Information on the hand, wrist and elbow

The elbow in the human body is made up of three bones that join together to form a hinge joint. The upper arm bone or humerus connects from the shoulder to the elbow forming the top of the hinge joint. The lower arm or forearm consists of two bones, the radius and the ulna. These bones connect the wrist to the elbow forming the bottom portion of the hinge joint.

The three joints of the elbow include:

  • Ulnohumeral joint is where movement between the ulna and humerus occurs.
  • Radiohumeral joint is where movement between the radius and humerus occurs.
  • Proximal radioulnar joint is where movement between the radius and ulna occurs.
