The tarsal tunnel (flexor retinaculum) is found along the inner leg behind the medial malleolus.
The tarsal tunnel is made up of bone on the inside and the flexor retinaculum on the outside.

[edit] Nerve distribution
The tibial nerve, a major artery, veins, and tendons travel in a bundle along this pathway, through the tarsal tunnel.
In the tunnel, the nerve splits into three different paths. One nerve (calcaneal) continues to the heel, the other two (medial plantar nerve and lateral plantar nerve) continue on to the bottom of the foot.
[edit] Contents of tunnel
- Tibialis posterior muscle
- Flexor digitorum longus muscle
- Posterior tibial artery
- Posterior tibial vein
- Tibial nerve
- Flexor hallucis longus muscle
One common mnemonic used to remember the contents is "Tom, Dick and Harry".[1][2][3] or alternatively "Tom, Dick (and very nervous) Harry" if the artery, vein, and nerve are included.
Another common mnemonic used is "Tiny Dogs Are Not Hunters". Bear in mind that tibial veins are located on both sides of tibial artery.
All three muscles are part of the posterior compartment of leg.
