Case Reports
Progressive severe kyphosis as a complication of multilevel cervical percutaneous facet neurotomy: a case report.
Percutaneous facet neurotomy is a procedure commonly used for the treatment of pain thought to originate from zygoapophyseal joint dysfunction. Some practitioners have also used this technique to treat cervicogenic headache. Previously reported complications for this procedure have been minimal and have included dysthesias and local pain. ⋯ When performing multilevel percutaneous cervical facet neurotomies, there is a risk of paraspinous muscle denervation, and subsequent kyphotic deformity may occur. The likelihood of this rare and previously unreported complication can probably be reduced by proper needle positioning and by minimizing the number of levels at which the procedure is performed.
