tarsal tunnel syndrome
Tarsal tunnel syndrome is a compression, or squeezing, on the posterior tibial nerve that produces symptoms anywhere along the path of the nerve running from the inside of the ankle into the foot. Tarsal tunnel syndrome is similar to carpal tunnel syndrome, which occurs in the wrist. Both disorders arise from the compression of a nerve in a confined space. Causes. Tarsal tunnel syndrome is caused by anything that produces compression on the posterior tibial nerve, such as: A person with flat feet is at risk for developing tarsal tunnel syndrome, because the outward tilting of the heel that occurs with âfallenâ arches can produce strain and compression on the nerve.
