At the upper and forepart of the medial surface of the calcaneus is a horizontal eminence, the sustentaculum tali (alternatively, the talar shelf), which gives attachment to the plantar calcaneo-navicular (spring) ligament, tibiocalcaneal ligament, and medial talocalcaneal ligament.
This eminence is concave above, and articulates with the middle calcaneal articular surface of the talus; below, it is grooved for the tendon of the Flexor hallucis longus; its anterior margin gives attachment to the plantar calcaneonavicular ligament, and its medial margin to a part of the deltoid ligament of the ankle-joint.
[edit] Disease
The sustentaculum is typically involved in subtalar or talocalcaneal tarsal coalition.
