Lateral epicondylitis is a painful condition affecting the area where the extensor tendons attach to the bone on the outside of the elbow. Degeneration or tearing of the tendon origin occurs, causing localized pain that increases with activities, including lifting and gripping. This condition may be caused by overuse or trauma. Conservative treatment is often beneficial, including activity modification, splints/orthotics, exercise and injection. Surgery may be appropriate in cases that do not respond to conservative measures.
