The Elbow Joint and Its Artificial Replacement

The elbow joint [1] is a special hinge joint in the middle of the arm. The three bones that form the elbow joint are the humerus of the upper arm and the radius and ulna of the forearm [1]. The bony prominence at the very tip of the elbow is the olecranon process of the ulna, and the inner aspect of the elbow is called the antecubital fossa.
