It is a major arm disorder which occurs commonly in adults between 30 and 50 years, with an estimated prevalence of 1% to 3% in the general population. Lateral epicondylitis results from the overuse of the extensor muscles, causing inflammation or irritation of the tendon insertion (4). It is common in workers whose job requires manual and repetitive work .
