Tarsal tunnel

Tarsal tunnel
The mucous sheaths of the tendons around the ankle. Medial aspect.
Latin Canalis tarsi

The tarsal tunnel 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.

Nerve distribution

The tibial nerve, posterior tibial 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.

Tarsal tunnel syndrome is the most commonly reported nerve entrapment of the ankle and is analogous to the carpal tunnel of the wrist. People with tarsal tunnel syndrome have pain in the plantar aspect of the foot mostly at night. Weight bearing increases pain and weakness is found on intrinsic foot muscles with positive Tinel sign at the tunnel. There is no tenderness present on the plantar foot, though this is typically the primary site of complaint.

Mnemonic

One common mnemonic used to remember the contents from anterior to posterior 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. A further memory aid, used extensively at St George's Hospital Medical School in London, is Tom Drives A Very Nervous Horse.

A very similar mnemomic taught at some medical schools is "Tom Dick And Very Naughty Harry" or alternatively "Tom Dick And Very Nervous Harry".
