Lateral (meaning away from the midline of the body) epicondylalgia (meaning pain of the epicondyle) is a painful condition on the outer aspect of the elbow. The common name for lateral epicondylalgia is tennis elbow but only 5% of the people afflicted with this condition play tennis.
Pain at the elbow may have one or more causes: it could be from the forearm tendons that attach at the outer aspect of the elbow, it could be referred pain from the next, it could be from one or more of the joints at the elbow, or it may originate from the radial nerve that is in close proximity to the elbow joint.
It often occurs with repetitive use of the arm especially with a clenched fist. Most cases are not due to tennis.
Local tenderness and pain with resisted and passive extension of the wrists is common.
Activity modification, anti-inflammatory medications, ice, and progressive stretching and strengthening will relieve most cases. Surgery is only an option in recalcitrant cases.
