What to Know About a Radial Head

The Radial Head

The radial head is the proximal end of the radius, one of the two bones of the forearm. The radial head is involved in forming the elbow joint with the humerus, the bone of the upper arm, and with the ulna, the other bone of the forearm.

Anatomy of the Radial Head

The radial head is a round or oval-shaped structure that forms the apex of the elbow joint. It has two surfaces: a superior surface that articulates with the humerus, and an inferior surface that articulates with the ulna. The radial head is also connected to several ligaments and muscles that help to stabilize the elbow joint and allow it to move properly.

Function of the Radial Head

The radial head is responsible for several important functions in the elbow joint. It helps to:

- Stabilize the elbow joint

- Allow the forearm to rotate

- Prevent dislocation of the elbow

Radial Head Fractures

The radial head is one of the most commonly fractured bones in the elbow. Fractures of the radial head can be caused by a variety of injuries, such as falls, sports accidents, and car accidents. Symptoms of a radial head fracture can include pain, swelling, bruising, and difficulty moving the elbow.

Treatment for a radial head fracture may involve immobilization, physical therapy, and surgery. The type of treatment will depend on the severity of the fracture.

Radial Head Replacement

In some cases, a radial head fracture may require surgical treatment involving radial head replacement. Radial head replacement is a surgical procedure in which the damaged radial head is removed and replaced with an artificial implant. This procedure can help to restore stability and function to the elbow joint.

Recovery from Radial Head Fractures and Replacement

Recovery from a radial head fracture or replacement typically takes several months. Physical therapy is often recommended to help strengthen the muscles around the elbow joint and restore movement.

If you have experienced an injury to your elbow, it is important to see a doctor to be evaluated for a possible radial head fracture or other injury. Early diagnosis and treatment can help to ensure the best possible outcome.
