Figure 14: Transverse scan of the cervical spine at the level of C6 for needle placement. The centroid of the articular pillar forms a distinct flat hyperechoic line and constitutes the target for cervical medial branch blocks. The semispinalis capitis muscle inserts on the posterior tubercle of the transverse process and courses over the AP. Further anterior, nerve root and anterior tubercle can be seen. A computed tomography overlay of the same bony landmarks is depicted in the right lower inset. When performing a cervical medial branch block, the injectate should be deposited along the periosteum of the articular pillar, beneath the SSC.
