Annular Ligament of Radius Anatomical Relations
The annular ligament attaches to the anterior margin of the radial notch of the ulna. This attachment forms a loop or a ring that holds the head of the radius against the ulna; this arrangement allows the head of the radius to rotate within the ligament (i.e., during pronation and supination).

Annular Ligament of Radius Structure
The annular ligament of the radius is a strong band that wraps around the head of the radius. Its deep surface is lined with cartilage, where it is in contact with the radial head (Standring, 2016).
Annular Ligament of Radius Function
The annular ligament of the radius is the principal stabilizer of the proximal radioulnar joint.
