Do you experience pain on the outer side of your elbow that makes even handshakes difficult? If you feel sharp, shooting pain from your elbow to your forearm when lifting a cup or turning a door handle, you may have lateral epicondylitis.
What Exactly Is Lateral Epicondylitis
Lateral epicondylitis (tennis elbow) is a condition where the tendons attached to the lateral epicondyle—the bony prominence on the outer side of the elbow—become damaged. It primarily occurs when repetitive microscopic injuries accumulate in the tendon of the extensor carpi radialis brevis (the muscle that bends the wrist upward).
Due to its nickname "tennis elbow," many people mistakenly think it only affects athletes. In reality, it occurs widely among people who repeatedly extend their wrists or grip objects. Housewives, carpenters, chefs, and office workers can all develop this condition regardless of their profession.
The forearm muscles continuously pull at the area where they attach to the outer elbow bone, causing microscopic tears in the tendon. When these tears don't heal properly, they lead to chronic inflammation. As we age, tendons lose their elasticity and become more susceptible to injury.
Symptoms of Lateral Epicondylitis
The main characteristic of lateral epicondylitis is discomfort that extends from the outer side of the elbow down into the forearm (Pathan & Sharath, 2023). Importantly, it's not just elbow pain—the pain worsens with specific movements.
Location and Nature of Pain
The pain is most severe at a point 1-2 cm below the bony prominence on the outer side of the elbow. It feels sharp when pressed with a finger. The pain may also radiate along the outer forearm down to the wrist.
The area feels stiff in the morning but gradually loosens with movement. As afternoon arrives and usage increases, discomfort returns. Rest provides relief, but pain often returns shortly after resuming activities.
Movement-Related Pain
Pain worsens when extending the wrist upward or gripping objects with a clenched fist. Activities that require wrist force—such as lifting cups, cooking with a frying pan, shaking hands, or turning door handles—become problematic.
Repetitive wrist movements like typing or using a computer mouse also aggravate the condition. In severe cases, even daily activities like brushing teeth or combing hair become difficult.
Diagnosing Lateral Epicondylitis
Lateral epicondylitis is primarily diagnosed through medical history and physical examination. Imaging tests are used supplementarily to rule out other conditions or assess the extent of tendon damage.
Physical Examination
Several special tests are used in clinical settings to diagnose lateral epicondylitis (Zwerus et al., 2018). The Cozen test involves the patient making a fist and extending the wrist while the doctor provides resistance. If this causes discomfort on the outer side of the elbow, the test is positive.
Mill's test involves extending the elbow while the wrist is flexed downward. Pain and tension on the outer side of the elbow suggest lateral epicondylitis. The Thomsen test involves providing resistance while the patient extends the wrist with the arm stretched forward.
The middle finger extension test is also helpful. If the elbow hurts when resistance is applied to extending the middle finger, lateral epicondylitis is likely.
Imaging Studies
Plain radiographs (X-rays) check for bone abnormalities or calcification. In chronic lateral epicondylitis, small calcium deposits may be visible at the tendon attachment site. Most cases appear normal on X-rays.
Ultrasound examination can visualize tendon thickness, swelling, and tears in real-time. If the tendon appears thicker than normal or shows irregular internal structure, it supports the diagnosis. The advantage is that the exact painful area can be identified during the examination.
MRI shows the extent of tendon damage in the greatest detail. However, it doesn't always correlate with clinical symptoms. Symptoms may exist without MRI abnormalities, and conversely, MRI changes may be present without symptoms. MRI is mainly performed when considering surgery or when differentiation from other conditions is necessary.
Both physical examination and imaging studies have their advantages and limitations, making it important to combine medical history with multiple tests for diagnosis.
Why Conservative Treatment Takes Priority
Most cases of lateral epicondylitis improve with conservative treatment. Even though it takes time, recovery can be expected with appropriate care.
Basic Treatment
The most important step is avoiding movements that cause discomfort. Rather than complete rest, patients should remain active within pain-free ranges. During the acute phase, ice application for 15 minutes, 3-4 times daily, reduces inflammation and discomfort.
Nonsteroidal anti-inflammatory drugs (NSAIDs) help relieve pain and inflammation. If oral medications are burdensome, topical anti-inflammatory preparations can be used. Tennis elbow braces distribute the force on forearm muscles, reducing tendon stress. They should be worn about 5 cm below the elbow, taking care not to apply them too tightly.
In clinical practice, patients who receive aggressive early treatment are less likely to develop chronic conditions. Those who endure pain before seeking help tend to require longer treatment periods and experience more frequent recurrences.
