Diseases

Physicians diagnose tennis elbow based on the history of outer elbow pain and tenderness often with recent repetitive-use injury. Tenderness at the outer elbow with normal range of motion of the elbow joint assures the diagnosis. Generally, no radiology testing is necessary. MRI scanning can illustrate inflammation of the outer elbow.

Avoiding strain injury of the elbow joint can prevent tennis elbow. Tennis players can benefit by proper instruction in hitting techniques. Tennis elbow straps can be used to minimize the risk of injury to the elbow tendons. Exercises that strengthen the involved muscles can be helpful to avoid a reoccurrence once symptoms have disappeared.

Symptoms of tennis elbow include dull pain and tenderness at the outer elbow. There can be elbow stiffness and a sensation of weakness. Typically with tennis elbow, people retain the full range of motion of the elbow and there is no significant swelling or discoloration. Holding a beverage cup or shaking hands can bring on the pain.

Risks of tennis elbow include any activity that can strain the elbow joint. Such activities include tennis, falling onto the extended upper extremity, using a screwdriver when unaccustomed, casting a fishing net, etc.

A strain injury to the tendon at the outer portion of the elbow causes tennis elbow. While this can occur by straining during a backhand tennis shot, it can also occur from many repetitive activities that can strain the elbow. These activities include using a screwdriver or work that includes similar motions, Frisbee disc throwing, and lifting objects by extending the wrist, etc.

Tennis elbow is inflammation of the tendon at the outer portion of the elbow, leading to pain. Classically, tennis elbow is a strain injury to this tendon from hitting a backhand shot at tennis. The medical term for tennis elbow is lateral epicondylitis because it involves inflammation at the insertion point of the tendon at the outer portion of the humerus bone at the elbow joint (the epicondyle). Most people with lateral epicondylitis actually acquire it from activities other than playing tennis.In contrast, when the tendon that attaches at the inner portion of the elbow is inflamed, the condition is referred to as medial epicondylitis (or "golfer's elbow" because golfers commonly injure this area after striking the ground to take a deep divot).

Tennis elbow most often has a complete recovery with conservative measures, particularly by resting the joint and avoiding reinjury.

Resting the elbow and employing measures to reduce the local inflammation are effective treatments for tennis elbow. Cold application several times daily and anti-inflammatory medications (such as ibuprofen [Advil] or naproxen [Aleve]) can be helpful. Physical therapy and rehabilitation exercises for the elbow that are guided by therapists can be helpful for persisting pain and inflammation. For tennis elbow that is resistant to these measures, local cortisone injection can be beneficial. Rarely, surgical repair of the injured tendon is considered.
