Epicondylitis (Tennis Elbow): A Comprehensive Guide
Overview
Epicondylitis, commonly known as tennis elbow, is a painful condition that occurs when the tendons in your elbow are overworked, usually by repetitive motions of the wrist and arm. Despite its name, you don't have to play tennis to develop this condition—it can affect anyone who performs repetitive gripping activities, especially with the thumb and first two fingers.
Who it affects: While tennis elbow can occur at any age, it is most common in adults between the ages of 30 and 50. It affects 1-3% of the general population and up to 50% of tennis players during their careers (NIH). Both men and women are equally affected.
Prevalence: Tennis elbow is one of the most common causes of elbow pain and is responsible for a significant number of work-related musculoskeletal disorders. It is estimated that 40% of people will experience tennis elbow at some point in their lives (Mayo Clinic).
Symptoms
The symptoms of tennis elbow develop gradually and can range from mild to severe. Common signs and symptoms include:
- Pain or burning on the outer part of your elbow that may radiate down your forearm.
- Weak grip strength, making it difficult to hold items like a coffee cup, turn a doorknob, or shake hands.
- Pain when lifting or bending your arm, such as when lifting weights, swinging a tennis racket, or even picking up a gallon of milk.
- Stiffness in the elbow, especially in the morning or after periods of inactivity.
- Pain when making a fist or gripping objects tightly, such as a pen or tool.
- Tenderness when touching the bony bump on the outside of your elbow (lateral epicondyle).
Symptoms often worsen over time if the activity causing the condition is continued. Pain may also spread to your wrist, even at rest.
Causes and Risk Factors
Tennis elbow is caused by overuse and muscle strain. Repetitive motions and stress to the tissue lead to a series of tiny tears in the tendons that attach the forearm muscles to the bony prominence on the outside of your elbow.
While the exact cause isn't always clear, the condition is often linked to:
- Repetitive motions: Activities that involve repeated wrist extension (bending the wrist backward) and gripping, such as:
- Playing tennis (especially with poor technique or improper equipment).
- Using tools like screwdrivers, pliers, or scissors.
- Painting or using a paintbrush for extended periods.
- Typing or using a computer mouse excessively.
- Cooking, particularly chopping or stirring.
- Occupational factors: Jobs that require repetitive arm movements, such as plumbing, carpentry, or butchery, increase the risk.
- Age: Most common in adults between 30 and 50 years old.
- Poor technique or equipment: Using improper form during activities or equipment that is too heavy or incorrectly sized (e.g., a tennis racket with a grip that is too small).
- Sudden increase in activity: A sudden increase in the intensity or duration of an activity can strain the tendons.
Risk factors include:
- Being in an occupation that requires repetitive arm motions.
- Participating in certain sports, such as tennis, racquetball, or weightlifting.
- Smoking, which can impair tendon healing and increase the risk of developing tennis elbow.
- Obesity, which may increase strain on the tendons.
Diagnosis
Diagnosing tennis elbow typically involves a physical examination and a review of your medical history. Your doctor may ask about your occupation, hobbies, and any recent injuries or activities that could have contributed to your symptoms.
Common diagnostic methods include:
- Physical exam: Your doctor will apply pressure to the affected area and ask you to move your elbow, wrist, and fingers in various ways to assess pain and stiffness. Tests may include:
- Cozen's test: You'll be asked to extend your wrist against resistance while your doctor palpates the lateral epicondyle. Pain indicates tennis elbow.
- Mills test: Your doctor will passively flex your wrist while extending your elbow. Pain suggests tennis elbow.
- Grip strength test: Weakness in grip strength may be measured using a dynamometer.
- Imaging tests: While often unnecessary, your doctor may recommend:
- X-rays: To rule out other causes of elbow pain, such as arthritis or a fracture.
- MRI or ultrasound: To assess the extent of tendon damage or rule out other conditions like a herniated disk in the neck, which can cause similar symptoms.
In most cases, imaging tests are not needed to diagnose tennis elbow, as the condition can usually be identified through a physical exam alone.
Treatment Options
Tennis elbow often improves with self-care measures and nonsurgical treatments. Treatment focuses on relieving pain and promoting healing. Options include:
Self-Care and Lifestyle Changes
- Rest: Avoid activities that aggravate your elbow pain. Give your tendons time to heal by taking a break from repetitive motions.
- Ice therapy: Apply ice packs to your elbow for 15-20 minutes several times a day to reduce pain and inflammation.
- Over-the-counter (OTC) pain relievers: Medications like ibuprofen (Advil, Motrin) or naproxen (Aleve) can help reduce pain and swelling.
- Bracing or strapping: Using a counterforce brace or strap around your forearm can help reduce strain on the tendons.
- Ergonomic adjustments: Modify your workspace or tools to reduce strain. For example, use a larger-grip pen or an ergonomic mouse.
