Abstract

6. Posterior Tarsal Tunnel Syndrome. Gonzalez J(1), Bergman R(2), Gibboney MD(3). In: StatPearls [Internet]. Treasure Island (FL): StatPearls Publishing; 2026 Jan–. 2026 May 24. Author information: (1)Western University Of Health Sciences (2)Northwestern University Feinberg School of Medicine (3)Naval Medical Center Camp Lejeune Koppel and Thompson first described anterior tarsal tunnel syndrome (ATTS) in 1960. ATTS, also known as deep peroneal nerve (DPN) entrapment, is a compression neuropathy of the DPN most commonly caused by a tight fascial band in the anterior ankle known as the inferior extensor retinaculum. Two other anatomic locations of entrapment have been described and include deep to the extensor hallucis longus tendon over the talonavicular joint and deep to the extensor hallucis brevis muscle overl the first and second tarsometatarsal joints. The deep peroneal nerve is 1 of 2 terminal branches off the common peroneal nerve (CPN). The deep peroneal nerve (DPN) branches from the common peroneal nerve (CPN) near the fibular neck, then enters the anterior compartment and travels distally along the interosseous membrane toward the ankle. Just proximal to the ankle joint, the DPN courses under the inferior extensor retinaculum between the extensor hallucis longus tendon and the extensor digitorum longus tendon. The DPN then divides into the medial and lateral terminal branches. The EDB and EHB muscles are innervated by the lateral terminal branch of the DPN, while the medial branch runs beside the dorsalis pedis artery in the dorsal foot and is purely sensory, providing innervation to the first webspace. In the anterior leg, the DPN provides motor innervation to the tibialis anterior, extensor digitorum longus (EDL), peroneus tertius, and extensor hallucis longus (EHL) muscles. The anterior tarsal tunnel is a fibro-osseous tunnel along the anterior ankle in which the borders include the inferior extensor retinaculum (superficially/roof), medial malleolus (medially), lateral malleolus (laterally), and the talonavicular joint capsule (deep/floor). Contents of the anterior tarsal tunnel include the dorsalis pedis artery and vein, deep peroneal nerve, tibialis anterior tendon, extensor hallucis longus tendon, extensor digitorum longus tendon, and peroneus tertius (see Image. Anatomic Structures of the Anterior Ankle). The common peroneal nerve receives contributions from the L4 through S2 nerve roots. Copyright © 2026, StatPearls Publishing LLC.
