The dorsal talonavicular ligament is a broad, thin band, which connects the neck of the talus to the dorsal surface of the navicular bone; it is covered by the Extensor tendons. The plantar calcaneonavicular supplies the place of a plantar ligament for this joint.
An avulsion fracture is a bone fracture which occurs when a fragment of bone tears away from the main mass of bone as a result of physical trauma. This can occur at the ligament by the application of forces external to the body (such as a fall or pull) or at the tendon by a muscular contraction that is stronger than the forces holding the bone ...
The dorsal talonavicular ligament extends from the dorsal aspect of the foot from the neck of the talus to the navicular. [ 1 ] [ 2 ] The socket of this joint is formed by the concave articular facets of the navicular, calcaneus, calcaneonavicular part of bifurcate ligament and the spring ligament (plantar calcaneonavicular ligament), where the ...
There are five ligaments connecting the calcaneus and the cuboid bone, forming parts of the articular capsule: the dorsal calcaneocuboid ligament. [2] part of the bifurcated ligament. [2] the long plantar ligament. [2] and the plantar calcaneocuboid ligament. [2]
The calcaneonavicular ligament (ligamentum calcaneonaviculare) is attached to the lateral side of the navicular. (Note this is NOT the spring ligament which is commonly called the plantar calcaneonavicular ligament). It is commonly injured in "sprain-type" inversion injuries producing an avulsion fracture at the anterolateral process of the ...
The dorsal or superomedial component of the ligament presents a fibrocartilaginous facet, lined by the synovial membrane, upon which a portion of the head of the talus rests. Its plantar surface, consisting of the intermedial and lateral ligaments, is supported by the tendon of the tibialis posterior ; its medial border is blended with the ...
In medicine, an avulsion is an injury in which a body structure is torn off by either trauma or surgery (from the Latin avellere, meaning "to tear off"). [1] The term most commonly refers to a surface trauma where all layers of the skin have been torn away, exposing the underlying structures (i.e., subcutaneous tissue , muscle , tendons , or ...
The dorsal cuneonavicular ligaments consist of fibrous bands that join the dorsal surface of the navicular bone to the dorsal surfaces of the three cuneiform bones. v t
