Lateral epicondylitis or lateral epicondylalgia, also known as tennis elbow, shooter's elbow, and archer's elbow, is a condition where the outer part of the elbow becomes sore and tender. It is commonly associated with playing tennis and other racquet sports, though the injury can happen to almost anyone.
Tennis elbow is an overuse injury occurring in the lateral side of the elbow region, but more specifically it occurs at the common extensor tendon that originates from the lateral epicondyle. While the common name "tennis elbow" suggests that people who play tennis may develop this condition, other activities of daily living may also cause it.
Data was collected from 113 patients who had tennis elbow, and the main factor common to them all was overexertion. Sportspersons as well as those who used the same repetitive motion for many years, especially in their profession, suffered from tennis elbow. It was also common in individuals who performed motions they were unaccustomed to. The data also mentioned that the majority of patients suffered tennis elbow in their right arms.
Other descriptions for tennis elbow are lateral epicondylosis, lateral epicondylalgia, or simply lateral elbow pain.
Lateral epicondylitis is a painful condition at the lateral epicondyle of the humerus. The acute pain that a person might feel occurs as one fully extends the arm. Since the pathogenesis of this condition is still unknown, an appropriate name is still in the works. Despite the term "tennis elbow," tennis players make up a small number of individuals who suffer from this ailment, which is often found in manual workers such as builders and waiters. Bowden states that it should be called lateral elbow syndrome.
Runge is usually credited for the first description in 1873 of the condition. The term tennis elbow was first used in 1883 by Major in his paper "Lawn-tennis elbow".
