De Quervain's Release

Why this approach — at MOS

De Quervain's release is a straightforward procedure in experienced hands, but the most common cause of failure is an incomplete release — specifically, leaving an intact EPB subcompartment that continues to constrict the extensor pollicis brevis tendon after the main compartment is opened. At Maryland Orthopedic Specialists, identifying and releasing any subcompartment is a routine step in the procedure, not an afterthought.

Protection of the radial sensory nerve branches is equally critical. These small sensory branches run directly over the first dorsal compartment, and a careless incision or retraction that injures them can produce a painful neuroma — a complication that is more problematic than the original De Quervain's symptoms. Careful dissection with identification and gentle retraction of these nerve branches before the compartment is released prevents this avoidable complication.

The Finkelstein test remains the most reliable physical examination test for De Quervain's, and a clinical diagnosis confirmed by this test — combined with the appropriate history of activity-related thumb-side wrist pain — is sufficient to plan surgery in a patient who has failed appropriate conservative measures. MRI or ultrasound may be used selectively to distinguish De Quervain's from basal joint arthritis or intersection syndrome, which are treated differently.

Patients at our Germantown, Bethesda, and Rockville offices can usually be seen promptly and, in appropriate cases, scheduled for this procedure efficiently given its short operative time and outpatient setting.

Who is a candidate?

Indications

• Persistent De Quervain's tenosynovitis symptoms for 3–6 months despite splinting and anti-inflammatory medication
• Failure of at least one corticosteroid injection, or recurrence after initial improvement
• Bilateral De Quervain's requiring treatment of the dominant hand in a patient who cannot sustain a prolonged splinting program
• Anatomic subcompartment variation identified on imaging (increases likelihood of injection failure)

Contraindications

• Active skin infection over the radial wrist
• Symptoms that have not received a trial of conservative treatment
• Inflammatory arthritis insufficiently controlled — flares will drive recurrence regardless of release

Conservative Treatment First

De Quervain's tenosynovitis responds well to conservative measures in many patients. A thumb spica splint — immobilizing the wrist and thumb in a resting position — reduces the mechanical irritation that aggravates the tendons and often resolves mild to moderate symptoms over 4–6 weeks. Combined with oral anti-inflammatory medications, splinting is a reasonable first measure.

Corticosteroid injection into the first dorsal compartment is the most effective non-surgical treatment. A single injection provides lasting relief in 50–80% of patients. For patients with a subcompartment (an extra dividing wall between the APL and EPB tendons, present in up to 30% of people), a single injection may not reach both tendons — this anatomic variation increases the injection failure rate and is one reason some patients respond to surgery after failing injections. A second injection can be tried if the first provides partial benefit. When two injections have not provided lasting relief, surgical release is appropriate.

The procedure

What Is De Quervain's Release?

De Quervain's release is a quick outpatient surgery that opens the first dorsal compartment of the wrist — a tight tunnel at the base of the thumb — to relieve the pain and swelling of De Quervain's tenosynovitis. It is performed under local anesthesia when injections and splinting have not resolved the condition.

De Quervain's tenosynovitis (pronounced deh-kwer-VANZ) is a painful condition affecting two tendons that run along the thumb side of the wrist: the abductor pollicis longus (APL) and the extensor pollicis brevis (EPB). These tendons pass through a narrow fibrous tunnel — the first dorsal compartment — just above the radial styloid (the bony prominence on the thumb side of the wrist). When the tunnel becomes constricted or the tendons become thickened, they cannot glide smoothly, causing pain, swelling, and tenderness directly at the base of the thumb and wrist. The pain worsens with pinching, gripping, and lifting, and is typically reproduced by the Finkelstein test — wrapping the thumb in the fingers and bending the wrist toward the little finger side.

De Quervain's tenosynovitis is especially common in new mothers (from repeated lifting and holding of infants), in workers who perform repetitive pinching and gripping, and in patients with inflammatory arthritis. It should not be confused with basal joint arthritis (arthritis at the thumb carpometacarpal joint), which causes similar-sounding symptoms but in a slightly different location and requires different treatment.

What Happens During De Quervain's Release?

Setting: De Quervain's release is an outpatient procedure performed under local anesthesia. No sedation or general anesthesia is typically required. The procedure takes 15–30 minutes.

Positioning: The hand is placed palm-down on a padded arm board. A tourniquet or tight dressing on the wrist controls bleeding.

Procedure: A small transverse or oblique incision — approximately 2 cm — is made directly over the first dorsal compartment, just proximal to the radial styloid. The incision is deepened carefully to identify the radial sensory nerve branches, which cross directly over the compartment and must be protected to avoid a painful neuroma. The first dorsal compartment retinaculum is identified and divided on its dorsal surface along the full length of the compartment.

A critical step is identifying whether a subcompartment is present — a separate fibrous wall dividing the EPB tendon into its own channel separate from the APL tendons. If present, this septum must be divided independently. Failure to release a subcompartment is the most common cause of persistent symptoms or "recurrence" after De Quervain's release. The APL often has multiple tendon slips (2–4 slips are common), all of which must be confirmed within the released compartment. The tendons are inspected and confirmed to glide freely. The wound is closed and a light dressing applied.
