The annular ligament (orbicular ligament) is a strong band of fibers that encircles the head of the radius, and retains it in contact with the radial notch of the ulna. [ 1 ] Per Terminologia Anatomica 1998 , the spelling is "anular", [ 2 ] but the spelling "annular" is frequently encountered.

The foot may is a complex structure with 26 bones, 33 joints, numerous muscles, nerves and different ligament types. Any part of the foot can be affected by diseases, with symptoms ranging from mild aches to more serious pain hindering one's ability to walk or bear weight. Most minor cases of foot pain can be responded to by home care treatments.
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 stapediovestibular joint) Annular ligaments of trachea; Annular ligaments of toes
In radial head subluxation, there is little complaint of pain, and the person generally reports pain in the proximal forearm. The mechanism is slippage of the head of the radius under the annular ligament. The distal attachment of the annular ligament covering the radial head is weaker in children than in adults, allowing it to be more easily torn.
These ligaments arise from the distal radius medial border and insert on the ulna at two separate and distinct sites: the ulna styloid and the fovea (a groove that separates the ulnar styloid from the ulnar head). Each ligament consists of a superficial component and a deep component. The superficial components insert directly onto the ulna ...
Femur-fibula-ulna syndrome (FFU syndrome) is a very rare syndrome characterized by abnormalities of the femur (thigh bone), fibula (calf bone) and the ulna (forearm bone). ). There have been suggestions that FFU complex may be the same as proximal femoral focal deficiency (PFFD) although authors are currently in disagreement over whether or not the disorders are in fact sepa