Physical Therapy
A physical therapist can teach you exercises to stretch and strengthen your forearm muscles, improving flexibility and reducing pain. Common techniques include:
- Eccentric exercises: Slow, controlled lengthening of the muscle to promote tendon healing.
- Ultrasound therapy: Uses sound waves to promote blood flow and healing.
- Massage or manual therapy: To improve circulation and reduce tension in the muscles.
Medications
- Topical creams: NSAID creams (e.g., diclofenac gel) can be applied directly to the skin to reduce pain and inflammation.
- Corticosteroid injections: Injections of corticosteroids (e.g., cortisone) can provide short-term pain relief, though they are not recommended for long-term use due to potential side effects like tendon weakening.
- Platelet-rich plasma (PRP) therapy: Involves injecting a concentration of your own platelets into the affected area to promote healing. Evidence for its effectiveness is mixed, but some studies suggest it may help (NIH).
Procedures and Surgery
If conservative treatments fail after 6-12 months, your doctor may recommend:
- Extracorporeal shock wave therapy (ESWT): Uses shock waves to stimulate healing in the tendon. Results are mixed, but it may be an option for chronic cases.
- Surgery: Rarely needed, but options include:
- Open surgery: The damaged tendon is repaired through an incision.
- Arthroscopic surgery: A minimally invasive procedure using small instruments and a camera.
Living with Epicondylitis (Tennis Elbow)
Managing tennis elbow in your daily life involves a combination of rest, activity modification, and gradual rehabilitation. Here are some tips to help you cope:
- Avoid aggravating activities: Temporarily stop or modify activities that cause pain. For example, switch to a different stroke in tennis or use ergonomic tools at work.
- Use proper technique: Whether in sports or daily tasks, ensure you're using the correct form to minimize strain. Consider working with a coach or physical therapist.
- Apply heat or ice: Use ice for acute pain and swelling, and heat for stiffness or chronic discomfort.
- Gradual return to activity: Once pain subsides, slowly reintroduce activities, starting with low intensity and short durations.
- Strengthen and stretch: Regularly perform exercises recommended by your physical therapist to maintain flexibility and strength in your forearm muscles.
- Use supportive devices: Wearing a brace or using tape (e.g., kinesiology tape) can provide additional support during activities.
- Manage stress: Stress can increase muscle tension. Practices like yoga, meditation, or deep breathing may help.
Most people with tennis elbow recover fully within 6 months to 2 years, though some may experience recurring symptoms if they return to aggravating activities too soon.
Prevention
Preventing tennis elbow involves reducing strain on your tendons and using proper techniques during activities. Here are some strategies:
- Warm up and stretch: Before engaging in physical activity, warm up your muscles with light exercises and stretch your forearm muscles.
- Use proper equipment: Ensure your sports equipment (e.g., tennis racket) is the right size and weight for you. Consider using a racket with a larger grip or a softer string tension.
- Strengthen your muscles: Regularly perform exercises to strengthen your forearm, wrist, and shoulder muscles. Focus on both flexors and extensors.
- Take breaks: Avoid prolonged repetitive motions. Take frequent breaks during activities that strain your elbow.
- Improve your technique: Work with a coach or trainer to ensure you're using proper form in sports or work-related tasks.
- Use ergonomic tools: At work, use tools designed to reduce strain, such as ergonomic keyboards, mice, or padded handles.
- Listen to your body: If you feel pain or discomfort, stop the activity and rest. Pushing through pain can lead to further injury.
Complications
If left untreated, tennis elbow can lead to chronic pain and long-term dysfunction. Potential complications include:
- Chronic pain: Persistent pain that interferes with daily activities, work, or hobbies.
- Reduced range of motion: Stiffness and limited movement in the elbow and wrist.
- Weakness: Permanent weakness in the forearm and grip strength, making it difficult to perform tasks like lifting or gripping.
- Tendon rupture: In severe cases, the tendon may tear completely, requiring surgical repair.
- Secondary conditions: Compensating for elbow pain can lead to strain or injury in other parts of the arm, shoulder, or neck.
Early intervention and proper treatment can help prevent these complications and promote faster recovery.
When to Seek Emergency Care
- Sudden, severe pain in your elbow, especially after an injury or trauma.
- Inability to move your elbow or wrist at all.
- Signs of infection, such as fever, redness, warmth, or swelling around the elbow.
- Numbness or tingling in your arm, hand, or fingers, which could indicate nerve involvement.
- Elbow deformity or a visible lump or gap in the tendon, which may suggest a rupture.
These symptoms may indicate a more serious condition, such as a fracture, dislocation, or tendon rupture, which requires urgent medical evaluation.
If your symptoms do not improve with self-care measures within a few weeks, or if pain interferes with your daily activities, consult a healthcare professional for further evaluation and treatment.
