Calcaneonavicular Ligament
(Redirected from Spring Ligament)
Description
Other Names
- Calcaneonavicular Ligament
- Spring ligament complex
- Calcaneonavicular Ligament complex
- Spring ligament fibrocartilage complex
- Plantar calcaneonavicular ligament
General
- Broad thick band of ligaments that supports of the hind- and midfoot
- Connects the calcaneus, navicular to support the talus
- Term 'spring ligament' is a misnomer, there are no elastic or spring-like properties
- Functions like a normal ligament
Gross Anatomy
- Superomedial ligament
- Forms a sling, suspending/articulating against the head of the talus
- Origin from anterior sustentaculum tali with a wide insertion onto the navicular
- Merges with the inferior aspect of the tibiospring ligament (a portion of the superficial deltoid ligament)
- Strongest and most important longitudinal arch stabilizer; also most commonly torn/repaired
- Medioplantar oblique ligament
- Also called lateral calcaneonavicular ligament
- Inferoplantar longitudinal ligament
- Also called intermedial calcaneonavicular ligament
- Minor role in stabilizing hindfoot, longitudinal arch
Function
- Acts as a static restraint to the arch[3]
- In conjunction with the plantar fascia, tibionavicular ligament, long and short plantar ligaments, and the talocalcaneal ligament
- Acts as a sling for the talar head (acetabulum pedis)[4]
- Preventing the talar head from plantarflexing
- Prevents subluxation of the talonavicular joint
- Incompetence or injury of the spring ligament
- May allow subluxation of the talonavicular joint
- The talar head sags into plantarflexion with associated abduction through the transverse tarsal joint
- Eversion of the calcaneus leading to hindfoot valgus
