De Quervain’s Tenosynovitis: Understanding the Thumb-Side Wrist Pain
If you’ve been experiencing sharp pain on the thumb side of your wrist— especially while lifting your child, using your phone, or twisting your wrist—you might be dealing with De Quervain’s Tenosynovitis. This is a common condition that affects the tendons responsible for thumb movement.
The condition involves inflammation of two key tendons:
- Abductor Pollicis Longus (APL)
- Extensor Pollicis Brevis (EPB)
These tendons pass through a tight fibro-osseous tunnel near the wrist. When they become irritated or inflamed, the tunnel narrows, leading to pain during thumb and wrist movements.
What Causes It?
De Quervain’s Tenosynovitis typically results from repetitive strain, such as:
- Lifting babies or heavy objects
- Excessive texting or smartphone use
- Repetitive wrist twisting during cooking, cleaning, or gym exercises
- Increased hand use in new mothers after childbirth
- Higher incidence in women and individuals with inflammatory conditions
Common Symptoms
Patients with De Quervain’s Tenosynovitis often report:
- Pain on the radial (thumb) side of the wrist
- Pain that worsens with gripping or lifting
- Swelling or tenderness over the first dorsal compartment
- Difficulty holding objects
- A painful stretching sensation while moving the thumb
The Finkelstein test—where the thumb is bent into the palm and the wrist is deviated towards the little finger—typically produces sharp pain and helps confirm the diagnosis.
Diagnosis
Diagnosis of De Quervain’s Tenosynovitis is usually clinical and based on symptoms and physical examination. Imaging studies are rarely required unless:
- Symptoms appear atypical
- There is suspicion of ganglion or arthritis
- Conservative treatment fails to provide relief
Ultrasound imaging, if performed, may reveal thickened tendons or septation between the APL and EPB tendons.
Treatment Options
Most patients experience significant improvement with structured, non-surgical treatment, including:
- Rest and activity modification to avoid heavy lifting and repetitive thumb movements
- Thumb spica splint to immobilize the thumb and wrist
- Anti-inflammatory medications (NSAIDs) to reduce pain and swelling
- Physiotherapy including tendon gliding, stretching, ultrasound therapy, and strengthening exercises
- Corticosteroid injections with a high success rate when administered early
- Surgery for chronic or resistant cases to release the tendon sheath
Prognosis
With appropriate and timely treatment, most patients recover fully within weeks to months. Delayed treatment can prolong symptoms, making early recognition and intervention essential for optimal recovery.
