What is Tennis Elbow?
Tennis elbow is a common name for the elbow condition lateral epicondylitis. It is an overuse injury that causes inflammation and microtears of the tendons that attach to the lateral epicondyle.
Tennis elbow is a painful condition occurring from repeated muscle contractions at the forearm. The condition is more common in sports activities such as tennis, painting, hammering, typing, gardening and playing musical instruments.
Tennis elbow and golfer’s elbow are similar, except that golfer’s elbow occurs on the inside of the elbow and tennis elbow occurs on the outside of the elbow. Both conditions are a type of tendonitis - inflammation of the tendons.
Causes of Tennis Elbow
Tennis elbow is usually caused by overuse of the forearm muscles but may also be caused by direct trauma such as with a fall, car accident or work injury.
Tennis elbow is commonly seen in tennis players, hence the name, especially when poor technique is used while hitting the ball with a backhand stroke. Other common causes include any activity that requires repetitive motion of the forearm such as painting, hammering, typing, raking, weaving, gardening, lifting heavy objects and playing musical instruments.
Symptoms of Tennis Elbow
The signs and symptoms of tennis elbow can include the following:
- Elbow pain that gradually worsens
- Pain to the outside of the elbow that radiates to the forearm and wrist with grasping objects
- Weak grip
- Painful grip
- Pain that is exacerbated in the elbow when the wrist is bent back
Diagnosis of Tennis Elbow
Your doctor will evaluate tennis elbow by reviewing your medical history, performing a thorough physical examination and ordering X-rays, MRI or electromyogram (EMG) to detect any nerve compression.
Treatment of Tennis Elbow
Your doctor will first recommend conservative treatment options. These may include:
- Limit the use and rest the arm from activities that worsen symptoms.
- Splints or braces may be ordered to decrease stress on the injured tissues.
- Apply ice packs on the elbow to reduce swelling.
- Avoid activities that bring on the symptoms and increase stress on the tendons.
- Anti-inflammatory medications and/or steroid injections may be ordered to treat pain and swelling.
- Physical therapy may be ordered for strengthening and stretching exercises to the forearm once your symptoms have decreased.
- Pulsed ultrasound may be used to increase blood flow and promote healing to the injured tendons.
If conservative treatment options fail to resolve the condition and symptoms persist for 6 -12 months, your surgeon may recommend a surgical procedure called lateral epicondyle release surgery. Your surgeon will decide whether to perform your surgery in the traditional open manner (single large incision) or endoscopically (2 to 3 tiny incisions and the use of an endoscope – narrow lighted tube with a camera). Your surgeon will decide which option is best for you depending on your specific circumstances.
Your surgeon moves aside soft tissues to view the extensor tendon and its attachment on the lateral epicondyle and then trims or releases the tendon, and reattaches it to the bone. Any scar tissue present will be removed as well as any bone spurs. After the surgery is completed, the incision(s) are closed by suturing or by tape.
Following surgery, you are referred to physical therapy to improve the range of motion and strength of your joint.
