Depending on the severity of the condition, one of several surgical options may be recommended, including:
Tarsal Tunnel Release
The procedure to release the flexor retinaculum can usually be done using either a spinal type anesthetic or a general anesthetic. Once you have anesthesia, your surgeon will make sure the skin of your leg and ankle are free of infection by cleaning the skin with a germ-killing solution.
The surgeon then makes a small incision in the skin behind the inside ankle bone (medial malleolus). The incision is made along the course of the tibial nerve where it curves behind the malleolus. The nerve is located and released by cutting the flexor retinaculum. The surgeon will then surgically follow the nerve into the foot, making sure the nerve is free of pressure throughout its course.
The flexor retinaculum is left open to give the nerves more space. Eventually, the gap between the two ends of the flexor retinaculum fills in with scar tissue. Following surgery, the skin is repaired with stitches.
