Tennis Elbow (Lateral Epicondylitis)
Tennis elbow, or lateral epicondylitis, is a painful condition of the elbow caused by overuse. Not surprisingly, playing tennis or other racquet sports can cause this condition. But several other sports and activities can also put you at risk.
Tennis elbow is an inflammation of the tendons that join the forearm muscles on the outside of the elbow. The forearm muscles and tendons become damaged from overuse — repeating the same motions again and again. This leads to pain and tenderness on the outside of the elbow.
There are many treatment options for tennis elbow. In most cases, treatment involves a team approach. Primary doctors, physical therapists, and, in some cases, surgeons work together to provide the most effective care.
Your elbow joint is a joint made up of three bones: your upper arm bone (humerus) and the two bones in your forearm (radius and ulna). There are bony bumps at the bottom of the humerus called epicondyles. The bony bump on the outside (lateral side) of the elbow is called the late
Muscles, ligaments, and tendons hold the elbow joint together.
Lateral epicondylitis, or tennis elbow, involves the muscles and tendons of your forearm. Your forearm muscles extend your wrist and fingers. Your forearm tendons -- often called extensors -- attach the muscles to bone. They attach on the lateral epicondyle. The tendon usually involved in tennis elbow is called the Extensor Carpi Radialis Brevis (ECRB).
Recent studies show that tennis elbow is often due to damage to a specific forearm muscle. The extensor carpi radialis brevis (ECRB) muscle helps stabilize the wrist when the elbow is straight. This occurs during a tennis groundstroke, for example. When the ECRB is weakened from overuse, microscopic tears form in the tendon where it attaches to the lateral epicondyle. This leads to inflammation and pain.
The ECRB may also be at increased risk for damage because of its position. As the elbow bends and straightens, the muscle rubs against bony bumps. This can cause gradual wear and tear of the muscle over time.
Athletes are not the only people who get tennis elbow. Many people with tennis elbow participate in work or recreational activities that require repetitive and vigorous use of the forearm muscle.
Painters, plumbers, and carpenters are particularly prone to developing tennis elbow. Studies have shown that auto workers, cooks, and even butchers get tennis elbow more often than the rest of the population. It is thought that the repetition and weight lifting required in these occupations leads to injury.
Most people who get tennis elbow are between the ages of 30 and 50, although anyone can get tennis elbow if they have the risk factors. In racquet sports like tennis, improper stroke technique and improper equipment may be risk factors.
Lateral epicondylitis can occur without any recognized repetitive injury. This occurence is called "insidious" or of an unknown cause.

The symptoms of tennis elbow develop gradually. In most cases, the pain begins as mild and slowly worsens over weeks and months. There is usually no specific injury associated with the start of symptoms.
Common signs and symptoms of tennis elbow include:
Pain or burning on the outer part of your elbow
Weak grip strength
The symptoms are often worsened with forearm activity, such as holding a racquet, turning a wrench, or shaking hands. Your dominant arm is most often affected; however both arms can be affected.
Site of the pain and pathology in Tennis elbow.
Approximately 80% to 95% of patients have success with nonsurgical treatment.
Rest. The first step toward recovery is to give your arm proper rest. This means that you will have to stop participation in sports or heavy work activities for several weeks.
Non-steroidal anti-inflammatory medicines. Drugs like aspirin or ibuprofen reduce pain and swelling.
Wrist stretching exercise with elbow extended.
Equipment check. If you participate in a racquet sport, your doctor may encourage you to have your equipment checked for proper fit.
Physical therapy. Specific exercises are helpful for strengthening the muscles of the forearm. Your therapist may also perform ultrasound, ice massage, or muscle-stimulating techniques to improve muscle healing.
Brace. Using a brace centered over the back of your forearm may also help relieve symptoms of tennis elbow. This can reduce symptoms by resting the muscles and tendons.
Steroid injections. Steroids, such as cortisone, are very effective anti-inflammatory medicines. Your doctor may decide to inject your damaged muscle with a steroid to relieve your symptoms.
Extracorporeal shock wave therapy. Shock wave therapy sends sound waves to the elbow. These sound waves create "microtrauma" that promote the body's natural healing processes. Shock wave therapy is considered experimental by many doctors, but some sources show it can be effective.
If your symptoms do not respond after 6 to 12 months of nonsurgical treatments, your doctor may recommend surgery.
Most surgical procedures for tennis elbow involve removing diseased muscle and reattaching healthy muscle back to bone.
The right surgical approach for you will depend on a range of factors. These include the scope of your injury, your general health, and your personal needs. Talk with your doctor about the options. Discuss the results your doctor has had, and any risks associated with each procedure.
Open surgery. The most common approach to tennis elbow repair is open surgery. This involves making an incision over the elbow.
Open surgery is usually performed as an outpatient surgery. It rarely requires an overnight stay at the hospital.
Arthroscopic surgery. Tennis elbow can also be repaired using tiny instruments and small incisions. Like open surgery, this is a same-day or outpatient procedure.
