Extensor Retinaculum Wrist Injury: Conservative and Surgical Treatment Options

The extensor retinaculum holds extensor tendons in place at the wrist. Tears cause tendon subluxation, pain, and weakness.

Conservative Management (Partial Tears, Low Demand)

• Immobilization: wrist brace/orthosis in neutral (4–6 weeks).
• Activity modification: avoid repetitive extension, gripping.
• NSAIDs, ice for inflammation.
• Hand therapy: tendon glides, progressive strengthening.
• Ultrasound-guided corticosteroid injection if tenosynovitis.

Surgical Indications

• Complete tear with tendon subluxation.
• Failed conservative treatment (3–6 months).
• High-demand athletes/workers.
• Associated fractures, ganglion cysts.

Surgical Techniques

• Direct repair: Suture retinaculum (transverse incisions, bone anchors).
• Reconstruction: Local tissue (extensor digitorum communis slip), allograft, or synthetic graft if attenuated.
• Arthroscopic-assisted: Visualization, less dissection; emerging.

Post-Op Protocol

• Immobilization 2–4 weeks.
• Progressive ROM → strengthening (6–12 weeks).
• Return to sport/work: 3–6 months.

Outcomes

Good-excellent in 80–90% with anatomic repair. Recurrence risk higher with reconstruction. Early diagnosis improves outcomes.
