Key take-home points:
- Tennis elbow (lateral epicondylitis) and golfer’s elbow (medial epicondylitis) are overload tendon injuries.
- They typically occur after minor trauma to the proximal insertions of the extensor or flexor forearm muscles.
- Up to 3% of the population can be affected with a peak incidence in middle age. Men and women are equally affected.
- Tennis elbow is about 6 to 7 times more common than golfer’s elbow; however, tennis is not the cause in most cases.
- The mechanism of injury is typically micro-tears caused by repetitive overuse of the extensor carpi radialis brevis and the common extensor tendon, such as repetitive lifting, heavy tool use and unaccustomed activity involving the elbow and forearm.
- Symptoms of tennis elbow typically occur gradually and usually (but not always) affect the dominant arm. Elbow movements are normal.
- Clinical tests include Tinel’s sign, Mills’ test and Cozen’s test.
- Further investigations are not usually required unless the diagnosis is unclear.
- The management of both types of epicondylitis is similar; this includes rest and activity restriction, the use of heat or ice, use of orthosis and analgesia.
- Steroid injections should not be offered routinely.
- Refer to secondary care if there is no response to treatment after 6 months, or if there is severe pain or impairment of arm function.
