Muscular Abnormalities as a Cause of the Tarsal Tunnel Syndrome: An Infrequent Bilateral Clinical Case

A clinical case of a female patient affected by bilateral tarsal tunnel syndrome is described. The peculiarity of this case is the difference in the observed anatomopathological muscular abnormalities between the two feet. On one side, an accessory muscular venter of the toes’ long flexor was identified. On the other side, posterior tibial nerve compression was determined by an accessory venter of the hallux long flexor, associated with an abnormal venter of the toes’ long flexor, with a minor extent if compared to contralateral findings.
