extends approximately along the mid-line of the foot. To understand the calcaneus structure, it is necessary to examine its six surfaces separately.

What attaches to the posterior calcaneus?

The posterior part of the calcaneus is circular, with three facets (superior, middle and inferior). The superior facet is separated from the calcaneal tendon by the retrocalcaneal bursa. The middle facet provides the attachment site for the calcaneal tendon (Achilles tendon).

Is calcaneal anterior or posterior?

The calcaneus is an irregular, roughly box-shaped bone sitting below the talus. Its long axis is orientated along the mid-line of the foot, however deviates lateral to the mid-line anteriorly. It projects posteriorly to form the core of the heel.

Is the calcaneal region is on the posterior side of the body?

The calcaneal region is on the posterior side of the body. The bones of the leg are described as deep, while the ears are attached superficially. The vertebral region is medial to the scapular region. The carpal region is distal to the digital region.

What is the calcaneus called in layman’s terms?

Heel bone: Formally called the calcaneus. The calcaneus (from the Latin calcaneum, meaning heel or heel bone) is a bone of the tarsus of the foot which constitutes the heel. In humans, the calcaneus is the largest of the tarsal bones and the largest bone of the foot.

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 noticeable bump on the outside of the ankle?

The most common fracture is to the bony bump on the outside of the ankle, the lateral malleolus. The lateral malleolus is the bottom of the fibula, the smaller lower leg bone. The bump on the inside of your ankle, the medial malleolus, is less commonly fractured.

Where is the medial calcaneal tubercle?

The medial tuberosity is the main aspect of the calcaneus through which weight bearing takes place. The medial and lateral tuberosities are the points at which the intrinsic muscles in the first layer of the foot originate. It is also the point at which the plantar fascia attaches.

What attaches to the medial calcaneus?

Three muscles insert on the calcaneus: the gastrocnemius, soleus, and plantaris. These muscles are part of the posterior compartment of the leg and aid in walking, running and jumping.

What is the process of calcaneus called?

On the lateral side is commonly a tubercle called the calcaneal tubercle (or trochlear process). This is a raised projection located between the tendons of the peroneus longus and brevis. It separates the two oblique grooves of the lateral surface of the calcaneus (for the tendons of the peroneal muscles).

What does it mean when the back of your heels hurt?

Heel pain, especially stabbing heel pain, is most often caused by plantar fasciitis, a condition that is sometimes also called heel spur syndrome when a spur is present. Heel pain may also be due to other causes, such as a stress fracture, tendonitis, arthritis, nerve irritation or, rarely, a cyst.

What is the posterior portion 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.

What is the posterior calcaneal spur?

Posterior Calcaneal Spur – Diseases of the Achilles Tendon – CENTRE FOR ORTHOPAEDICS, SPORTS MEDICINE AND REHABILITATION – Dr. Erich H. Rembeck – Munich, Germany A special form of chronic achilles tendon pain is the posterior calcaneal spur, often referred to as Haglund exostosis.

What is the insertion point of the calcaneal tendon?

The middle surface of the posterior portion of the calcaneus is the insertion point of the calcaneal tendon. The most superior portion of the calcaneus connects to a tarsal bone, called the talus, above it.

What causes a fraying of the calcaneum?

In this case there is an enlargement of the posterior calcaneum, which results in a fraying of the achilles tendon on the calcaneum. As a consequence, in less serious cases only an inflammation of the protective tendon bursa arrises.
