Comparing Efficacies of Median Nerve Hydrodissection With Dexamethasone and Dextrose in Carpal Tunnel Syndrome

Injected wrist will be supinated and slightly dorsiflexed. The transducer of the ultrasound will be placed transversely at the proximal carpal inlet. After sterile preparation, a 22 gauge needle will be inserted using the short-axis technique, in-plane ulnar approach. During hydrodissection, separation of either between the median nerve and flexor retinaculum or between the median nerve and the underlying flexor tendons will be visually confirmed.
