De Quervain's tenosynovitis
What is De Quervain's tenosynovitis?
De Quervain's tenosynovitis is irritation and thickening around the tendons on the thumb side of the wrist, within the first dorsal compartment. It is often aggravated by repetitive lifting, gripping, twisting or caring for young children.
Common symptoms
Patients describe sharp radial wrist pain, pain lifting objects with the thumb up, tenderness near the radial styloid, swelling and difficulty with gripping, opening jars or lifting a baby.
Diagnosis and imaging
Diagnosis is clinical, based on local tenderness and provocative tests such as Finkelstein or Eichhoff manoeuvres. Ultrasound may show tendon sheath thickening or separate tendon compartments when symptoms persist.
Non-surgical treatment
Treatment includes thumb spica splinting, activity modification, hand therapy, anti-inflammatory measures and corticosteroid injection. Accurate injection into the involved compartment is important.
Surgical treatment
Surgery is considered when symptoms persist despite splinting and injection. Release of the first dorsal compartment creates more space for tendon gliding while protecting superficial sensory nerves.
Recovery and follow-up
After surgery, the wrist and thumb move early as the wound heals. Tenderness and swelling settle gradually, with grip and lifting increased as comfort returns.
De Quervain's tenosynovitis FAQs
Why does De Quervain's hurt when lifting a baby or kettle?
These tasks load the thumb tendons while the wrist is angled, increasing friction in the tight tendon compartment.
How is de quervain's tenosynovitis diagnosed?
Diagnosis starts with a focused history and examination, then uses imaging selectively to confirm the pattern of injury, exclude related problems and plan treatment accurately.
Will a splint cure it?
A splint can reduce tendon irritation and may settle early cases, especially when combined with load modification or injection.
Will I need surgery for de quervain's tenosynovitis?
Many patients improve without surgery. Surgery is considered when symptoms remain limiting despite appropriate non-surgical care, when there is significant structural damage, or when delay may compromise function.
When can I return to lifting and normal hand use?
Return depends on the diagnosis, treatment type, tissue healing and the physical demands of the activity. The plan is usually staged, with strength, range of motion and confidence rebuilt before unrestricted loading.
