About De Quervain Syndrome
De Quervain syndrome, also known as stenosing tenosynovitis, happens when the tendon sheath (a thin, protective covering around certain tendons in the wrist), thickens and becomes tight. This puts pressure on two tendons that move the thumb: the abductor pollicis longus (APL) and the extensor pollicis brevis (EPB). The extra pressure causes irritation and swelling, which leads to pain and limited thumb movement.
Non-modifiable risk factors for De Quervain syndrome cannot be changed or controlled. These include:
- Gender: Women have a higher prevalence of De Quervain syndrome compared to men.
- Age: The condition is more common in middle-aged individuals.
- Anatomical factors: Some people are born with a narrower space in the wrist where the tendons pass through, called the first dorsal compartment. This can increase the risk of developing De Quervain syndrome.
Modifiable risk factors, factors that can be influenced or changed, for De Quervain syndrome are not well-established. There may be an increased risk of De Quervain syndrome during pregnancy and in people with chronic conditions that involve inflammation, such as rheumatoid arthritis and diabetes. It is also worth noting that certain activities or habits may contribute to the development or worsening of symptoms. These factors may include repetitive thumb or wrist movements, excessive gripping or pinching, and prolonged use of vibrating tools.
It is important to note that these risk factors are based on general observations and may not apply to every individual. If you suspect you have De Quervain syndrome or are experiencing symptoms, it is recommended to consult with a healthcare professional for an accurate diagnosis and appropriate management.
The most common early symptoms of De Quervain syndrome include:
- Pain and swelling along the back and base of the thumb
- Pain and swelling along the thumb-side of the wrist
- Difficulty moving the thumb (a feeling that the thumb is “stuck”)
- Pain when moving the wrist or making a fist with the hand
It's important to note that these symptoms can vary from person to person. If you experience any of these symptoms continuously or without relief from resting the hand or using over-the-counter anti-inflammatory drugs, it's best to consult with a healthcare professional for an accurate diagnosis and appropriate treatment.
To diagnose De Quervain syndrome, healthcare providers commonly perform the following examinations, tests, and procedures:
- Medical history: Gathering information about your medical history and any previous diagnoses can help in the diagnostic process.
- Physical exam: The healthcare provider will check for pain, swelling, or tenderness on the thumb side of the wrist. They may also perform a Finkelstein test, where you bend your thumb across your palm and the wrist is gently turned—if this causes sharp pain, it’s a sign of the condition.
- Lab tests: May be done to rule out other conditions, like rheumatoid arthritis or infection.
- Imaging tests: X-rays can help rule out bone problems like fractures or arthritis. MRI (magnetic resonance imaging) scans or ultrasounds may be used to look at the tendons and see how inflamed or thickened they are.
Remember, these are general procedures, and your healthcare provider will determine which ones are necessary based on your specific symptoms and medical history. It's important to consult with your healthcare provider for a proper diagnosis and treatment plan.
The goals of treatment for De Quervain Syndrome are to relieve pain, improve joint motion, and prevent recurrence. Here are the different types of treatments and how they work towards achieving these goals:
- Medication: Nonsteroidal anti-inflammatory drugs (NSAIDs) can help reduce pain and inflammation in the affected area. They work by blocking the production of certain chemicals in the body that cause pain and swelling. However, medication dosing may be affected by many factors, so it's important to consult with your healthcare professional.
- Therapies: Physical therapy can be beneficial for De Quervain Syndrome. It includes exercises to improve strength and flexibility in the affected hand and wrist. Occupational therapy focuses on adapting daily activities to reduce strain on the affected area.
- Therapeutic procedures: Corticosteroid injections may be recommended to reduce inflammation and relieve pain. These injections deliver medication directly into the tendon sheath, providing localized relief. However, it's important to note that potential side effects can occur, so consult with your healthcare professional.
- Health behavior changes: Making changes in your daily activities can help alleviate symptoms. Avoiding repetitive motions or activities that strain the thumb and wrist can reduce inflammation and prevent further damage.
- Other treatments: In cases where conservative treatments fail, surgical release of the tendon sheath may be necessary. This procedure aims to alleviate pressure on the tendons and restore normal function.
Remember, treatment plans should be tailored to individual needs, so it's essential to consult with a healthcare professional for personalized advice.
