You may be familiar with the term carpal tunnel syndrome, a condition in the wrist where a nerve gets pinched. Tarsal tunnel syndrome is a similar condition. The main nerve under the foot gets compressed behind the ankle. This leads to a wide spectrum of symptoms including burning, tingling, numbness, aching and pain behind the ankle and under the arch of the foot. Unfortunately, the results of this type of surgery are not very predictable, and only 80% of patients will experience a full recovery. Recurrence of symptoms with burning and tingling can occur, and rarely, your pain can be worse after this surgery.

What is tarsal tunnel surgery?

A cut is made behind the ankle, about 6-8 cm in length
The deeper tissues are opened, and the lining of the nerve is released
The nerve divides into a number of main branches, and for each nerve branch, the tight covering or retinaculum is released and the pressure on the nerve is relaxed.
Some surgeons open the nerve itself, however this is not part of the surgery which I will do, since this increase scarring on the nerve after surgery.
