Peroneus (fibularis) longus muscle and Peroneus (fibularis) brevis muscle
The Petronius (fibularis) longus and brevis, fibularis tertius, and the extensor hallicus longus, which helps to support inversion and eversion
posterior tibial
peroneus longus/brevis/tertius
tibialis anterior
Peroneus longus and tibialis anterior are the two muscles that form a stirrup under the foot.
Inversion of the foot is to face the sole of your foot inward toward your midline and eversion is to face the sole of your foot away.
The word 'eversion' means something being turned outward without the change of location. An example is of someone with a club foot being described as having "a foot eversion".
Eversion
Inversion is turning the sole of the foot or ankle medially, and eversion is turning it laterally.
Peroneal group of muscles are involved in eversion joint movement. This compartment lies lateral side of leg. These muscles are supplied by common peroneal nerve.
Eversion is when the foot is curved away from the other foot and is controlled by peroneus longus and peroneus brevis. Inversion is when the foot curves the opposite way, towards the other foot, and is controlled by tibialis anterior and tibialis posterior. The subtalar joint or talocalcaneal joint is the joint that is responsible for creating inversion and eversion in the foot. This joint plays no part in the flexing of the foot though.
Tibialis anterior, Peroneus Longus and Tibialis Posterior. These are the " stirrup" muscles around the ankle and foot to stabilize the ankle in inversion and eversion actions. Thanks, Bing
most commonly injured at the neck of the fibula. injury will cause paralysis of muscles of anterior and lateral compartments of leg along with sensory loss on the skin of the dorsum of the foot. there will be loss of dorsiflexion and that will cause foot drop with patient walking on toes of affected foot. patient will also have difficulty in eversion of the foot with foot remaining in inversion.
Plantar flexion is performed by the muscles of the posterior compartment of the leg, eg gastronemius (mainly) and soleus; other muscles such as plantaris have a weak contribution. The spinal roots are S1 and S2 fibers of the posterior tibial nerve. Foot eversion is performed by the fibularis longus and brevis (both in the lateral compartment of the leg). They are supplied by the superficial peroneal nerve (L5, S1).
Eversion/valgus The deltoid ligament is medial thus it will resist forces that press the foot laterally (prevent eversion).
