2024年5月29日 · The bifurcate ligament, also known as the Chopart ligament 5,8, is a key stabilizer of the subtalar and midtarsal joints 5,7. It originates from the anterior process of the calcaneus before dividing into two bands that insert into the navicular and cuboid 5-7 .

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.

2023年3月19日 · Bifurcate Ligament Diagnosis. A clinical assessment can reveal slightly distal pain to the specific location of a lateral ankle sprain where there may be pain on palpation of the Anterior Process of the Calcaneus. An x-ray is the most common scan for an ankle sprain and an oblique x-ray can identify an Avulsion fracture of the Bifurcate Ligament.

The bifurcate ligament is a strong ligament that arises from the anterior part of the dorsal surface of the calcaneus. As its name suggests, the ligament bifurcates forming a Y-shaped ligament. One arm of the Y, referred to as the calcaneocuboid part, extends to the dorsal surface of the cuboid bone, while the other arm, the calcaneonavicular ...

The talonavicular joint is stabilized by the dorsal talonavicular ligament (D-TNL), the calcaneonavicular component of the bifurcate ligament (CN-BL), and the spring ligament complex consisting of the superomedial (SM-CNL), medioplantar oblique (MPO-CNL) and the inferoplantar longitudinal (IPL-CNL) calcaneonavicular ligaments.

Bifurcate Ligament : Performing the Test: To perform this test, the examiner should use the upper hand to stabilize the talus as well as to aid in applying varus stress to the foot while using the other hand to supinate the foot. Positive Test: Pain over the bifurcate ligament : Interpretation

2023年10月30日 · A bifurcate ligament injury is a condition that affects the ligaments within the foot, specifically the bifurcate ligament. These ligaments play a crucial role in stabilizing the midfoot and connecting various bones. Injury to these ligaments can lead to pain, instability, and impaired foot function.

2018年8月20日 · Morphological characteristics of the bifurcate ligament were determined by measuring fiber bundle length, width, and thickness at the center of each ligament. This classification resulted in 68 Type I feet (68%), 32 Type II feet (32%), and 0 Type III feet (0%).

The bifurcate ligament was classified into three types: presence of both calcaneonavicular ligament and calcaneocuboid ligament (Type I); absence of calcaneocuboid ligament (Type II); and absence of calcaneonavicular ligament (Type III).

The bifurcate ligament (BL), also known as the Chopart ligament, is a strong Y-shaped piece of tissue that helps stabilize the calcaneocuboid joint in the foot. The fact that the BL also serves to support the midtarsal and talocalcaneonavicular joints has led to frequent references to it as the “keystone” of the transverse tarsal joint.
