Elbow, Wrist & Hand

What It Is

When you bend your elbow, it's easy to feel the tip of it. This bony point is called the olecranon, and it is part of the ulna, one of the two bones of the forearm. It sits just under the skin with only a thin layer of tissue covering it, so it has little protection (American Academy of Orthopaedic Surgeons, n.d.). A direct blow to the bone or a fall onto the elbow can cause it to break (American Academy of Orthopaedic Surgeons, n.d.; Sherwood Forest Hospitals NHS Foundation Trust, 2023).

Elbow (Olecranon) Fracture Anatomy

Three bones join together to form the elbow joint. The bone in the upper arm is called the humerus. Two bones from the forearm, the radius and the ulna, make up the lower part of the joint (American Academy of Orthopaedic Surgeons, n.d.). All of the bones have a distinct shape. Ligaments, tendons and muscles help hold everything in proper alignment.

The elbow is mainly a hinge joint. The olecranon cups the lower end of the humerus to create the hinge, which lets the elbow bend and straighten, known as flexion and extension. The elbow is also important for rotation of the forearm, which allows the palm to turn up and down, known as supination and pronation (American Academy of Orthopaedic Surgeons, n.d.).

Elbow fractures are very painful. Olecranon fractures are most often caused by falling directly onto the elbow, a direct blow from something hard, or falling onto an outstretched arm, when the triceps muscle can pull a piece of bone off the olecranon (American Academy of Orthopaedic Surgeons, n.d.). The bone may crack slightly or break into many pieces (American Academy of Orthopaedic Surgeons, n.d.). Many olecranon fractures need surgery (American Academy of Orthopaedic Surgeons, n.d.).

Signs of a fracture include sudden, intense pain, not being able to move the elbow, swelling and bruising around the elbow, tenderness, numbness in one or more fingers, and a feeling that the elbow is going to pop out (American Academy of Orthopaedic Surgeons, n.d.).
