Summary about Disease
Extensor tendonitis (also known as extensor tenosynovitis) is an inflammation of the tendons that extend the wrist and fingers. These tendons run along the back of the hand and forearm. Overuse, repetitive motions, and direct trauma are common causes. It results in pain and difficulty moving the affected hand and wrist.
Symptoms
Pain on the back of the hand and/or wrist, especially during or after activity.
Tenderness to the touch along the affected tendons.
Swelling and/or redness in the affected area.
A grating sensation (crepitus) when moving the wrist or fingers.
Stiffness and limited range of motion in the wrist and fingers.
Weakness in grip strength.
Causes
Repetitive motions: Activities involving repeated wrist and finger movements (e.g., typing, writing, knitting, playing musical instruments).
Overuse: Excessive use of the hand and wrist.
Direct trauma: Injury to the back of the hand or wrist.
Underlying conditions: Rheumatoid arthritis or other inflammatory conditions can increase the risk.
Poor ergonomics: Incorrect posture or workspace setup.
Medicine Used
Pain relievers: Over-the-counter pain relievers like ibuprofen (Advil, Motrin) or naproxen (Aleve) can help reduce pain and inflammation. Acetaminophen (Tylenol) can help with pain but doesn't reduce inflammation.
Topical NSAIDs: Creams or gels containing nonsteroidal anti-inflammatory drugs (NSAIDs) may be applied directly to the affected area.
Corticosteroid injections: In some cases, a doctor may inject corticosteroids into the tendon sheath to reduce inflammation.
Prescription Pain Medication: In severe cases, stronger pain medication may be prescribed.
Is Communicable
No, extensor tendonitis is not communicable. It is not caused by an infectious agent and cannot be spread from person to person.
Precautions
Avoid repetitive motions: Take frequent breaks during activities involving repetitive hand and wrist movements.
Proper ergonomics: Ensure a proper workstation setup to minimize strain on the wrist and hand.
Strengthening exercises: Perform regular stretching and strengthening exercises to support the wrist and hand.
Use proper technique: Learn and use proper techniques for activities that put stress on the wrist and hand.
Use supportive devices: Wear a wrist splint or brace to provide support and limit movement.
How long does an outbreak last?
The duration of extensor tendonitis can vary depending on the severity of the condition and how quickly treatment is initiated. With appropriate rest, treatment, and modification of activities, symptoms may improve within a few weeks to a few months. Chronic cases may persist longer if the underlying cause is not addressed or if the condition is severe.
How is it diagnosed?
Physical Examination: A doctor will examine the hand and wrist, checking for tenderness, swelling, and range of motion.
Medical History: The doctor will ask about the patient's symptoms, activities, and any previous injuries or medical conditions.
Provocative Tests: Specific tests may be performed to reproduce the symptoms and assess the function of the extensor tendons.
Imaging (Rare): X-rays may be taken to rule out other conditions, such as fractures. In some cases, MRI may be used to evaluate the tendons in more detail.
Timeline of Symptoms
The timeline of symptoms can vary:
Initial Stage: Gradual onset of pain and tenderness on the back of the hand or wrist.
Progression: Pain worsens with activity and may become constant. Swelling and stiffness may develop.
Chronic Stage: Persistent pain and limited range of motion. Symptoms may flare up with activity.
Important Considerations
Early diagnosis and treatment are important to prevent the condition from becoming chronic.
It's crucial to identify and address the underlying cause of the tendonitis (e.g., overuse, poor ergonomics).
Compliance with treatment recommendations (e.g., rest, activity modification, exercises) is essential for successful recovery.
If symptoms do not improve with conservative treatment, further evaluation and intervention may be necessary.
Consult a healthcare professional for proper diagnosis and treatment.
