olecranon

The olecranon is the prominent bony point of your elbow, located at the back of the joint. It is the part of the ulna bone that sticks out when you straighten your arm. The olecranon serves as an attachment site for muscles and ligaments that help move and stabilize the elbow. It also acts as a lever for extending the forearm, making it essential for activities like pushing or reaching. Injuries to the olecranon, such as fractures, are common from falls or direct impacts and often require medical evaluation for appropriate treatment.
