Which 4 movements happen at the ankle joint?
Which 4 movements happen at the ankle joint?
Structure and Function The movements that occur at the ankle joint are plantarflexion, dorsiflexion, inversion, and eversion. The muscles of the leg divide into anterior, posterior, and lateral compartments.
What type of joint is the Tibiotalar joint?
Synovial hinge joint
Ankle joint
| Type | Synovial hinge joint; uniaxial |
|---|---|
| Ligaments | Anterior talofibular, posterior talofibular, calcaneofibular, deltoid (tibiocalcaneal, tibionavicular, tibiotalar parts), fibular collateral ligaments |
| Innervation | Deep fibular (peroneal), tibial and sural nerves |
What type of joint movement is the ankle?
hinged synovial joint
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 is the talus movement?
Together, the talus and calcaneus form the subtalar joint. This joint allows your foot to move inward and outward, which is important for walking on uneven ground. The talus is the main connector between the foot and leg, helping to transfer weight and pressure forces across the ankle joint.
What is Tibiotalar articulation?
The ankle joint (also known as the tibiotalar joint or talocrural joint) forms the articulation between the foot and the leg. It is a primary hinge synovial joint lined with hyaline cartilage.
What joint movements occur between the tarsal bones?
The movement of the transverse tarsal joint is biaxial (around two axes) and triplanar (i.e. occurs in all three cardinal planes). The two axes around which the transverse tarsal joint moves are longitudinal and oblique.
What movements occur at the subtalar joint?
The kinematics of the subtalar joint allows the combined motions of inversion/adduction and eversion/abduction of the rearfoot (Fig. 11.15). (Recall that these motions are components of supination and pronation, respectively.)
How many movements does the ankle have?
In total, the ankle allows the foot to move in six different ways: dorsiflexion, plantarflexion, inversion, eversion, and medial and lateral rotation. Flexion and extension at the ankle are referred to as dorsiflexion and plantarflexion, respectively (Figure 2).
What is dorsiflexion and plantar flexion?
Dorsum (superior surface): Dorsiflexion is the lifting of the front of the foot so that the top of the foot moves toward the anterior leg. Plantar surface (sole): Plantar flexion is the lifting of the heel of the foot from the ground or pointing the toes downward.
What movement is plantar flexion?
The term plantar flexion refers to the movement of the foot in a downward motion away from the body. This movement is crucial in many actions including the everyday action of walking. Conditions such as rheumatoid arthritis and osteoarthritis can reduce plantar flexion and make walking more difficult.
Which movement is an example of dorsiflexion?
Dorsiflexion is where the toes are brought closer to the shin. This decreases the angle between the dorsum of the foot and the leg. For example, when walking on the heels the ankle is described as being in dorsiflexion.
What is plantar and dorsiflexion?
What does dorsiflexion and plantar flexion mean?
Plantar flexion describes foot movement contracting muscles in the sole of the foot while its opposite motion, dorsal flexion or dorsiflexion, describes movement toward the upper side or back.
What 6 movements can be made at the subtalar joint?
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 movements happen at the subtalar joint?
What is dorsiflexion vs plantar flexion?
Dorsiflexion occurs when you lift the forward portion of the foot up (rocking back on your heels with the balls of your feet elevated). Plantarflexion occurs when you push the forward portion of the foot down (raising your heels off the ground as you go up on the balls of your feet).
Does the tibiotalar joint move the ankle?
It is a common misconception that the tibiotalar joint, in addition to allowing up/down motion of the ankle, allows for side to side motion of the ankle in relation to the leg. However, this side to side motion of the ankle is actually a function of the subtalar joint.
What is the anatomy and function of the tibiofibular joints?
The superior tibiofibular joint is a plane synovial joint, while the inferior one is a syndesmosis (fibrous joint). These joints allow no active movements. They do, however, permit a small range of gliding movements that accomodate the movements of the ankle joint. This article will discuss the anatomy and function of the tibiofibular joints.
Where does the anterior tibiotalar ligament pass through the bone?
The ligament passes in front of and across the fibular malleolus (the bony projection at the inside of each ankle) and to the talus bone, which is one of the bones that makes up the lower part of the ankle joint. The anterior tibiotalar ligament is the most commonly sprained ligament.
What are the movements of the calcaneofibular ligament?
The calcaneofibular ligament is the only direct soft tissue connection between the tibiotalar and subtalar joint. The two movements are dorsiflexion and plantarflexion. The axis of rotation for the ankle joint is a line that runs slightly obliquely i.e. not in line with the body.
