Surgery for the tarsal tunnel should only be considered if all non-operative treatment options have not been successful at relieving pain and other symptoms. The surgery is conducted to relieve the pressure on the posterior tibial nerve and its branches.

The operation requires an incision that is made from just below the ankle bone (medial malleolus -- shown in green), and that continues in a gentle s-shaped curve to the beginning of the arch of your foot. (Below: incision shown by black dashed line)
