What type of joint is subtalar?
What type of joint is subtalar?
Subtalar joint
Type | Plane synovial joint; three degrees of freedom |
---|---|
Articular surfaces | Posterior calcaneal facet on the posterior part of the inferior surface of the talus; Posterior facet on the superior surface of the calcaneus |
What action does the talocalcaneal joint have?
The ankle joint, known as the talocrural joint, is primarily responsible for dorsiflexion and plantar flexion. But the subtalar joint also plays a small role in these motions.
What are the movements of the Talocrural joint?
For the purpose of this post, the primary movements at the talocrural joint are plantarflexion and dorsiflexion. The average individual has approximately 15-20 degrees of dorsiflexion and 50 degrees of plantarflexion. These motions are often limited due to inadequate stress and load through the joint.
Where is the talocalcaneal joint?
foot
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. Ligaments of the medial aspect of the foot. The joint is classed structurally as a synovial joint, and functionally as a plane joint.
How is the subtalar joint best classified?
Clinically, subtalar joint movement is classified as inversion-eversion. The other components, e.g. anteroposterior (AP) and mediolateral translation are not assessable on clinical examination. Range of movement is in the range of 25° to 30° in inversion and 5° to 10° in eversion, respectively.
What is talocalcaneonavicular joint?
The talocalcaneonavicular joint is a ball and socket joint; the rounded head of the talus is received into the concavity formed by the posterior surface of the navicular, the anterior articular surface of the calcaneus, and the upper surface of the plantar calcaneonavicular ligament.
What is Talocalcaneal ligament?
The lateral talocalcaneal ligament (LTCL) is a short yet sturdy bundle of muscle fibers found in the human ankle. The lateral talocalcaneal ligament stretches from the lateral (outer-side) portion of the talus, or ankle bone, to the lateral surface of the calcaneus, or heel bone.
What type of joint is the Talocrural joint?
Synovial hinge joint
The ankle joint, also known as the talocrural joint, is a synovial joint that connects the bones of the leg, the fibula and tibia, with the talus of the foot. It is a complex hinge joint composed of two articulations….Ankle joint.
Type | Synovial hinge joint; uniaxial |
---|---|
Movements | Dorsiflexion, plantar flexion |
Is Talocrural joint concave on convex?
The posterior talocalcaneal joint is formed by a concave surface of the talus and a convex surface of the calcaneus. The subtalar joint contributes to the dorsiflexion of the ankle. Three articulating facets (anterior, middle and posterior) are present between the talus and the calcaneus.
What is the chopart joint?
The Chopart joint complex, also known as the midtarsal or transverse tarsal joint, is located between the hindfoot and midfoot and consists of the talocalcaneonavicular and calcaneocuboid joints.
Is subtalar joint small or intermediate?
intermediate joints
Response: I think of ankle, subtalar, talo-navicular and calcaneo-cuboid joints as intermediate joints (CPT 20605). Joints distal to those I consider to be small joints.
