De Quervain's Tenosynovitis

Upper Limb

Overview

De Quervain's tenosynovitis is an inflammatory condition affecting the first dorsal compartment of the wrist, involving the abductor pollicis longus (APL) and extensor pollicis brevis (EPB) tendons. It presents with pain and swelling over the radial styloid process, typically triggered by repetitive thumb and wrist movements. The condition is common in new mothers, manual workers, and individuals with excessive gripping or pinching activities.

Pathophysiology

Repetitive thumb abduction and wrist extension load the APL and EPB tendons within the first dorsal compartment; the sheath thickens through myxoid degeneration rather than true inflammation. The thickened sheath narrows the compartment, restricting tendon gliding and perpetuating pain.

Patient Education

Avoid repetitive pinching and gripping activities; relative rest combined with gentle movement encourages healing without causing tendon atrophy.

Typical Presentation

Site

Radial-sided wrist pain over the styloid process, extending into the thumb base and lower forearm; pain is localized to the first dorsal compartment

Quality

Aching, burning, or sharp pain with activity; may include clicking or catching sensation with thumb movement

Intensity

Mild to moderate pain (3-7/10); increases with aggravating activities and may progress to constant ache if untreated

Aggravating

Repetitive thumb abduction and flexion; gripping or pinching; radial wrist deviation; activities requiring combined wrist and thumb movement; cold exposure

Relieving

Rest and immobilization; ice application; anti-inflammatory measures; thumb splinting in neutral position; avoiding triggering activities

Associated

Swelling and erythema over radial styloid; positive Finkelstein test; reduced grip strength; functional limitation in thumb opposition and pinching; possible crepitus on palpation

Orthopaedic Tests

Test descriptions are written with AI assistance from standard clinical texts. Where a test lists Sources, its description has been checked against them; those sources are independent and do not endorse OsteoKit. Accuracy figures and grades (A–D) appear only when checked against the published study; tests without one are marked “No accuracy study”.

Further reading: full test procedures are described in standard clinical examination texts, e.g. Magee & Manske, Orthopedic Physical Assessment (7th ed.), and Cook & Hegedus, Orthopedic Physical Examination Tests: An Evidence-Based Approach (2nd ed.).

Finkelstein's Test

Procedure

Forearm in neutral rotation, wrist in neutral. The examiner grasps the patient's thumb and gently moves the hand into ulnar deviation, taking the thumb into flexion and adduction. This is Finkelstein's original description.

Positive Finding

Sharp pain over the radial styloid along the first dorsal compartment tendons (abductor pollicis longus and extensor pollicis brevis), reproducing the patient's pain.

Interpretation

Supports de Quervain's tenosynovitis. Pain can also come from the thumb base (CMC joint) or other radial-sided wrist structures, so check exactly where it hurts and compare with the other side. The reference previously shown for this test could not be matched to any published paper and has been withdrawn. A literature search (Europe PMC, September 2026) found no study reporting the diagnostic accuracy of this test, so no figure is shown. Note: the manoeuvre commonly taught as Finkelstein's (thumb tucked into the fist, then ulnar deviation) is Eichhoff's test; Finkelstein's original description differs.

Eichhoff's Test

Procedure

The patient tucks the thumb into the palm and closes the fingers over it. The examiner then moves the wrist into ulnar deviation.

Positive Finding

Pain over the radial styloid along the first dorsal compartment, reproducing the patient's familiar pain.

Interpretation

Supports de Quervain's tenosynovitis. It stretches the tendons hard and can be uncomfortable in unaffected wrists too, so compare with the other side and judge whether it reproduces the patient's own pain. The reference previously shown for this test could not be matched to any published paper and has been withdrawn. No accuracy figure is shown because none has yet been checked against a study.

Radial Fillet Sign (Palpation)

Procedure

Palpate the first dorsal compartment over the radial styloid and just proximal to it, following the abductor pollicis longus and extensor pollicis brevis tendons. Compare with the other side.

Positive Finding

Localised tenderness, often with palpable thickening of the tendon sheath, over the radial styloid.

Interpretation

Local tenderness with sheath thickening supports de Quervain's tenosynovitis. Tenderness a few centimetres more proximal, where the thumb tendons cross the radial wrist extensors, points to intersection syndrome instead. 'Radial fillet sign' is not a standard name; this is palpation of the first dorsal compartment. A literature search (Europe PMC, September 2026) found no study reporting the diagnostic accuracy of this test, so no figure is shown.

No accuracy study

Crepitus Test

Procedure

Rest your fingers over the first dorsal compartment while the patient repeatedly moves the thumb through abduction–adduction and flexion–extension.

Positive Finding

Palpable creaking or grating over the first dorsal compartment with thumb movement.

