Distal Radioulnar Joint (Forearm Rotation) - distal being the end of these bones that is nearest the wrist.

Bones: Radius and ulnar.

Ligaments: There is a long mesh of ligaments that run between the radius and the ulnar and a small one that binds the two heads near the wrist.

Muscles: The pronator quadratus muscle assists in pronation of the hand hand (palm facing down).

Manipulation: The ring finger is oriented at the exact axis is movement (rotation of the forearm between the radius and ulnar) therefor by grabbing and bending the ring finger upwards you can "jam" the rotation of the forearm. Breaking the ring finger could cause minor discomfort of forearm rotation but there is little evidence for this.

Members: If you have broken your ring finger (this is not a common break) please add on how it felt to pronate and supanate the hand (rotate the arm so that the palm is facing down or up).
