What motion occur at the subtalar joint?
What motion 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.)
What is subtalar motion?
Subtalar joint motion (pronation or supination) occurs around a single, oblique axis (pictured here for the left foot). Because the joint’s axis is oblique, we observe a component of subtalar motion no matter which of the three reference planes (sagittal, frontal, or transverse) that we use as our point of view.
Which direction does the subtalar joint allow the foot to move?
With regard to the subtalar joint, its articulated structure enables the inversion or eversion of your foot. 1 While inversion and eversion are components of pronation and supination, respectively, they specifically involve the hindfoot rather than the entire foot. With inversion, you rotate your ankle inward.
How many planes of movement does the subtalar joint permit?
The talocrural joint allows motion in the sagittal plane: dorsiflexion and plantar flexion. The subtalar joint allows an oblique arc of motion that results primarily in the combined motions of inversion and adduction, or eversion and abduction—two of the three components of supination and pronation, respectively.
What is the subtalar joint responsible for?
Function. The joint allows inversion and eversion of the foot, but plays minimal role in dorsiflexion or plantarflexion of the foot. The centre of rotation of the subtalar joint is thought to be in the region of the middle facet. It is considered a plane synovial joint, also commonly referred to as a gliding joint.
Is the subtalar joint a gliding joint?
It is considered a plane synovial joint, also commonly referred to as a gliding joint. It acts as a hinge connecting the talus and calcaneus.
What muscle passes behind the medial malleolus?
Flexor digitorum longus
Flexor digitorum longus – The flexor digitorum longus muscle is, as the name implies, a long one. It is a flexor of the digits, meaning it passes behind the medial malleolus and attaches inferiorly to the phalanges. The muscle attaches proximally on the middle-third of the medial aspect of the tibia.
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 type of joint is the subtalar joint?
Plane synovial joint
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 |
How do you heal a subtalar joint?
Treating your subtalar joint pain Medication, including steroid injections, can reduce pain and inflammation. Along with these conservative measures, patients will be encouraged to rest the foot and use proper supportive footwear. These measures can help many with pain heal naturally and return to normal activities.
