Theposteriortubular artery along with themuscularbranches of the sural and peroneal provides the arterial or blood supply to thetibialisposteriormuscle. Origin: Tibia, fibula Insertion: Navicular, medial cuneiform Artery: Posterior tibial artery Nerve: Tibial nerve Action: Inversion of the foot, plantar flexion of the foot at the ankle Antagonist: Tibialis anterior muscle Description: The Tibialis posterior (Tibialis posticus) lies between the two preceding muscles, and is the most deeply seated of the muscles on the back of the leg. Inversion of the foot also has several important functions. The posterior tibial artery supplies the tissues of the posterior compartment of the leg. Its origin is the shaft of the fibula and tibia. Origin. Tibialis posterior Action. Tibialis posterior is involved in movements at two different joints, as follows: Through its action on the ankle joint, tibialis posterior helps the other, more powerful foot flexors to elevate the heel when the foot is planted on the ground. Blood supply to the tibialis posterior muscle is through branches of the posterior tibial artery, which stems the popliteal artery. Any physical injury or damage caused due to the wear and tear of the tendon surrounding the ankle may cause the dysfunction of this muscle. Master the musculoskeletal anatomy and pathology you need to know! Philadelphia: Churchill Livingstone Elsevier, 2010. Neck and back muscle. The tibialis posterior tendon (TPT) is the main dynamic stabilizer of the medial longitudinal arch of the foot. Found inside Page 263Tibialis Posterior Origin : Interosseous membrane adjoining tibia and fibula . Insertion : Navicular , with slips to three cuneiform bones ; cuboid , second The pathology and function of the tendon have been extensively investigated, but knowledge of its insertional anatomy is paramount for surgical procedures. The Tibialis Posterior is located deep in the posterior compartment of the lower leg and situated between the Flexor Digitorium Longus and the Flexor Hallucis Longus. The tendon is the primary regulator of . In more serious conditions the doctor may suggest surgical procedures to repair the damaged tendon or to reconstruct the flat foot. Tendinopathy is probably a more accurate term to use as it refers to wear and tear or degeneration of the tendon rather than acute inflammation. Continuously re-reading and looking at your atlas won't help you remember the origins and insertions. These muscles are located posterior to the tibia, fibula and interosseous membrane. The posterior compartment of the leg is the largest of the three compartments, the muscles in this area act as plantarflex and invert the foot. Function: Flexes the proximal phalanx of the great toe at the metatarsophalangeal joint. See all our videos at http://humanatomy.ca Muscle Name. Flexor hallucis longus origin, insertion, innervation. A total of 118 feet from adult formalin-fixed cadavers were dissected (68 males, 50 females). It forms a tendon which passes behind and under the medial malleolus (the bump on the inside of the ankle) and attaches to the bones of the foot. It is a key stabilising muscle supporting the medial arch of the foot. Origin: Proximal two-thirds of the posterior surfaces of the tibia and the fibula and the interosseous membrane. Tibialis Posterior: Pain & Trigger Points. ), while the plantar flexors (medial gastrocnemius, tibialis posterior, and soleus) and dorsiflexors (tibialis anterior) showed the largest decrease in force over both the full gait cycle and double support (-1228, -1659 .

(2012). It helps to support the arch of the foot. Available from: Semple R, Murley GS, Woodburn J, Turner DE. Further, the sole shall be moved inwards so that the foot comes in inversion position with the toes pointing downwards as in the plantarflexion position. O: posterior surface of the interosseous membrane I: tuberosity of navicular and medial cuneiform N: Tibial nerve. The title of this edition has changed from Radiology of the Foot and Ankle to Imaging of the Foot and Ankle to reflect a greater emphasis on multimodality imaging approaches to solve diagnostic challenges, specifically the increased use of If the condition is not severe, certain simple exercises as suggested by the physician helps a lot in relieving the pain as well in improving the movement of the foot in case of tibialis posterior dysfunction. It may cause instability while walking. It supports the longitudinal arch and serves as an ankle plantar flexor and hindfoot invertor. Muscles Moving Ankle / Foot / Toes - Posterior Flexor hallicus longus ORIGIN: proximal tibia / fibula INSERTION: tarsals; metatarsals 2 - 4 INNERVATION: tibial nerve ACTION: inverts foot (Posterior view) Muscles Moving Ankle / Foot / Toes - Posterior Tibialis posterior The anterior tibial artery travels between the medial and lateral parts of the muscle, close to its origin points. It is one of the terminal branches of the popliteal artery. The belly of the muscle is overlapped by the flexor hallucis longus and flexor digitorum longus muscles.

Kim Bengochea, Regis University, Denver, Author: Especially in adult acquired flatfoot deformity (AAFD) the TPT plays a detrimental role. important to know that the ACL origin lies behind a small. It has been suggested that the tibialis posterior muscle also raises the medial arch slightly, rather than having a direct effect on the hindfoot [1 . Together with popliteus, flexor hallucis longus and flexor digitorum longus, it forms the deep group of muscles of the posterior compartment of leg. Grays Anatomy for Students, 3rd Edition, Churchill Livingston Elsevier, Moore, K.L., Agur, A.M.R., Dalley, A.F. Actions: - plantar flexion - inversion of the foot Posterior It runs from back of knee to the ankle and is multipennate. It travels through the popliteal fossa, giving off branches to muscles in the superficial posterior compartment of the leg. This results in flattening of the foot. It is a key stabilising muscle supporting the medial arch of the foot. Supports medial longitudinal arch of foot Tibialis posterior origin, insertion, innervation. While in PTTD the damage is caused to the muscle itself. Vogl, A.W., Mitchell, A.W. O: posterior surface of fibular I: distal phalanx of great toe Holds up medial longitudinal arch of foot: NERVE Tibialis posterior (L5) Splits into two slips after passing inferior to plantar calcaneonavicular ligament; superficial slip inserts on the tuberosity of the navicular bone and sometimes medial cuneiform; deeper slip divides again into slips inserting on plantar surfaces of metatarsals 2 - 4 and second cuneiform.

Flexor hallucis longus origin, insertion, innervation. Posterior Tibial Exercises with Dr. Leo Kormanik. ; insertion: navicular and medial cuneiform . The small tibialis posterior (not clearly shown on the above image) lies beneath the flexor digitorum longus and between the flexor digitorum longus and flexor hallucis longus.
