Overview
Tennis elbow is inflammation, soreness, or pain on the outside (lateral) side of the upper arm near the elbow.

There may be a partial tear of the tendon fibers, which connect muscle to bone. The tear may be at or near where these fibers begin, on the outside of the elbow.

What are the symptoms of Tennis elbow?

 * Elbow pain that gradually worsens
 * Pain radiating from the outside of the elbow to the forearm and back of the hand when grasping or twisting
 * Weak grasp

What causes Tennis elbow?
The part of the muscle that attaches to a bone is called a tendon. Muscles in your forearm attach to the bone on the outside of your elbow.

When you use these muscles over and over again, small tears develop in the tendon. Over time, this leads to irritation and pain where the tendon is attached to the bone.

Who is at highest risk?
This injury is common in people who play a lot of tennis or other racquet sports, hence the name "tennis elbow." Backhand is the most common stroke to cause symptoms.

However, any activity that involves repetitive twisting of the wrist (like using a screwdriver) can lead to this condition. Therefore, painters, plumbers, construction workers, cooks, and butchers are all more likely to develop tennis elbow.

This condition may also be due to constant computer keyboard and mouse use.

Diagnosis
The diagnosis is made based on signs and symptoms, because x-rays are usually normal. Often there will be pain or tenderness when the tendon is gently pressed near where it attaches to the upper arm bone, over the outside of the elbow.

There is also pain near the elbow when the wrist is extended (bent backwards, like revving a motorcycle engine) against resistance.

X-rays are rarely needed.

When to seek urgent medical care?
Apply home treatment (over-the-counter anti-inflammatory medications and keeping the elbow still) if:


 * Symptoms are mild
 * You have had this disorder before and you are sure you have tennis elbow

Call for an appointment with your health care provider if:


 * This is the first time you have had these symptoms
 * Home treatment does not relieve the symptoms

Treatment options
The first step is to rest your arm and avoid the activity that causes your symptoms for at least 2 - 3 weeks. You may also want to:


 * Put ice on the outside of your elbow 2 - 3 times a day.
 * Take nonsteroidal anti-inflammatory medications (such as ibuprofen, naproxen, or aspirin).

If your tennis elbow is due to sports activity, you may want to:


 * Ask about any changes you can make in your technique.
 * Check any sports equipment you're using to see if any changes may help.
 * Think about how often you have been playing and whether you should cut back.

If your symptoms are related to working on the comptuer, ask your boss about making changes.

An occupational therapist can show you exercises to stretch and strengthen the muscles of your forearm.

You can buy a special brace for tennis elbow at most drug stores. It wraps around the first part of your forearm and takes some of the pressure off the muscles.

Your doctor may also inject cortisone and a numbing medicine around the area where the tendon attaches to the bone. This may help decrease the swelling and pain.

If the pain continues after 6 - 12 months of rest and treatment, surgery may be recommended. Talk with your orthopedic surgeon about the risks, and whether surgery might help.

What to expect (Outlook/Prognosis)?
Most people improve with nonsurgical treatment. The majority of those who do have surgery show an improvement in symptoms.

Possible complications

 * Failure to improve with nonsurgical or surgical treatment. This may be due to nerve entrapment in the forearm
 * Recurrence of the injury with overuse
 * Rupture of the tendon with repeated steroid injections

Prevention of Tennis elbow
To help prevent tennis elbow:


 * Apply an ice pack to the outside of the elbow
 * Maintain good strength and flexibility in the arm muscles and avoid repetitive motions
 * Rest the elbow when bending and straightening are painful
