Overview

De Quervain tenosynovitis affects the abductor pollicis longus (APL) and extensor pollicis brevis (EPB) tendons in the first dorsal compartment. Surgical release decompresses the constricting retinaculum and any separate EPB subsheath while retaining a volar restraint against tendon subluxation. Anatomic variation is common and incomplete identification of the compartments is an important cause of persistent symptoms (Campbell, Chapter 81).

Assessment and Indications

  • Confirm radial styloid tenderness, a compatible history and provocative findings. A positive Finkelstein-type maneuver alone is not diagnostic.

  • Consider thumb-base, scaphotrapeziotrapezoid or radiocarpal arthritis, intersection syndrome and superficial radial nerve pathology as alternative causes.

  • Appropriate nonoperative treatment includes splinting and corticosteroid injection; persistent symptoms after this pathway may justify release.

  • Review previous procedures, injections and sensory symptoms. Ultrasound can help clarify compartment anatomy or an uncertain diagnosis in the treatment pathway described by the source.

  • Discuss scar sensitivity, cutaneous nerve injury, incomplete release and tendon instability.

(Campbell, Chapter 81.)

Relevant Anatomy

Structure

Importance during release

Superficial radial sensory branches

Cross the operative region and require careful superficial dissection.

Lateral antebrachial cutaneous branches

Can also be encountered superficially near the cephalic vein.

EPB subsheath

May remain constricted after the apparent main compartment has been opened.

Multiple APL slips

Common variation; identify all relevant tendon compartments.

Radial artery

Runs deeper beyond the styloid and is vulnerable during deep or distal dissection.

Volar retinacular flap

Retaining it helps prevent volar tendon subluxation.

(Campbell, Chapter 81.)

Anesthesia and Setup

  1. Use a local anesthetic approach with suitable hemostasis. The source describes a tourniquet or local anesthetic with epinephrine as alternatives.

  2. Infiltrate the skin proximal to the compartment before preparation and draping.

  3. Position the wrist and thumb so the tendons can be examined dynamically after release.

  4. Mark an incision that permits direct identification of the retinaculum while respecting superficial nerve branches.

(Campbell, Chapter 81, Technique 81.1.)

Surgical Technique

Skin and Superficial Dissection

  1. Make a controlled skin incision. Campbell accepts transverse, oblique or longitudinal options and describes an oblique approach along the EPB region.

  2. Carry sharp dissection only through the dermis, then use blunt spreading in the subcutaneous tissue.

  3. Identify and protect the cutaneous nerves rather than extending a sharp cut through the fat.

  4. Expose the retinaculum sufficiently to define the compartment and its proximal and distal limits.

(Campbell, Chapter 81, Technique 81.1.)

Release and Identify Both Tendons

  1. Identify the first-compartment tendons proximal to the constricting sheath.

  2. Open the compartment on its dorsoulnar side, preserving a volarly based flap.

  3. Identify EPB and APL separately. In the source, EPB lies dorsally and may show distally extending muscle fibers, whereas APL does not in this region.

  4. Release the EPB region and inspect for a septum or independent subsheath before assuming the whole compartment is decompressed.

  5. With thumb abduction and wrist flexion, gently lift the tendons from the groove. Difficulty doing so should prompt a search for an unreleased compartment or additional tendon slips.

  6. Complete the necessary decompression under vision, avoiding the deep radial artery.

(Campbell, Chapter 81, Technique 81.1.)

Check Excursion and Stability

  1. Confirm that each relevant tendon is free through the released region.

  2. Inspect for a separate EPB tunnel and remaining constricting septal fibers.

  3. Ensure that the volar retinacular flap remains over the tendons to limit volar subluxation.

  4. Assess tendon motion without converting the release into excessive retinacular excision.

  5. Close the skin and apply a small pressure dressing.

(Campbell, Chapter 81.)

Final Checks

  • APL and EPB have both been identified or their anatomic variation has been established.

  • No separate constricting subsheath has been missed.

  • Superficial sensory nerves and the radial artery have been protected.

  • Tendon excursion is free and the retained flap provides an appropriate volar restraint.

  • The skin closure and dressing do not compromise early comfortable motion.

(Campbell, Chapter 81.)

Postoperative Care

In Technique 81.1, the small pressure dressing is removed after about 48 hours, with another light dressing if needed. Thumb and hand motion begin immediately and progress as tolerated. Avoid forceful wrist flexion during the first 2 weeks because it can predispose the released tendons to subluxation (Campbell, Chapter 81).

Persistent Symptoms and Recurrence

When symptoms persist, reassess the diagnosis and consider an unrecognized subsheath or accessory tendon, neural adhesion or neuroma, scar hypertrophy and volar tendon subluxation. These are different problems and do not all respond to a more extensive repeat release (Campbell, Chapter 81).

Symptomatic tendon instability may require a reconstructive restraint, such as a retinacular or brachioradialis-based technique described in the chapter. Revision should address the demonstrated cause rather than simply remove more sheath.

Pearls and Pitfalls

  • Protect nerves at the skin level: a technically complete tendon release can still leave disabling neuropathic scar pain.

  • Look for the EPB tunnel: opening only the main APL-containing compartment may leave the symptomatic constriction intact.

  • Respect tendon variation: multiple APL slips are common.

  • Retain a volar flap: complete uncontrolled excision increases the risk of tendon instability.

  • Check the original diagnosis: radial-sided wrist pain has several causes.
