De Quervain Tendinopathy: Anatomical Prognostic Indicators of Corticosteroid Injection Success

Area of Science:

• Orthopedic Surgery
• Musculoskeletal Imaging
• Rheumatology

Background:

• Anatomical variations in the first extensor compartment influence de Quervain tendinopathy outcomes.
• Identifying prognostic indicators for symptom recurrence post-corticosteroid injection is crucial.

Purpose of the Study:

• To identify anatomical prognostic indicators of de Quervain tendinopathy recurrence after corticosteroid injection.
• To assess the efficacy of corticosteroid injections for de Quervain tendinopathy.

Main Methods:

• Fifty patients with de Quervain tendinopathy received a single corticosteroid injection.
• Ultrasound imaging assessed anatomical factors of the first extensor tendon compartment.
• Symptom recurrence, DASH, and VAS scores were evaluated post-injection.

Main Results:

• Fifteen patients (30%) experienced recurrence within six weeks.
• Intracompartmental septum and multiple tendon slips predicted higher recurrence rates.
• Significant improvements were observed in DASH and VAS pain scores (p < 0.01).

Conclusions:

• Corticosteroid injections are a viable treatment for de Quervain tendinopathy.
• Anatomical variations predict treatment success and recurrence risk.
• Patient counseling based on anatomical factors can guide treatment choices, including surgery.
