Bifurcate Ligament
(Redirected from Plantar calcaneonavicular ligament)
Description
Other Names
- Bifurcate Ligament[2]
- Chopart Ligament
Introduction
- Key stabilizer of the Talonavicular Joint, Calcaneocuboid Joint
- Thus a major contributor to Chopart Joint stability
Gross Anatomy
- Lies deep to extensor hallucis brevis, extensor digitorum brevis
- Arises from the anterior process of calcaneus
- Short stem with two bands inserts on the navicular, cuboid
Calcaneonavicular ligament (medial band)
- Origin: deep to the interosseous talocalcaneal ligament, cervical ligament, extensor digitorum brevis muscle on the calcaneus,
- Extends anteromedially, attaches to the dorsolateral navicular
- Forms the medial component
- Longer and thicker measuring 20-25 mm (length) and 10 mm (width) 5,6
- Almost always (~99%) present[3]
Calcaneocuboid ligament (lateral band)
- Extends anteriorly and attaches to the dorsomedial cuboid
- Forms the lateral component[4]
- Measures 10 x 5 mm
- Absent in ~25% (range 10-40%)
