The ligament is strong and well defined, yet its flexibility permits the slightly oval head of the radius to rotate freely during pronation and supination. [ 4 ] [ 5 ] The head of the radius is wider than the bone's neck, and, because the annular ligament embraces both, the radial head is "trapped" inside the ligament which thus acts to prevent ...
The head of the radius has a cylindrical form, and on its upper surface is a shallow cup or fovea for articulation with the capitulum of the humerus. The circumference of the head is smooth; it is broad medially where it articulates with the radial notch of the ulna , narrow in the rest of its extent, which is embraced by the annular ligament .
It occurs between the circumference of the head of the radius and the ring formed by the radial notch of the ulna and the annular ligament. [2] The interosseous membrane of the forearm and the annular ligament stabilise the joint. [2] A number of nerves run close to the proximal radioulnar joint, including: median nerve; musculocutaneous nerve ...
Annular ligament may refer to: Annular ligament of femur; Annular ligaments of fingers; Annular ligament of radius; Annular ligament of stapes (also known as the ...
The lateral meniscus is grooved laterally for the tendon of the popliteus, which separates it from the fibular collateral ligament.. Its anterior end is attached in front of the intercondyloid eminence of the tibia, lateral to, and behind, the anterior cruciate ligament, with which it blends; the posterior end is attached behind the intercondyloid eminence of the tibia and in front of the ...
The annular ligament secures the head of the radius from dislocation, which would otherwise tend to occur, from the shallowness of the cup-like surface on the head of the radius. Without this ligament, the tendon of the biceps brachii would be liable to pull the head of the radius out of the joint. The head of the radius is not in complete ...
The lateral collateral ligament (LCL, long external lateral ligament or fibular collateral ligament) is an extrinsic ligament of the knee located on the lateral side of the knee. [ 1 ] [ verification needed ] [ 2 ] Its superior attachment is at the lateral epicondyle of the femur (superoposterior to the popliteal groove); its inferior ...
The composition of the triangular ligamentous structure on the lateral side of the elbow varies widely between individuals [1] and can be considered either a single ligament, [2] in which case multiple distal attachments are generally mentioned and the annular ligament is described separately, or as several separate ligaments, [1] in which case parts of those ligaments are often described as ...
