What ligaments make up the bifurcate ligament?

The bifurcate ligament, also designated the “ligament of Chopart,” is formed by two ligaments: the medial calcaneocuboid ligament and lateral calcaneonavicular ligament [1, 2] (Fig. 1). Isolated injuries involving the calcaneocuboid joint are rare and frequently overlooked.

What is the bifurcate ligament?

The bifurcate ligament (BL) of the foot, also called Chopart ligament, is a strong Y-shaped structure that stabilizes the calcaneocuboid joint [1]. The BL also stabilizes the talocalcaneonavicular and midtarsal joints, and therefore, has been described as the keystone of the transverse tarsal joint [2].

What does the bifurcate ligament attach to?

The bifurcate ligament attaches the anterior process of the calcaneus to the navicular and cuboid bones. Excessive traction to this ligament can result in a fracture of the anterior process of the calcaneus.

What are the two parts of the bifurcate ligament?

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.

What ligament forms part of the articular surface of the talocalcaneonavicular joint?

Plantar calcaneonavicular ligament
Plantar calcaneonavicular ligament According to some authors, this ligament consists of two separate parts: a superomedial part and an inferior part. The dorsal surface of the superomedial part comprises the middle part of the articular cavity that articulates with the talar head.

Where is bifurcate ligament located?

calcaneus
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 movement does the plantar calcaneonavicular ligament prevent?

its medial border is blended with the forepart of the deltoid ligament of the ankle-joint. The plantar calcaneonavicular ligament, by supporting the head of the talus, is principally concerned in maintaining the arch of the foot.

What is Talocalcaneal ligament?

The lateral talocalcaneal ligament (LTCL) is a short yet sturdy bundle of muscle fibers found in the human ankle. The lateral talocalcaneal ligament stretches from the lateral (outer-side) portion of the talus, or ankle bone, to the lateral surface of the calcaneus, or heel bone.

What does the plantar calcaneonavicular ligament do?

It connects the navicular bone’s plantar (foot side) surface with the sustentaculum of the calcaneus, a shelf-like facet of the heel bone. It also provides support to the head of the talus, a bone that makes up the lower portion of the ankle joint. In doing so, the ligament bears a significant amount of body weight.

What does the plantar Calcaneonavicular do?

The plantar calcaneonavicular ligament helps to maintain the medial longitudinal arch of the foot and by providing support to the head of the talus bears the major portion of the body weight. It is the main part of the spring ligament complex.
