Plantar calcaneonavicular ligament
|Plantar calcaneonavicular ligament|
Ligaments of the medial aspect of the foot. (Plantar calcaneonavicular ligament labeled at bottom center.)
Ligaments of the sole of the foot, with the tendons of the Peronæus longus, Tibialis posterior and Tibialis anterior muscles. (Plantar calcaneonavicular ligament labeled at right, second from the bottom.)
|Latin||ligamentum calcaneonaviculare plantare|
This ligament not only serves to connect the calcaneus and navicular, but supports the head of the talus, forming part of the articular cavity in which it is received.
The dorsal surface of the ligament presents a fibrocartilaginous facet, lined by the synovial membrane, and upon this a portion of the head of the talus rests.
The plantar calcaneonavicular ligament helps to maintain the medial longitudinal arch of the foot, and by providing support to the head of the talus, bears the major portion of the body weight.
