Tendinitis de Quervain, also known as De Quervain tenosynovitis, is a common condition that affects the tendons on the thumb side of your wrist. It occurs when the tendons around the base of the thumb become irritated or constricted, leading to pain and tenderness. This condition is often associated with repetitive activities, such as texting, gaming, or using hand tools. Understanding the causes and effective treatments for tendinitis de Quervain is essential for managing symptoms and preventing long-term damage.
The condition is named after the Swiss surgeon Fritz de Quervain, who first described it in the early 20th century. Tendinitis de Quervain is a type of tendosynovitis, which is inflammation of the tendons and their surrounding synovial fluid. The condition typically affects the tendons of the extensor pollicis brevis and abductor pollicis longus muscles, which control thumb movement.
Causes of Tendinitis de Quervain
The causes of tendinitis de Quervain can be divided into two main categories: intrinsic and extrinsic factors. Intrinsic factors include individual characteristics, such as age, sex, and medical history. Extrinsic factors, on the other hand, are related to external factors, such as repetitive activities, poor posture, and equipment use.
Repetitive activities, such as gripping, twisting, or bending, can cause micro-trauma to the tendons, leading to inflammation and irritation. This is often seen in individuals who perform repetitive tasks, such as assembly line workers, musicians, or athletes. Poor posture, such as holding the wrist in an awkward position, can also contribute to the development of tendinitis de Quervain.
Risk Factors for Tendinitis de Quervain
Several risk factors have been identified for tendinitis de Quervain, including:
| Risk Factor | Description |
|---|---|
| Repetitive activities | Performing repetitive tasks, such as gripping, twisting, or bending |
| Poor posture | Maintaining awkward wrist or hand positions |
| Age | Middle-aged individuals are more prone to developing tendinitis de Quervain |
| Female sex | Women are more likely to develop tendinitis de Quervain than men |
| Medical history | History of rheumatoid arthritis, diabetes, or thyroid disorders |
Symptoms of Tendinitis de Quervain
The symptoms of tendinitis de Quervain typically include:
- Pain and tenderness on the thumb side of the wrist
- Swelling and redness around the affected area
- Crepitus or grinding sensation when moving the thumb
- Weakness or stiffness in the thumb or wrist
Diagnosis of Tendinitis de Quervain
The diagnosis of tendinitis de Quervain is typically made based on a combination of clinical evaluation and imaging studies. A healthcare professional will perform a physical examination to assess pain, tenderness, and range of motion. Imaging studies, such as X-rays or ultrasound, may be ordered to rule out other conditions, such as fractures or osteoarthritis.
The Finkelstein test is a commonly used diagnostic tool for tendinitis de Quervain. The test involves making a fist with the thumb inside and then bending the wrist toward the little finger. If pain is reproduced on the thumb side of the wrist, the test is considered positive.
Treatment Options for Tendinitis de Quervain
The treatment of tendinitis de Quervain typically involves a combination of conservative and interventional approaches.
Conservative Treatments
Conservative treatments include:
- Rest and ice: Avoiding activities that exacerbate symptoms and applying ice to reduce pain and inflammation
- Stretching and exercises: Gentle stretching and strengthening exercises to improve range of motion and reduce stiffness
- Physical therapy: Modalities, such as ultrasound or electrical stimulation, to promote healing and reduce pain
- Medications: Over-the-counter pain relievers, such as ibuprofen or acetaminophen, to manage pain and inflammation
Interventional Treatments
Interventional treatments include:
- Corticosteroid injections: Injecting corticosteroids into the tendon sheath to reduce inflammation and relieve pain
- Surgery: Release of the tendon sheath to relieve pressure and promote healing
