Di Muzio, B., Rasuli, B. Lateral epicondylitis. Reference article, Radiopaedia.org. (accessed on 06 Oct 2021) https://radiopaedia.org/articles/13229. Lateral epicondylitis, also known as tennis elbow , is an overuse syndrome of the common extensor tendon and predominantly affects the extensor carpi radialis brevis (ECRB) tendon.
Lateral epicondylosis (also referred to as lateral epicondylitis or tennis elbow) is the most common cause of elbow pain and is frequently seen in athletes who throw, most commonly adults over 35 years of age (59,60).

While lateral epicondylitis is overwhelmingly encountered in the workplace, it is popularly associated with tennis and is thus often referred to as “tennis elbow”. 1. Lateral epicondylitis is a degenerative condition, which affects the extensor tendons of the hand and wrist at their origin.
Medial epicondylitis, although commonly termed golfer’s elbow, may occur in throwing athletes, tennis players, and bowlers, as well as in workers whose occupations (eg, carpentry) result in similar repetitive motions ( 7, 9 ). Lateral epicondylitis occurs with a frequency seven to 10 times that of medial epicondylitis ( 4, 9 ). Both lateral and medial epicondylitis most commonly occur in the 4th and 5th decades of life, without predilection with regard to sex.
Lateral epicondylitis is also known as the tennis elbow, although in 95% of cases it is seen in non-tennis players. It is due of chronic stress to the common extensor tendon, which results in partial tearing and tendinosis. Typically, the extensor carpi radialis brevis is the component that is involved.
