what plane does eversion occur in
It is classified as a uniaxial joint, allowing movement in the sagittal plane only: dorsiflexion and plantar flexion. Inversion and eversion of the foot in the frontal plane does not occur at the ankle joint, but occurs primarily at the subtalar joint â the articulation between the talus and the calcaneus. Several other intertarsal joints are involved in inversion and eversion as well. Muscles on the front of the ankle will typically cause dorsiflexion, while muscles on the back of the ankle will typically cause plantar flexion. Muscles that pass on the lateral aspect of the ankle joint will typically cause eversion of the subtalar joint while muscles that pass on the medial aspect of the ankle joint will typically cause inversion of the subtalar joint.
