Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study was a prospective randomized double-blind clinical trial conducted at the Physical Medicine and Rehabilitation Clinic of a local research and training hospital in Turkey from October 2023 and May 2024. Patients diagnosed with CTS were classified into three groups: severe, mild, and moderate CTS, based on the results of electrophysiological tests. An ultrasound-guided 5% Dextrose in Water injection was performed. The primary outcome measurement was the Visual Analog Scale (VAS), while secondary measurements were the Boston Carpal Tunnel Syndrome Questionnaire (BCTQ) and the Dolour Neuropathic en 4 Questions (DN4) questionnaire. The measurements were performed before the injection and at the first week, first month and third month follow-up times. The distribution of data within groups was examined using the Shapiro-Wilk test and Q-Q plots. The study also analyzed temporal changes, group differences, and intergroup changes using repeated measures ANOVA models.

Group 1

Mild Carpal Tunnel syndrome

Group Type ACTIVE_COMPARATOR

Carpal Tunnel Hydrodissection with %5 dextrose in water injection

Intervention Type DRUG

Under the inplane ulnar approach, 3ml injectate was injected to hydrodissect the median nerve from the flexor retinaculum, and the residual 2ml injectate was then injected to hydrodissect the inferior median nerve away from the flexor tendons.

Group 2

Moderate Carpal Tunnel Syndrome

Group Type ACTIVE_COMPARATOR

Carpal Tunnel Hydrodissection with %5 dextrose in water injection

Intervention Type DRUG

Under the inplane ulnar approach, 3ml injectate was injected to hydrodissect the median nerve from the flexor retinaculum, and the residual 2ml injectate was then injected to hydrodissect the inferior median nerve away from the flexor tendons.

Group 3

Severe Carpal Tunnel Syndrome

Group Type ACTIVE_COMPARATOR

Carpal Tunnel Hydrodissection with %5 dextrose in water injection

Intervention Type DRUG

Under the inplane ulnar approach, 3ml injectate was injected to hydrodissect the median nerve from the flexor retinaculum, and the residual 2ml injectate was then injected to hydrodissect the inferior median nerve away from the flexor tendons.
