Spring ligament complex

Last revised by Dr Henry Knipe on 16 Sep 2022

The spring (plantar calcaneonavicular) ligament complex is a group of ligaments that connect the calcaneum and navicular and support the talus.

The spring ligament complex has three components: 

These ligaments act as the primary static stabilizers of the medial arch of the foot and, together with the posterior tibialis tendon (primary dynamic stabilizer), help support normal hindfoot relations.

Failure of these stabilizers leads to hindfoot valgus and pes planus / pes planovalgus 2.
