• tendons
  • The posterior tibial artery, tibial nerve, and tendons of the tibialis posterior, flexor digitorum longus, and flexor hallucis longus muscles travel in a bundle through the tarsal tunnel. (wikipedia.org)
  • nerve
  • Tarsal tunnel syndrome ( TTS ), also known as posterior tibial neuralgia , is a compression neuropathy and painful foot condition in which the tibial nerve is compressed as it travels through the tarsal tunnel . (wikipedia.org)
  • Inside the tunnel, the nerve splits into three different segments. (wikipedia.org)
  • The flexor retinaculum has a limited ability to stretch, so increased pressure will eventually cause compression on the nerve within the tunnel. (wikipedia.org)
  • Flat feet may cause an increase in pressure in the tunnel region and this can cause nerve compression. (wikipedia.org)
  • Back problems with the L4, L5 and S1 regions are suspect and might suggest a "Double Crush" issue: one "crush" (nerve pinch or entrapment) in the lower back, and the second in the tunnel area. (wikipedia.org)
