Key points

  • The ulna is the long bone on the little-finger side of the forearm in anatomical position.
  • Its upper end forms the point of the elbow and articulates with the humerus and radius.
  • Its shaft provides attachment sites for muscles and the interosseous membrane linking the forearm bones.
  • The radius rotates around the ulna during palm-up and palm-down movements, while an articular disc separates the ulna from the wrist bones.
