The elbow is the intermediate joint of the upper limb. It involves three bones, the humerus proximally and the radius and the ulna distally. In the upper limb, this joint is the counterpart of the knee in that it controls the length of the limb; in combination with the joints above and below it, the elbow orientates and directs the hand.
