What is the talocalcaneal joint?
Table of Contents
The subtalar joint, also known as the talocalcaneal joint, forms a bridge between the foot and ankle. Located in the hindfoot, it’s the point at which the calcaneus (heel bone) and the talus (a bone at the lower part of the ankle joint) meet.
What type of joint is the talocalcaneal joint?
Plane synovial joint
Subtalar joint
| Type | Plane synovial joint; three degrees of freedom |
|---|---|
| Ligaments | Medial, lateral and posterior talocalcaneal ligaments, interosseous talocalcaneal and cervical ligaments |
| Innervation | Plantar aspect – medial or lateral plantar nerve Dorsal aspect – deep fibular nerve |
What joints are involved in dorsiflexion?
Dorsiflexion occurs in your ankle when you draw your toes back toward your shins. You contract the shinbones and flex the ankle joint when you dorsiflex your foot. You can also dorsiflex your foot by lifting the ball of your foot off the ground while standing, keeping your heel planted into the ground.
Where is talocalcaneal joint?
hindfoot
The talocalcaneal joint, also called the clinical subtalar joint, is an important and complex joint in the hindfoot that allows articulation of the talus and calcaneus.
What are intertarsal joints?
The intertarsal joint are the joints of the tarsal bones in the foot. There are seven specific inter tarsal joints (articulations) in the human foot: Subtalar joint. Talocalcaneonavicular joint. Calcaneocuboid joint.
What joint does dorsiflexion and Plantarflexion?
the ankle joint
The main action of the ankle joint is to allow dorsiflexion and plantar flexion of the foot, as well as some degree of pronation and supination with subtalar and midtarsal joints.
What is the purpose of the mortising machine?
A mortiser or morticer is a specialized woodworking machine used to cut square or rectangular holes in a piece of lumber (timber), such as a mortise in a mortise and tenon joint.
What is a mortise and tenon joint called?
Mortise and Tenon Joints (aka Mortice and Tenon) are the most common and strongest framing joint. They can be used wherever a frame construction is required and have many variations.
What is the STJ?
Subtalar joint functions as a bridge between foot and ankle; transferring loads from foot to tibia or from tibia to foot. It helps the foot to action like a pivot against sudden change of direction.
What type of synovial joint is the Intertarsal joint?
planar joints
Gliding or planar joints are flat or slightly curved and allow only sliding or gliding movements. The intercarpal and intertarsal joints are planar joints.
The talocalcaneal joint, also called the anatomical subtalar joint, is an important and complex joint in the hindfoot that allows articulation of the talus and calcaneus. Gross anatomy. It comprises three articulations between talus and calcaneus 1:
What is the difference between subtalar and talocalcaneal?
The subtalar joint is divided into the talocalcaneonavicular and the talocalcaneal joint, separated by a conical interosseous tunnel (canalis and sinus tarsi). The talocalcaneonavicular joint is a ball-and-socket articulation (coxa pedis).
What connects the talus to the calcaneus?
There are two distinct articulations that connect the talus and calcaneus: the anatomical subtalar (talocalcaneal) joint, located posteriorly, and the more anterior talocalcaneonavicular joint.
What is the function of the talocalcaneal capsule?
This part (also known as the “true” joint capsule) forms the strong talocalcaneal interosseous ligament, together with the anterior part of the talocalcaneal joint capsule. The joint capsule is lined with the synovial membrane which helps to lubricate the joint to facilitate movements of the bones.
