Lateral Humeral Epicondylitis, commonly known as tennis elbow, is a condition that causes pain and inflammation on the outer side of the elbow joint. It is a form of tendinitis or tendinopathy that specifically affects the tendons attached to the lateral epicondyle of the humerus bone in the upper arm.
This condition typically occurs as a result of repetitive arm and wrist movements, particularly those involving the extensor muscles of the forearm. Activities such as playing tennis, painting, carpentry, typing, and other repetitive motions can lead to micro-tears in the tendons, causing inflammation and pain in the lateral side of the elbow.
Symptoms of lateral humeral epicondylitis include pain or tenderness on the outer side of the elbow, weakness in grip strength, difficulty in fully extending the arm, and discomfort during activities that involve gripping or lifting objects. In severe cases, the pain may radiate down the forearm.
Treatment for lateral humeral epicondylitis usually begins with conservative measures such as rest, icing the affected area, and the use of nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce pain and inflammation. Physical therapy exercises to strengthen the forearm muscles, applying braces or splints to relieve stress on the tendons, and corticosteroid injections may be recommended in more persistent cases.
With proper rest and treatment, most individuals recover from lateral humeral epicondylitis within six months to a year. However, it is important to avoid repetitive movements that may exacerbate symptoms and to gradually return to activities to prevent re-injury.
