Short-Term Effectiveness of Ultrasound-Guided Corticosteroid Hydrodissection

Short-Term Effectiveness of Ultrasound-Guided Corticosteroid Hydrodissection in Patients With Carpal Tunnel Syndrome

Aim: Steroid injections are remarkably effective as a treatment for carpal tunnel syndrome (CTS) in the short term. The aim of this study was to determine whether hydrodissection would provide an additional clinical effect when used along with a corticosteroid in the short term.

Methods: A prospective cohort of patients with CTS were retrospectively evaluated. 28 patients were selected randomly who received ultrasound (US)-guided triamcinolone hydrodissection (3 mL) as intervention group and received US-guided triamcinolone injection (1 mL) as control group, from the data (case-control ratio 1:1). Outcome measures were the Boston Carpal Tunnel Questionnaire (BCTQ), hand grip strength (HGS), fhe cross-sectional area (CSA) of the median nerve and Short Form 12 (SF-12). Assessments were recorded at baseline, 1 and 4 weeks after injection.
