Vitamin for CTS

Details and patient eligibility

About

Carpal tunnel syndrome (CTS) is the most common peripheral entrapment neuropathy with involving compression of the median nerve in the carpal tunnel. Rather than other progressive disease, CTS is characterized by remission and recurrence. The hydrodissection could decrease the entrapment of nerve to restore blood supply. In addition, the Vitamin B12 was considered to be beneficial for peripheral neuropathy and pain relief. The investigators design a randomized, double-blind, controlled trail to assess the effect after ultrasound-guided hydrodissection with Vitamin B12 in patients with CTS.

Full description

After obtaining written informed consent, patients with mild to moderate CTS will been randomized into intervention and control group. Participants in intervention group received one-dose ultrasound-guided hydrodissection with 3cc Vitamin B12 and control side received one-dose ultrasound-guided injection 3cc normal saline. No additional treatment after injection through the study period. The primary outcome is Boston Carpal Tunnel Syndrome Questionnaire (BCTQ) and secondary outcomes include visual analog scale (VAS), cross-sectional area (CSA) of the median nerve, sensory nerve conduction velocity of the median nerve. The evaluation was performed pretreatment as well as on the 2nd week, 1st, 2nd, 3rd and 6th month after the treatment.
