Olecranon fracture

Olecranon fracture is a fracture of the bony portion of the elbow. The injury is fairly common and often occurs following a fall or direct trauma to the elbow. The olecranon is the proximal extremity of the ulna which is articulated with the humerus bone and constitutes a part of the elbow articulation. Its subcutaneous location makes it vulnerable to direct trauma. Powerful pull of the triceps muscle can also cause avulsion fractures.