Physical Therapy and Exercise
Physical therapy is crucial for pain relief and functional recovery (Landesa-Piñeiro & Leirós-Rodríguez, 2022). Treatments like ultrasound or electrical stimulation increase blood flow and promote healing.
Wrist extensor strengthening exercises are key. Using light weights (0.5-1 kg), slowly move the wrist up and down. Perform 3 sets daily, with 10 repetitions per set. Start within pain-free ranges and gradually increase intensity.
Eccentric contraction exercises are particularly effective. Use the healthy hand to lift the affected wrist, then slowly lower it using only the affected hand. This strengthens the tendon while minimizing stress.
Stretching is also important. Extend the arm forward and flex the wrist downward, then pull with the other hand to stretch the outer forearm. Hold for 30 seconds, repeat 3 times, and perform multiple times throughout the day.
Actual Effectiveness of Injection Therapy and Procedures
When conservative treatment doesn't provide improvement, injection therapy or other procedures may be considered. Each treatment method has advantages and disadvantages, requiring careful selection.
Steroid Injections
Steroid injections significantly reduce discomfort in the short term. Most patients show improvement within 2-4 weeks after injection. The problem is the high long-term recurrence rate.
Repeated steroid injections may actually weaken tendons. Therefore, they're best used for short periods when acute pain is severe.
In clinical practice, patients who don't combine exercise therapy after steroid injections often experience recurrence. Returning to strenuous activities immediately after pain reduction from injections often leads to re-aggravation.
New Treatment Methods
Extracorporeal shockwave therapy promotes tissue regeneration by stimulating angiogenesis (new blood vessel formation) (Bonczar et al., 2024). Focused shockwaves are used for deep tissue treatment, while radial shockwaves help with superficial muscle relaxation.
PRP (platelet-rich plasma) injection involves concentrating platelets rich in growth factors from the patient's own blood and injecting them. The disadvantage is high cost.
These treatments are not cure-alls. Without basic exercise therapy and lifestyle modifications, no injection can provide a complete solution.
When Is Surgery Considered
Most cases of lateral epicondylitis improve over time. Some don't respond to conservative treatment and require surgical consideration.
Surgery is considered when there's no improvement despite aggressive conservative treatment for 12 months or more. It's reserved for cases where daily life or occupational activities are seriously impaired. Surgical options include open surgery, arthroscopic surgery, and percutaneous surgery. Recently, arthroscopic surgery is preferred due to faster recovery.
Post-surgery recovery requires 3-6 months, during which consistent rehabilitation exercises are necessary. Even after surgery, excessive use should be avoided to prevent recurrence.
The prognosis is generally favorable. Appropriate treatment helps with daily life recovery. However, recurrence is common, so prevention measures are important even after symptom improvement. Improving work postures, taking adequate rest, and consistent stretching help prevent recurrence.
Prolonged discomfort can become chronic and difficult to treat. Early accurate diagnosis and appropriate treatment initiation are crucial.
Frequently Asked Questions
How do lateral epicondylitis and medial epicondylitis differ?
Lateral epicondylitis causes pain on the outer side of the elbow, while medial epicondylitis (golfer's elbow) affects the inner side. Lateral epicondylitis worsens when extending the wrist upward, while medial epicondylitis worsens when flexing the wrist downward.
How can lateral epicondylitis be prevented?
Take 10-minute breaks every hour during repetitive activities. When lifting heavy objects, keep palms facing upward to reduce forearm stress. Use wrist supports during computer work, and perform adequate stretching before and after exercise. For tennis or golf players, equipment checks and proper posture correction are essential.
Is exercise allowed with lateral epicondylitis?
Exercising within pain-free ranges is helpful. Avoid arm-intensive exercises and focus on lower body or light aerobic exercises. Once pain subsides somewhat, begin rehabilitation exercises but gradually increase intensity. Excessive exercise can delay recovery, so caution is needed.
What precautions should be taken after injection therapy?
Avoid lifting heavy objects or repetitive movements for 2-3 days after injection. Apply ice if heat or swelling occurs at the injection site. Returning to normal activities immediately after pain reduction can easily cause recurrence. Gradually increase activity levels. Injection effects usually begin to appear 1-2 weeks later.
How is chronic lateral epicondylitis treated?
Chronic lateral epicondylitis lasting 6 months or more requires a different approach than acute cases. Since degenerative changes rather than inflammation are the main problem, procedures that promote tissue regeneration are important. Eccentric exercises, extracorporeal shockwave therapy, and PRP injections may be considered. Lifestyle modifications and consistent rehabilitation exercises are essential.
