What joint does dorsiflexion occur?
ankle 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.

What joint does dorsiflexion and plantarflexion?
Overview. The ankle joint is a hinged synovial joint with primarily up-and-down movement (plantarflexion and dorsiflexion). However, when the range of motion of the ankle and subtalar joints (talocalcaneal and talocalcaneonavicular) is taken together, the complex functions as a universal joint (see the image below).
What type of joint is the Talocrural joint?
synovial joint
The ankle joint (or talocrural joint) is a synovial joint located in the lower limb. It is formed by the bones of the leg (tibia and fibula) and the foot (talus). Functionally, it is a hinge type joint, permitting dorsiflexion and plantarflexion of the foot.
What two joints form the Talocrural joint?
The talocrural joint is formed between the distal tibia-fibula and the talus, and is commonly known as the ankle joint. The distal and inferior aspect of the tibia – known as the plafond – is connected to the fibula via tibiofibular ligaments forming a strong mortise which articulates with the talar dome distally.
What bones make up the Talocrural joint?
Three bones come together to form the talocrural joint: the tibia and fibula in the lower leg, and the talus in the foot. Held together by strong ligaments, the tibia and fibula form a bracket-shaped socket (mortise).
Is the Talocrural joint uniaxial?
In the ankle (talocrural) joint, the lower end of the tibia and fibula embrace the trochlea tali. Thus, an approximately uniaxial joint is formed which permits dorsiflexion and plantarflexion of the foot against the leg. Limitation of movements is due to leg muscles as well as strong ligaments.
What’s the ankle bone called?
talus
The talus (or “ankle bone”) connects your leg to your foot.
Which articulations are found in the Talocrural joint?
The talocrural joint (TCJ) (articulation between tibia, fibula, and talus, connecting the foot to the lower leg) has a triplanar axis of rotation.
What’s concentric and eccentric?
In a concentric contraction, the muscle tension rises to meet the resistance then remains stable as the muscle shortens. During eccentric contraction, the muscle lengthens as the resistance becomes greater than the force the muscle is producing.
What type of joint is the talocrural joint?
The talocrural joint is a uniaxial synovial joint connecting the distal tibia to the talus. While many people view the talocrural joint as only a hinge joint, others authors argue that it is more complex due to the composite internal and external rotation that occurs during dorsiflexion and plantarflexion respectively.
Where is the posterior talofibular ligament located?
The posterior talofibular ligament on the dorsal part of the distal lower leg. An important ligament in the ankle joint is the deltoid ligament which is composed of the tibiocalcaneal, tibionavicular and tibiotalar part. It is located at the medial side of the ankle joint.
What bone articulates with the talus?
The talus articulates with FOUR seperate bones- the tibia, fibula, calcaneus, and navicular bones. The superior articulation between the talus and tibia/fibula is known as the talocrural joint. The talocrural joint is a uniaxial synovial joint connecting the distal tibia to the talus.
What is the function of the calcaneofibular ligament?
The calcaneofibular ligament is the only ligament bridging both the talocrural joint and subtalar joint. Insertion of this ligament and its axis of rotation point allow flexion and extension movements of the talocrural joint. Depending on its bi-articular characteristic, this ligament also permits subtalar movement.
