What is the function of interosseous Talocalcaneal ligament?
Anatomical terminology The interosseous talocalcaneal ligament forms the chief bond of union between the talus and calcaneus.
What is the Talocalcaneal ligament?
The lateral talocalcaneal ligament (external calcaneo-astragaloid ligament) is a ligament in the ankle. It is a short, strong fasciculus, passing from the lateral surface of the talus, immediately beneath its fibular facet to the lateral surface of the calcaneus.
What action does the Talocalcaneal joint have?
Subtalar joint
| Type | Plane synovial joint; three degrees of freedom |
|---|---|
| Innervation | Plantar aspect – medial or lateral plantar nerve Dorsal aspect – deep fibular nerve |
| Blood supply | Posterior tibial artery, fibular artery |
| Movements | Inversion/eversion, abduction/adduction, plantarflexion/dorsiflexion (gliding and rotation) |
What is the function of the collateral ligament of the ankle?
About the lateral collateral ligament It connects the thighbone (femur) to the fibula, which is the small bone of the lower leg that runs down the side of the knee and connects to the ankle. Like the medial collateral ligament, the lateral collateral ligament’s main function is to keep the knee stable.
What are deltoid ligaments?
The Deltoid ligament (or the medial ligament of talocrural joint) is a strong, flat and triangular band. It is made up of 4 ligaments that form the triangle, connecting the tibia to the navicular, the calcaneus, and the talus . It is attached above to the apex and anterior and posterior borders of the medial malleolus.
Where is the lateral Talocalcaneal ligament?
The lateral talocalcaneal ligament is a short, strong fasciculus, passing from the lateral surface of the talus, immediately beneath its fibular facet to the lateral surface of the calcaneus. It is placed in front of, but on a deeper plane than, the calcaneofibular ligament, with the fibers of which it is parallel.
Which ligament is also referred to as the spring ligament?
The plantar calcaneonavicular ligament also referred to as spring ligament is a thick wide band of cartilaginous connective tissue that supports the medial longitudinal arch of the foot, failure in the spring ligament leads to flat foot deformity.
What type of joint is the talocalcaneal?
In human anatomy, the subtalar joint, also known as the talocalcaneal joint, is a joint of the foot. It occurs at the meeting point of the talus and the calcaneus. The joint is classed structurally as a synovial joint, and functionally as a plane joint….

What ligaments are on the lateral aspect of the ankle?
The lateral ligaments of the ankle, composed of the anterior talo-fibular ligament (ATFL), the calcaneo-fibular ligament (CFL) and the posterior talo-fibular ligament.
What is the lateral ligament in the ankle?
The lateral collateral ligament (complex) of the ankle is a set of three ligaments that resist inversion of the ankle joint. They are more commonly injured than the medial collateral (deltoid) ligament of the ankle. They run from the lateral malleolus of the fibula to the talus and calcaneus.
What is lateral side of ankle?
The true ankle joint is composed of three bones, seen above from a front, or anterior, view: the tibia which forms the inside, or medial, portion of the ankle; the fibula which forms the lateral, or outside portion of the ankle; and the talus underneath.
Where is the lateral talocalcaneal ligament located on the body?
The lateral talocalcaneal ligament is a short, strong fasciculus, passing from the lateral surface of the talus, immediately beneath its fibular facet to the lateral surface of the calcaneus. It is placed in front of, but on a deeper plane than, the calcaneofibular ligament, with the fibers of which it is parallel.
Is the anterior and posterior facets of the talocalcaneal joint the same?
The anterior talo-calcaneal articulation (anterior and middle facets) are often congruent and are part of a separate synovial cavity (talocalcaneonavicular joint) to the posterior talocalcaneal articulation. The posterior talocalcaneal articulation (posterior facet) only, comprises the anatomical subtalar joint. 1.
What is the articulation between the talus and calcaneus?
The anatomical subtalar joint is a synovial articulation between the talus and calcaneus. It consists of two articular facets lined with the hyaline cartilage.
How are the bones of the subtalar joint held together?
The anatomical subtalar joint is a single synovial articulation formed between the posterior calcaneal articular facet of the talus and the convex posterior articular facet of the calcaneus. These bones are held together by the fibrous capsule, medial talocalcaneal, lateral talocalcaneal, interosseous talocalcaneal and cervical ligaments.
