Anatomical terminology |
The plantar calcaneonavicular ligament (also known as the spring ligament or spring ligament complex) is a complex of three ligaments on the underside of the foot that connect the
Structure
The plantar calcaneonavicular ligamentous complex is a broad and thick band with three constituent ligaments. These connect the anterior margin of the
Its individual components are the:- superomedial calcaneonavicular ligament.[2]
- medioplantar oblique ligament.[2]
- inferior calcaneonavicular ligament.[2]
These ligament components attach to different parts of the navicular bone.[2]
The dorsal or superomedial component of the ligament presents a fibrocartilaginous facet, lined by the synovial membrane, upon which a portion of the head of the talus rests. Its plantar surface, consisting of the intermedial and lateral ligaments, is supported by the tendon of the
Function
This ligamentous complex not only serves to connect the
By providing support to the head of the talus, it bears most of the body weight in a normally functioning foot.Clinical significance
A sprain to the plantar calcaneonavicular ligament can result in flatfoot deformity, which can impair mobility.
