The olecranon is a bony prominence located at the upper end of the ulna, one of the two long bones in the forearm. It forms the point of the elbow and serves as an attachment site for muscles and ligaments. The olecranon plays a crucial role in the movement of the elbow joint, allowing for bending and straightening of the arm. In addition to its structural importance, the olecranon is also involved in various activities, such as lifting and throwing. Injuries to the olecranon, such as fractures or bursitis, can lead to pain and limited mobility in the elbow, affecting daily activities and overall function.
