Classification of ankle joint
How many types of ankle joints are there?
three joints
The ankle is composed of three joints: the talocrural joint (also called talotibial joint, tibiotalar joint, talar mortise, talar joint), the subtalar joint (also called talocalcaneal), and the Inferior tibiofibular joint. The joint surface of all bones in the ankle are covered with articular cartilage.
Is the ankle a Condyloid joint?
Ankle and Foot Joints
Hinge joints in the ankle, which allow flexion (bending) and extension. Gliding joints found in the hindfoot, which allow gliding movements. Condyloid joints found in the forefoot and toes, which allow the flexion (bending) and extension, adduction and abduction (sideward movement).
What type of joint is the ankle and wrist?
(1) Gliding joints move against each other on a single plane. Major gliding joints include the intervertebral joints and the bones of the wrists and ankles.
What are the 4 primary movements of 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.
Is ankle a hinge 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).
Is the ankle joint a saddle joint?
Example of hinge joints is the ankle, elbows, and knee joints. Saddle joint is the biaxial joint that allows the movement on two planes–flexion/extension and abduction/adduction. For example, the thumb is the only bone within the physical body having a saddle joint.
What is the ankle joint called?
Talocrural joint
The ankle joint, or Talocrural joint, is a large synovial joint. It is a hinge joint that allows plantarflexion and dorsiflexion, moving the foot up and down. The ankle is more stable while joint is in dorsiflexion, and the anterior part of the talus is held in the joint.
What are the 5 ranges of motion of the ankle?
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 are the 6 main ligaments of the ankle 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 |
Which joints are condyloid joints?
An example of condyloid joints is the wrist. Condyloid joints are also found in the hands and allow for the movement of fingers.
What is the joint in the ankle called?
Talocrural joint
The ankle joint, or Talocrural joint, is a large synovial joint. It is a hinge joint that allows plantarflexion and dorsiflexion, moving the foot up and down. The ankle is more stable while joint is in dorsiflexion, and the anterior part of the talus is held in the joint.
What are some examples of condyloid joints?
Examples
- radiocarpal joint of the wrist.
- metacarpophalangeal joints of the hand.
- metatarsophalangeal joints of the foot.
What type of joint is a condyloid joint?
A condyloid joint is a modified ball and socket joint that allows for flexion, extension, abduction, and adduction movements.
What are the 7 ankle bones called?
tarsal bones
The tarsal bones are 7 in number. They are named the calcaneus, talus, cuboid, navicular, and the medial, middle, and lateral cuneiforms.
What is the function of the ankle joint?
The ankle joint allows up-and-down movement of the foot. The subtalar joint sits below the ankle joint, and allows side-to-side motion of the foot. Numerous ligaments (made of tough, moveable tissue) surround the true ankle and subtalar joints, binding the bones of the leg to each other and to those of the foot.
