Superomedial calcaneonavicular ligament
Updates to Article Attributes
The superomedial calcaneonavicular ligament is a stabilizer of the longitudinal arch of the foot and one of three components of the spring ligament complex 1,2.
Gross anatomy
Thesuperomedial calcaneonavicular ligament connects the sustentaculum tali with the superomedial part of the navicular bone. Its superficial surface contains a fibrocartilaginous gliding zone faced towards the head of the talus and runs deep to the posterior tibialtibialis tendon 1,2. It serves as the distal insertion point for the tibiospring ligament.
Attachments
The proximal insertion of the superomedial calcaneonavicular ligament is located at the anterior surface of the sustentaculum tali.
The superomedial calcaneonavicular ligament insertsat the superomedial part of the talar articular surface of the navicular bone bypassing the navicular tubercle 1.
Radiographic features
Ultrasound
The superomedial calcaneonavicular ligament can be visualized on ultrasound with the transducer placed parallel to the plantar surface just inferior to the medial malleolus with foot externally rotated in dorsal extension. The ligament is then visualized as a hyperechoic fibrillary structure running deep to the posterior tibialtibialis tendon 42.
MRI
On MRI the superomedial calcaneonavicular ligament is can be seen on coronal, axial and oblique axial images. The fibrocartilaginous gliding zone shows higher signal than the rest of the ligament and lies directly deep to the adjacent posterior tibialtibialis tendon and covers the talar head 53.
Related pathology
The superomedial ligament is the part most likely to be injured of the three components of the spring ligament complex.
