Cervical medial branch blocks also can produce anesthesia of cervical facets. These medial branches of the cervical dorsal rami travel across the waist of the articular pillars (a point proximal to the origin of the articular branches). Here, the nerves have a constant relationship to bone and are more easily accessible by either a posterior or lateral approach. See the image below.
