Lateral epicondyle

Lateral Epicondyle is a part of the human anatomy specifically located in the humerus bone of the upper arm. It is a bony prominence found on the outside of the elbow, where several muscles of the forearm originate.

Anatomy

The lateral epicondyle is a small, tuberculated eminence, curved a little forward, and giving attachment to the radial collateral ligament of the elbow joint. The capitulum of the humerus is placed on its front and lower part. It gives attachment to the anconeus behind, and to the supinator and extensor muscles of the forearm.

Clinical Significance

The lateral epicondyle is the point of origin for the extensor muscles of the forearm. These muscles are responsible for the extension of the wrist and fingers. Inflammation of the area, often due to overuse, can lead to a condition known as lateral epicondylitis, also known as "tennis elbow".
