Foot Muscles: The muscles working on the foot can be distributed within the extrinsic and intrinsic. They are chiefly liable for actions such as inversion, eversion, plantar flexion, and dorsiflexion of the foot. Conservative treatment of tibialis posterior tendon dysfunction-A review. The extrinsic Foot Muscles: The muscles of the foot can be separated into two distinct groups extrinsic and intrinsic muscles. Journal of the American Podiatric Medical Association, 101(2), pp.176-186. Large forefoot abduction instead of large rearfoot eversion during walking might be the indicator of. Strengthening foot muscles may contribute to injury prevention in pronators. Posterior tibial tendon dysfunction: a review. There are differences in both extrinsic and intrinsic foot muscle morphology between symptomatic and asymptomatic pronators in a physically active adult population.

It usually presents with pain on the medial side of the ankle. Injury to the distal tendon of the tibialis posterior muscle is rare. Dysfunction of the tibialis posterior, including rupture of the tibialis posterior tendon, can lead to flat feet in adults, as well as a valgus deformity due to unopposed eversion when inversion is lost.

The tibialis posterior has a major role in supporting the medial arch of the foot. It also contracts to produce inversion of the foot, and assists in the plantarflexion of the foot at the ankle. The tibialis posterior muscle is a key muscle for stabilization of the lower leg. The tibialis posterior muscle is suppled by the tibial nerve. The recurrent portion inserts into the sustentaculum tali of the calcaneus.īlood is supplied to the muscle by the posterior tibial artery. The plantar portion inserts into the bases of the second, third and fourth metatarsals, the intermediate and lateral cuneiforms and the cuboid. The smaller portion inserts into the plantar surface of the medial cuneiform. The main portion inserts into the tuberosity of the navicular bone. It terminates by dividing into plantar, main, and recurrent components. The tendon of the tibialis posterior muscle (sometimes called the posterior tibial tendon) descends posterior to the medial malleolus. It is also attached to the interosseous membrane medially, which attaches to the tibia and fibula. They are mainly responsible for actions such as eversion. The tibialis posterior muscle originates on the inner posterior border of the fibula laterally. The extrinsic muscles arise from the anterior, posterior and lateral compartments of the leg.
