What makes up the bifurcate ligament?

The dorsal talonavicular (TN) and dorsal calcaneocuboid (DCC) (shown as two bands) ligaments span the talonavicular and calcaneocuboid joints, respectively, while the bifurcate ligament—composed of two bands (calcaneonavicular and calcaneocuboid)—traverses both joints simultaneously.

Where is the bifurcate ligament?

calcaneus
The bifurcate ligament is a strong band, attached behind to the deep hollow on the upper surface of the calcaneus and dividing in front in a Y-shaped manner into a calcaneocuboid and a calcaneonavicular part.

How do you test a bifurcate ligament?

DIAGNOSTIC EXAMS:

1. Initial medial oblique x ray should be taken with every severe ankle sprain to rule out avulsion fracture of the anterior calcaneal process, especially when symptomatic over this specific region of the foot.
2. An MRI can confirm the diagnosis of bifucate ligament tear.

What are the 3 types of ligaments?

There are three types of the articulation ligaments: capsular, extracapsular and intracapsular. They differ by their location within a joint.

What is bifurcate ligament?

The bifurcated ligament (internal calcaneocuboid, interosseous ligament or bifurcate ligament) is a strong band, attached behind to the deep hollow on the upper surface of the calcaneus and dividing in front in a Y-shaped manner into a calcaneocuboid and a calcaneonavicular part.

What are the intrinsic ligaments?

The intrinsic wrist ligaments are situated entirely within the carpus, between carpal bones. These ligaments may be divided into two major categories: interosseous, between the carpal bones; and intrinsic capsular, attaching to the carpal bones.

What are the two parts of the bifurcate ligament?

Gross anatomy It consists of two components, which form a Y-shape: the calcaneonavicular component (also known as the lateral calcaneonavicular component) extends medially and attaches to the dorsolateral part of the navicular.
