Tarsal tunnel syndrome is caused by an inflammation of the tibial nerve that travels just behind the inside ankle bone traveling on to the arch of the foot. Tibial nerve branching in the tarsal tunnel. Tarsal tunnel syndrome: diagnosis, surgical technique, and functional outcome. Outcome of surgical treatment of tarsal tunnel syndrome. An outcomes analysis of surgical treatment of tarsal tunnel syndrome. (2) The second incision is at an angle along the course of the lateral plantar branch of the tibial nerve. (1) The first incision is on the posterior third of the medial aspect of the lower leg along the course of the tibial nerve. Tarsal tunnel syndrome (TTS) involves entrapment of the tibial nerve at the medial ankle beneath the flexor retinaculum and its branches, the medial and lateral plantar nerves, as they course through the porta pedis formed by the deep fascia of the abductor. Symptoms include pain radiating into the foot, usually, this pain is worsened by walking (or weight-bearing activities). The tunnel lies posterior to the medial malleolus of the ankle, beneath the flexor retinaculum. Two incision are involved for a tarsal tunnel release. Tarsal tunnel syndrome (TTS) is a compressive neuropathy of the posterior tibial nerve. It acts as a passageway for tendons, nerves and vessels to travel between the posterior leg and the foot. The patient had pain and numbness in the tibial nerve distribution along with Tinel’s sign and positive scratch collapse at the tarsal tunnel. The tarsal tunnel is a fibro-osseous space located on the posteromedial aspect of the ankle. ![]() In this case, the patient had a traumatic injury to the lower leg, which required open reduction and internal fixation. The tarsal tunnel release involves releasing these structures. There are two primary structures responsible for compression of the tibial nerve: (1) flexor retinaculum and (2) a septum that compartmentalizes the medial and lateral plantar nerves and the overlying fascia of the abductor hallucis muscle. The tibial nerve has three major branches which include the calcaneal, medial plantar, and lateral plantar nerve branches. The Tarsal Tunnel is the canal formed between the bone on your inner ankle (medial malleolus) and a structure that runs across the inside of the ankle and foot. Tarsal tunnel syndrome describes the compression of the tibial nerve through the tarsal tunnel which results in pain and numbness in the plantar aspect of the foot.
