A calcaneal spur (also known as a heel spur) is a bony outgrowth from the calcaneal tuberosity (heel bone). [1] Calcaneal spurs are typically detected by x-ray examination. [2] It is a form of exostosis. When a foot is exposed to constant stress, calcium deposits build up on the bottom of the heel bone. Generally, this has no effect on a person ...
In humans, the calcaneus is the largest of the tarsal bones and the largest bone of the foot. Its long axis is pointed forwards and laterally. [2] The talus bone, calcaneus, and navicular bone are considered the proximal row of tarsal bones. [3] In the calcaneus, several important structures can be distinguished: [3]
High arches can also cause plantar fasciitis as they cause the plantar fascia to be stretched away from the calcaneus or heel bone. Additionally, high or low arches can increase the risk of shin splints as the anterior tibialis must work harder to keep the foot from slapping the ground. [8]
The medial calcaneal branches of the tibial nerve (internal calcaneal branches) perforate the laciniate ligament, and supply the skin of the heel and medial side of the sole of the foot. [ 1 ] Structure
The hindfoot is composed of the talus (or ankle bone) and the calcaneus (or heel bone). The two long bones of the lower leg, the tibia and fibula, are connected to the top of the talus to form the ankle. Connected to the talus at the subtalar joint, the calcaneus, the largest bone of the foot, is cushioned underneath by a layer of fat. [2]
The Achilles tendon is also known as the "tendo calcaneus" (Latin for "calcaneal tendon"). [9] Because eponyms (names relating to people) have no relationship to the subject matter, most anatomical eponyms also have scientifically descriptive terms. The term calcaneal comes from the Latin calcaneum, meaning heel.
A calcaneal fracture is a break of the calcaneus (heel bone). [1] Symptoms may include pain, bruising, trouble walking, and deformity of the heel . [ 1 ] It may be associated with breaks of the hip or back .
Achilles anatomy. The Achilles tendon is the strongest and thickest tendon in the body. [12] It connects the calf muscles to the heel bone of the foot. The calf muscles are the gastrocnemius, soleus and the heel bone is called the calcaneus. It is approximately 15 centimeters (5.9 inches) long and begins near the middle part of the calf.
