Comparison of Corticosteroid Injection, Nighttime Splinting, or Their Combination for Initial Treatment of Moderate-to-Severe Carpal Tunnel Syndrome

Официальное название

Comparison of Corticosteroid Injection, Nighttime Splinting, or Their Combination for Initial Treatment of Moderate-to-Severe Carpal Tunnel Syndrome: A Pragmatic, Three-Armed, Open-Label, Multicenter, Randomized Clinical Trial

Обзор

The goal of this clinical trial is to compare the efficacy of corticosteroid injection, night splinting, and their combined use as initial treatments for adults with moderate to severe carpal tunnel syndrome (CTS), and to assess the safety and tolerability of these interventions. The primary research questions include: * Doe corticosteroid injection, night splinting, and their combined use as initial treatments reduce the need for surgery in participants with moderate to severe CTS? * How do these interventions affect the improvement of patient symptoms? Participants will: * Receive corticosteroid injection, night splinting, or their combination as initial treatments. * Visit the clinic once every 6 weeks over a period of one year for assessments and dynamic adjustment of the treatment plan. * Undergo periodic assessments of wrist function, quality of life, and sleep quality using standardized questionnaires.

Вмешательства

• Устройство Nighttime Splinting
  Nighttime splinting for 6 weeks.
• Препарат Corticosteroid Injection
  Local corticosteroid injection (triamcinolone acetonide 40mg). A single injection of triamcinolone acetonide 40mg mixed with an equal volume of 1% lidocaine is administered. The injection is performed under ultrasound guidance and anatomical landmarks to target the proximal carpal tunnel. With the wrist extended, the needle is typically inserted on the ulnar side of the palmaris longus tendon, approximately 1 cm proximal to the wrist crease. If blood is aspirated or the patient reports paresthes
• Другое Evaluation and Dynamic Adjustment
  6 weeks later, all patients will undergo evaluation of their initial treatment. Further therapeutic decisions will be made based on physician assessment, including: continuing nighttime splinting, administering corticosteroid injections to patients who initially received only the splint, adding nighttime splinting for patients initially received only corticosteroid injections, and transitioning from nighttime splint use to continuous wear. Subsequently, evaluations will be conducted every 6 week
