Tibialis Posterior Rupture; Shin Splints; Tibialis Posterior Tendon Dysfunction (TPTD) is thought to be the likely cause in most cases of adult acquired flatfoot. This occurs when increased pressure builds up within the muscle compromising the blood supply and nerve supply. The fibular nerve, or deep peroneal nerve, originates above the back of the knee and innervates part of the hamstring muscles, coming down to the lateral side of the gastrocnemius. The sural nerve is a cutaneous branch of the tibial nerve that supplies the skin of the legs and feet. http://www.dartmouth.edu/~humananatomy/figures/chapter_15/15-10.HTM, http://www.dartmouth.edu/~humananatomy/figures/chapter_17/17-3.HTM, https://en.wikipedia.org/w/index.php?title=Anterior_tibial_artery&oldid=1071812709, Anatomy NAV infobox with use of other NAV parameters, Creative Commons Attribution-ShareAlike License 3.0, This page was last edited on 14 February 2022, at 13:24.
