What is an Olecranon Fracture?

The elbow joint is a joint of the upper limbs, formed between the arm bone (humerus) and the forearm bones (radius and ulna). The olecranon (upper end) of the ulna articulates with the humerus, allowing bending motions of the upper limbs at the elbow. The radial head (upper end of radius) articulates with the humerus
