Cervical Median Branch Blocks

Cervical median branch blocks are diagnostic injections designed to help localize the cause of certain types of neck pain and posterior headaches. The involve the accurate placement of 2 or more needles and the injection of tiny amounts of local anesthetic.

Cervical median branch blocks are diagnostic injections to help localize the nerves, which are either generating or carrying the pain signals in cases of primarily axial neck pain and cervicogenic headaches. They also help answer the question of whether ablation of these nerves will cause unacceptable side effects, such as nausea or balance problems. If not, long term inactivation of these nerves using radiofrequency ablation (RFA) or cryoablation can be considered.
