Overview
Tennis elbow, clinically known as lateral epicondylitis or lateral elbow tendinopathy, is a common condition characterised by pain and tenderness on the outer part of the elbow. It is classified as an enthesopathy, which is a disorder affecting the attachment point where tendons connect to the bone. Specifically, it involves the extensor carpi radialis brevis (ECRB) tendon, which is responsible for stabilising the wrist when the elbow is straight.
While the name suggests a connection to sports, the majority of individuals diagnosed with this condition do not play tennis. The condition primarily involves degenerative changes in the tendon rather than acute inflammation. It typically affects adults during middle age, with both males and females experiencing the condition with similar frequency.
Causes and Risk Factors
The primary cause of tennis elbow is the repetitive use and overuse of the forearm muscles. This constant stress leads to the development of microtears in the tendon fibres where they attach to the lateral epicondyle, the bony bump on the outside of the elbow. Over time, these small tears can lead to a disorganised arrangement of collagen and the formation of damaged tissue.
Several lifestyle and professional factors can increase the risk of developing this condition:
- Occupational Demands: Individuals in professions requiring frequent, forceful, or repetitive arm and wrist movements are at higher risk. Common examples include painters, carpenters, plumbers, cooks, and butchers.
- Hobbies and Sports: Engagement in racquet sports such as tennis, badminton, or squash can contribute to the condition, particularly if improper stroke techniques are used or if equipment is incorrectly sized.
- Age: The risk is generally higher for individuals who are over forty years old, as tendons may become less resilient with age.
- Medical Factors: Certain systemic conditions, such as diabetes mellitus, can negatively impact tissue healing and are associated with a higher risk of recurrence or more persistent symptoms.
Symptoms
The most prominent symptom of tennis elbow is pain and tenderness located directly over the outer bony prominence of the elbow. This pain often radiates down the back of the forearm and can vary in intensity from a mild ache to a severe, constant burning sensation that interferes with daily life.
Common signs and symptoms include:
- Pain when gripping or holding objects, such as a cup or a heavy bag.
- Discomfort when twisting the forearm, such as when turning a doorknob or opening a jar.
- Pain that worsens when fully extending the arm or bending the wrist upwards against resistance.
- A noticeable weakness in grip strength.
Red-Flag Symptoms While tennis elbow is usually a gradual-onset condition, certain symptoms may indicate a more serious underlying issue requiring urgent medical evaluation:
- Symptoms following a sudden trauma or fall, which could suggest a fracture.
- Significant bruising or swelling around the joint.
- Severe pain that occurs at night and wakes you from sleep.
- A burning or tingling sensation that may suggest a nerve-related problem rather than a tendon injury.
Diagnosis
A healthcare professional typically diagnoses tennis elbow through a comprehensive physical examination and a review of the patient’s medical history. During the assessment, the doctor will apply pressure to the lateral epicondyle to check for tenderness and may ask the patient to move their wrist and fingers against resistance to reproduce the pain.
A common clinical test used is Cozen’s test, where the patient’s ability to resist wrist extension is evaluated while the elbow is extended.
While imaging is not always necessary for a diagnosis, it may be used to rule out other potential causes of elbow pain, such as osteoarthritis or bone spurs.
- X-rays: Used primarily to evaluate the bone structure and identify any calcification in the tendon.
- Ultrasound or MRI: These may be recommended in chronic cases to assess the extent of tendon damage, such as the presence of large tears or structural changes.
Treatment Options
The management of tennis elbow is individualised based on the severity of the symptoms and how long they have persisted. Most cases respond well to conservative, non-surgical measures.
Self-Care and Activity Modification The initial phase of treatment often involves resting the arm and avoiding repetitive activities that aggravate the pain. Modifying how certain tasks are performed, such as lifting objects with the palm facing upwards, can help reduce the strain on the affected tendon.
Medication Doctors may recommend anti-inflammatory medicines, available in both oral and topical forms, to help manage pain and reduce local swelling.
Physiotherapy and Rehabilitation A structured physiotherapy programme is often essential for recovery. A therapist can teach specific stretching and strengthening exercises designed to improve the flexibility and resilience of the forearm muscles. These may include isometric and eccentric exercises, which involve controlled loading of the tendon to stimulate repair.
Injections When standard conservative treatments are insufficient, injection therapies may be considered:
- Corticosteroid Injections: These can provide short-term pain relief but are generally used with caution as their long-term benefits may be limited.
- Platelet-Rich Plasma (PRP) Therapy: This involves using the patient’s own blood components, specifically concentrated platelets and growth factors, to promote tissue repair at the site of the injury.
Advanced Non-Surgical Procedures
- Extracorporeal Shockwave Therapy (ESWT): This procedure uses shockwaves to stimulate healing in the problematic tendon tissue.
- Ultrasonic Tenotomy: A minimally invasive procedure that uses ultrasonic energy to remove damaged tendon tissue through a small needle.
Surgical Treatment Surgery is typically reserved for cases that remain symptomatic after an extended trial of conservative management. Surgical options include:
- Open Surgical Release: The surgeon makes an incision over the elbow to remove damaged portions of the tendon.
- Arthroscopic Surgery: A minimally invasive approach using small incisions and a camera (arthroscope) to debride the damaged tissue, potentially allowing for a quicker initial recovery.
Prevention and Lifestyle Management
Reducing the risk of recurrence and managing daily activities effectively is key to long-term elbow health.
- Ergonomics: Improving the setup of your workstation and using tools with a proper grip size can significantly reduce repetitive strain.
- Correct Technique: In sports, ensuring proper stroke technique and avoiding “hitting the ball with a flexed elbow” can prevent excessive forces on the tendon.
- Preparation: Engaging in adequate warm-up exercises and stretching before participating in strenuous or repetitive forearm activities is highly advisable.
- Pacing: Take frequent short breaks during repetitive tasks and avoid starting unaccustomed levels of intense activity without gradual preparation.
When to Seek Medical Attention
If symptoms persist or worsen, it is advisable to consult a qualified healthcare professional for a proper evaluation. You should seek medical advice if you experience:
- Persistent symptoms that do not improve with rest and simple analgesics.
- Worsening pain that impacts your ability to perform daily activities.
- Progressive weakness in your grip or difficulty lifting light objects.
- Numbness or a loss of sensation in the arm or hand.
- Symptoms that develop immediately following a significant injury or trauma.
