Answer

Intra-articular cervical zygapophyseal joint blocks should be performed by a highly skilled interventionist experienced with the use of fluoroscopy for needle placement. They are usually performed as a diagnostic maneuver to prove that a specific facet-joint is in fact the source of pain. Intra-articular cervical facet blocks are primarily used for diagnostic maneuvers (eg, to prove that a specific facet joint is the source of pain). [19]

Facet pathology is commonly presumed to be salient when pursuing localization of a primarily axial neck pain source. Blind injection techniques are no longer considered the standard of care because of the accessibility of fluoroscopy. The C3-4 to C6-7 levels can be approached using either a posterior or lateral approach. Only the lateral approach is in feasible for the C7-T1 joint because of the obligatory steep slope approach. An oblique approach to the C2-3 zygapophyseal level is necessary because the joint tends to slope caudally and medially. [20]
