The tibialis anterior muscle is the most medial muscle of the anterior compartment of the leg. [1] [better source needed] The muscle ends in a tendon which is apparent on the anteriomedial dorsal aspect of the foot close to the ankle. [citation needed] Its tendon is ensheathed in a synovial sheath.
A compartment space is anatomically determined by an unyielding fascial (and osseous) enclosure of the muscles.The anterior compartment syndrome of the lower leg (often referred to simply as anterior compartment syndrome), can affect any and all four muscles of that compartment: tibialis anterior, extensor hallucis longus, extensor digitorum longus, and peroneus tertius.
Lace bite is an irritation of the tibialis anterior and toe extensor tendons. [1] The medical term for the condition is "tibialis anterior tendinopathy." [2] This irritation, felt on the front of the foot or ankle, is often experienced by ice hockey players and figure skaters. It is caused by friction between the tendon and tongue of the ice ...
Plus, since the tibialis anterior is very important for lifting to foot during the gait cycle, strengthening this muscle can even help older adults reduce trip risk, adds Tavel.
Common nerve injuries that are treated with tendon transfer surgery are spinal cord, radial nerve, ulnar nerve, or median nerve injury. Tendon transfers have higher chance to treat nerve palsy, and such transfers include posterior, anterior, and anteroposterior tibial tendon transfer.
Enumerated from the medial side, the four canals which it forms transmit the tendons of the tibialis posterior and flexor digitorum longus muscles; the posterior tibial artery and tibial nerve, which run through a broad space beneath the ligament; and lastly, in a canal formed partly by the talus, the tendon of the flexor hallucis longus.
The lateral surface is narrower than the medial; its upper two-thirds present a shallow groove for the origin of the Tibialis anterior; its lower third is smooth, convex, curves gradually forward to the anterior aspect of the bone, and is covered by the tendons of the Tibialis anterior, Extensor hallucis longus, and Extensor digitorum longus ...
It contains the anterior tibial artery and vein and the tendons of the tibialis anterior muscle within its tendon sheath and the unsheathed tendons of extensor hallucis longus and extensor digitorum longus muscles. The deep peroneal nerve passes under the retinaculum while the superficial peroneal nerve is outside of it.
