What is the calcaneal?
Table of Contents
The calcaneus (heel bone) is the largest of the tarsal bones in the foot. It lies at the back of the foot (hindfoot) below the three bones that make up the ankle joint. These three bones are the: Tibia — shinbone.
What is the calcaneal attachment?
The posterior surface of the calcaneus has a circular convex structure with three distinct facets. The middle facet serves as the attachment site for the calcaneal tendon (Achilles tendon), while the superior facet is separated from the calcaneal tendon by the retrocalcaneal bursa.
What is calcaneal tuberosity?
cal·ca·ne·al tu·ber·os·i·ty. [TA] the posterior extremity of the calcaneus, or os calcis, forming the projection of the heel.
Where is the calcaneal tuberosity?
The half of the bone closest to the heel is the calcaneal tuberosity. On its lower edge on either side are its lateral and medial processes (serving as the origins of the abductor hallucis and abductor digiti minimi).
What attaches to the sustentaculum tali?
Several ligamentous structures attach to the sustentaculum tali: plantar calcaneonavicular ligament (anterior surface) deltoid ligament (medial surface) medial talocalcaneal ligament.
What is calcaneum and calcaneus?
The calcaneus, also referred to as the calcaneum, (plural: calcanei or calcanea) is the largest tarsal bone and the major bone in the hindfoot. It articulates with the talus superiorly and the cuboid anteriorly and shares a joint space with the talonavicular joint, appropriately called the talocalcaneonavicular joint.
What does the calcaneus articulate with?
The calcaneus is located in the hindfoot with the talus and is the largest bone of the foot. It is commonly referred to as the heel. It articulates with the talus superiorly and the cuboid anteriorly and shares a joint space with the talonavicular joint, appropriately called the talocalcaneonavicular joint.
What is the function of the sustentaculum tali?
At the upper and forepart of the medial surface of the calcaneus is a horizontal eminence, the sustentaculum tali, which gives attachment to a slip of the tendon of the Tibialis posterior.
What passes under sustentaculum tali?
plantar calcaneonavicular ligament (anterior surface) deltoid ligament (medial surface) medial talocalcaneal ligament.

What ligaments attach to sustentaculum tali?
Several ligamentous structures attach to the sustentaculum tali:
- plantar calcaneonavicular ligament (anterior surface)
- deltoid ligament (medial surface)
- medial talocalcaneal ligament.
