"The flexor retinaculum at the ankle is formed by reinforcement of the deep fascia of the leg by transverse collagen bundles and functions to prevent 'bowstringing' of the flexor tendons (tibialis posterior, flexor digitorum longus, and flexor hallucis longus) as they pass the tibiotalar joint. It forms the roof of the tarsal tunnel 1-2."
