Posterior Talocalcaneal Ligament, Posterior View

Description

Positioned on the posterior aspect of the subtalar region, the posterior talocalcaneal ligament spans from the posterolateral talus (near the posterior process) to the superior posterior calcaneus, crossing the back of the talocalcaneal joint in short, obliquely oriented fibers. The distal tibia and fibula form the ankle mortise superiorly, with the talus seated between the malleoli and the calcaneus lying inferior and slightly posterior as the heel. A narrow fat-filled interval between talus and calcaneus corresponds to the posterior part of the sinus tarsi and tarsal canal region, adjacent to the posterior subtalar joint line. Posterior subtalar restraints are easy to hand-wave in teaching, but they matter when you are explaining hindfoot stability and subtalar arthrokinematics. The posterior talocalcaneal ligament limits excessive posterior translation and rotational play between talus and calcaneus during inversion and eversion, and it sits close to structures targeted in hindfoot arthroscopy and subtalar arthrodesis, where posterior portals and screw trajectories demand a clean mental map of what lies between the talar process and calcaneal tuberosity. Pain after an ankle sprain is not always tibiotalar. Persistent hindfoot symptoms can reflect subtalar ligament injury patterns or post-traumatic subtalar instability. Orthopedic texts and surgical atlases use this posterior perspective to orient readers before describing the posterior approach to the subtalar joint, fixation across the talocalcaneal articulation, or debridement in posterior hindfoot arthroscopy. It also fits well in gross anatomy lab guides and lower-limb biomechanics modules when you need a single plate that clarifies how the talus, calcaneus, and their short connective tissue bands relate in the deep posterior ankle.
