The laciniate ligament (internal annular ligament flexor retinaculum of foot) is a strong fibrous band extending from the tibial malleolus above to the margin of the calcaneus below converting a series of bony grooves in this situation into canals for the passage of the tendons of the Flexor muscles and the posterior tibial vessels and tibial nerve into the sole of the foot.