Interpretation

Crepitus is an occasional supporting finding in tenosynovitis; its absence means little. Crepitus felt a few centimetres above the wrist on the back of the forearm suggests intersection syndrome.

Radial Deviation with Thumb Opposition Test

Procedure

Not a recognised named test. One reasonable version: the patient holds a firm pinch between thumb and index finger and moves the wrist from neutral into radial deviation against light resistance, loading the first dorsal compartment tendons.

Positive Finding

Pain over the first dorsal compartment during the resisted movement.

Interpretation

Pain on loading supports first dorsal compartment irritation, but this is not a validated test. Rely on Finkelstein's or Eichhoff's test and local palpation instead.

Wrist Ulnar Deviation with Thumb Flexion

Procedure

The examiner holds the patient's thumb flexed across the palm (without asking the patient to make a fist) and gently moves the wrist into ulnar deviation.

Positive Finding

Pain over the radial styloid along the first dorsal compartment.

Interpretation

A variant of Finkelstein's and Eichhoff's tests that stretches the same tendons. It adds little if either of those has already been done.

⚠ Red Flags

  • •Severe swelling with signs of compartment syndrome or vascular compromise
  • •Systemic symptoms suggesting rheumatoid arthritis or other inflammatory arthropathy
  • •Traumatic onset with associated fracture
  • •Signs of infection (fever, spreading erythema, warmth)
  • •Neurological symptoms suggesting nerve compression
  • •Failure to improve after 6-8 weeks of conservative treatment with imaging findings suggesting advanced pathology

⚡ Yellow Flags

  • •High job demand with limited accommodation for modification
  • •Catastrophizing about loss of hand function
  • •Poor adherence to activity modification due to occupational pressure
  • •Significant psychological distress related to functional limitation
  • •Belief that condition requires early surgery despite good conservative prognosis

Osteopathic Techniques

De Quervain tenosynovitis can settle on its own. Persistent cases are treated with a splint, anti-inflammatories and steroid injection; a removable semi-rigid splint is preferred over strict rigid immobilisation. In a network meta-analysis, a full-time orthosis plus steroid injection ranked best, on low-certainty evidence. No trials of osteopathic techniques were found.

Region

First dorsal compartment (APL and EPB) and radial wrist

Technique

Soft tissue, wrist and handNo trials found

Rationale

Soft tissue to the wrist and hand: flexor retinaculum, palmar fascia, thenar and intrinsic muscles.

How it's done, cautions & evidence

How it's done

Hands-on kneading, stroking and sustained pressure to the soft tissues of the wrist and hand: the flexor retinaculum and thenar muscles over the carpal tunnel, the first dorsal compartment, the wrist ligaments, the palmar fascia, the hand intrinsics and the finger flexor sheath at the A1 pulley. In carpal tunnel trials, soft tissue mobilisation was often combined with neural mobilisation.

Cautions

In Guyon canal syndrome, avoid prolonged pressure over the hypothenar eminence. After a fall on the hand, rule out a fracture first: scaphoid fractures are often missed on the first X-ray.

Evidence in De Quervain's Tenosynovitis

Region

Radiocarpal, midcarpal and thumb CMC joints

Technique

Articulation, wrist and handNo trials found

Rationale

Gentle glides of the wrist, carpal and hand joints to restore movement.

How it's done, cautions & evidence

How it's done

Passive, rhythmic, low-velocity glides of the radiocarpal, midcarpal and intercarpal joints, the distal radioulnar joint, the thumb carpometacarpal (CMC) joint and the finger joints, within or up to the end of the available range. In thumb-base osteoarthritis trials this was Maitland-style passive accessory gliding of the CMC joint.

Cautions

After a fall on the hand, rule out a fracture first: scaphoid fractures are often missed on the first X-ray, so snuffbox pain needs a splint and repeat imaging. Do not move a joint that is splinted for a tendon injury: the DIP in mallet finger, the PIP in a central slip (boutonnière) injury.

Evidence in De Quervain's Tenosynovitis

Searched 26 Oct 2026: no trials of wrist or thumb mobilisation in De Quervain tenosynovitis.

Region

Wrist and forearm muscles

Technique

Muscle energy, elbow and forearmNo trials found

Rationale

Muscle energy technique to ease tight forearm muscles that act on the wrist (wrist extensors or flexors, pronators or supinators).

How it's done, cautions & evidence

How it's done

The wrist or forearm is taken to the barrier of the tight muscle group (wrist extensors or flexors, pronators or supinators). The patient pushes gently back, at about 10–20% effort, against resistance for 5–10 seconds, relaxes for 3–5 seconds, and the new barrier is taken up.

Cautions

Not used with an acute fracture, a joint infection or a bone malignancy; take care with severe osteoporosis or after surgery that limits muscle contraction. Use the least force needed: too much can tear a muscle or pull off a tendon, especially in older patients.
