Structures pass behind the medial malleolus beneath the flexor retinaculum. From anteromedial to posterolateral, which structure occupies the most posterior position immediately adjacent to the medial malleolus-retinaculum complex?

• A Tendon of tibialis posterior
• B Tendon of flexor hallucis longus ✓
• C Posterior tibial artery
• D Tendon of flexor digitorum longus

Explanation

The order from anteromedial to posterolateral follows the mnemonic Tom, Dick, And Very Nervous Harry: tibialis posterior, flexor digitorum longus, posterior tibial artery, tibial nerve, and flexor hallucis longus. The flexor hallucis longus tendon is the most posterior and actually grooves the posterior process of the talus, which distinguishes it from the more anterior tibialis posterior tendon.
