De Quervain’s Tenosynovitis
De Quervain’s Tenosynovitis is inflammation of the tendons that straighten and move the thumb (abductor pollicis longus and extensor pollicis brevis) where they pass through a tight sheath at the wrist. It causes pain on the thumb side of the wrist, especially with gripping, lifting a child, or twisting jars and keys.
At The New Foscote Hospital, you can access rapid consultant orthopaedic or hand surgeon assessment, targeted imaging, and a full range of non-surgical and surgical treatments to relieve pain and restore function.
Symptoms
- Pain and tenderness along the thumb-side (radial) wrist
- Pain with pinch, grip, lifting or twisting movements
- Swelling or a firm “thickened” area over the tendon sheath
- Finkelstein’s test (tucking the thumb and ulnar-deviating the wrist) provokes pain
- Occasionally catching or crepitus with tendon movement
Seek specialist advice if pain persists beyond a few weeks or interferes with work, sport or caring duties.
Causes And Risk Factors
- Repetitive or forceful thumb/wrist use (lifting infants, manual work, racket/club sports)
- Sudden increase in activity or new parenting tasks
- Previous wrist injury or arthritis at the base of the thumb
- More common in women and during the post-partum period
Diagnosis At The New Foscote Hospital
Diagnosis is primarily clinical. Your consultant may arrange:
- Ultrasound to assess tendon sheath thickening and guide injections
- X-ray if base-of-thumb (CMC) arthritis is suspected
- MRI in atypical or persistent cases

Treatment Options
Non-Surgical Care (first-line)
- Activity modification and ergonomic advice
- Thumb spica splint to rest the tendons
- Topical or oral anti-inflammatories (if appropriate)
- Targeted hand therapy: tendon-gliding, soft-tissue work, graded loading
Corticosteroid Injection
- Ultrasound-guided steroid injection into the tendon sheath can give rapid pain relief in many patients. A second injection may be considered if symptoms recur.
Surgical Treatment (for persistent or recurrent symptoms)
- De Quervain’s release (day-case): opening the tight sheath to allow the tendons to glide freely; sub-sheaths are protected to prevent tendon subluxation.
- Local anaesthetic ± sedation; a small incision at the radial wrist; early hand therapy follows.
Your surgeon will explain expected outcomes, risks (including scar tenderness, nerve irritation, or tendon subluxation), and recovery timelines.
Recovery And Rehabilitation
- Most people return to light activities within 1–2 weeks after surgery; full strength often returns over 4–6 weeks, guided by your surgeon and therapist.
- Hand therapy focuses on range of motion, scar care, progressive strengthening and a graded return to work/sport or childcare tasks.
When To Seek Specialist Help
Book a consultation if you have:
- Persistent thumb-side wrist pain despite rest and splinting
- Pain that wakes you or limits daily tasks and childcare
- Recurring symptoms after an initial improvement
- Concerns about returning safely to sport or manual work
Early assessment speeds recovery and reduces the risk of chronic pain.
