Randomized Controlled Trial
Therapeutic cervical medial branch blocks in managing chronic neck pain: a preliminary report of a randomized, double-blind, controlled trial: clinical trial NCT0033272.
Based on the criteria established by the International Association for the Study of Pain, the prevalence of persistent neck pain, secondary to involvement of cervical facet or zygapophysial joints has been described in controlled studies as varying from 54% to 67%. Intraarticular injections, medial branch nerve blocks and neurolysis of medial branch nerves have been described in managing chronic neck pain of facet joint origin. ⋯ Therapeutic cervical medial branch nerve blocks, with or without Sarapin or steroids, may provide effective management for chronic neck pain of facet joint origin.
