Located in the deep posterior compartment of the leg.
The tibialis posterior muscle is a relatively small muscle located within the back side of the calf. The primary function of this muscle is to provide stability to the lower leg. It also facilitates foot inversion (swiveling inward) and aids the ankle's plantar flexion (flexing the foot or toes downward). Additionally, the muscle performs a key role in providing support to the foot's medial arch. Click to read more below. The tibialis anterior muscle is a long, narrow muscle in the anterior compartment of the lower leg. Arising from origins along the lateral condyle and proximal body of the tibia, it runs down the shin just lateral to the tibia Tibialis Posterior. The tibialis posterior originates on your tibia and fibia bones and inserts near the inner arches of your feet. What makes this muscle significant is that it works together with the tibialis anterior and the peroneal muscles to create a type of sling for the arches of your feet. The tibialis posterior is the most central of all the leg muscles, and is located in the deep posterior compartment of the leg. It is the key stabilizing muscle of the lower leg. Blood is supplied to the muscle by the posterior tibial artery, and innervation is via the tibial nerve. The tendon of the tibialis posterior muscle (sometimes called the posterior tibial tendon) descends posterior to the medial malleolus and terminates by dividing into plantar, main, and recurrent components. Tibialis anterior. The tibialis anterior muscle is the largest muscle located in the anterior (front) compartment of the leg. The blood supply to the tibialis anterior muscle comes primarily from the anterior tibial artery and its branches. The muscle inserts into the base of the first metatarsal bone in the foot, located just behind the big toe. It also inserts to the medial and inferior surfaces of the medial cuneiform tarsal. The tibialis anterior muscle helps with dorsiflexion, which is the action of pulling the foot toward the shin. Tibialis posterior. The tibialis posterior muscle is a relatively small muscle located within the back side of the calf. It is also the most centrally located muscle in the leg, arising from the inner borders of the fibula and tibia on the posterior (rear) side. The primary function of this muscle is to provide stability to the lower leg. It also facilitates foot inversion (swiveling inward) and aids the ankle's plantar flexion (flexing the foot or toes downward). Additionally, the muscle performs a key role in providing support to the foot's medial arch. Tibialis posterior, the most important stabilizing muscle in your lower leg, is located behind the tibia (shin bone). The tendon of tibialis posterior runs behind the medial malleolus (inside ankle bone) and into the arch of the foot. The pain is located on the inside of the ankle or arch of the foot and gradually worsens with repetitive stress. TREATMENT. Since tibialis posterior shares a role in controlling foot pronation along with soleus (one of the calf muscles), strengthening the tibialis posterior muscle and soleus are critical for treatment. The posterior tibialis muscle is located underneath the calf muscles of the lower leg and runs from the back of the knee to navicular bone in your foot. Its origin is around the top of the tibia and fibula bones in the leg. The posterior tibial tendon is located in the lower leg and assists with several important functions of the foot. Unfortunately, the posterior tibial tendon is prone to weakness and can be responsible for conditions such as flat feet or inward collapsing of the ankles.
