An os sustentaculi with an accompanying talocalcaneal synchondrosis: An image articles

Elizabeth Swan

The sustentaculum bone is a hard prominence at the average surface of the calcaneus that verbalizes with the center calcaneal articular surface of the bone and offers a significant help for the average section of the foot. Its upper articular surface is inward, and its lower surface has a score for the ligament of the flexor hallucis longus. The sustentaculum bone offers connection to the plantar calcaneonavicular (spring) tendon on its foremost edge and the tibiocalcaneal tendon and the average talocalcaneal tendon (part of the deltoid tendon) on its average edge.
