Tennis elbow, or “lateral epicondylitis”, is condition causing pain along the outside of the elbow. The muscles that extend the wrist and open the fingers insert into a portion of the bone on the outside of the elbow called the “lateral epicondyle”. Small tears of the muscle at its insertion site (the tendon) is a common cause of pain in the area that is experienced when lifting or grasping objects.
Common causes include overuse, or trauma to the forearm muscles, especially the extensor carpi radialis brevis, an important muscle for extending the wrist (such as when hitting a backhand in tennis). Tennis elbow is frequently seen in individuals between 30 and 60 years of age, and has been referred to as a “rite of passage of middle age”.
Tennis elbow can be diagnosed by talking with your doctor and having them examine your elbow. There is often pain when pushing on the “lateral epicondyle”, and when resisting wrist or finger extension.
- Activity modification – avoid aggravating activities, and focus on lifting objects with your palms facing up, which puts less tension on your extensor muscles
- Anti-inflammatories (such as ibuprofen or naproxen – if medically safe)
- Bracing - counterforce strap
- Steroid injection into site of pain and inflammation
- Therapy to stretch the forearm muscles
- Surgery is rarely required, as the condition tends to improve with time
- If over 6 months have passed, one may consider surgically repairing the torn muscle/tendon back to the bone
