Superior Vertebral Notch Of The Cervical Vertebra, Anatomy

Description

Cervical vertebral pedicle anatomy is centered here on the superior vertebral notch, the shallow concavity along the superior border of the pedicle that contributes to the intervertebral foramen. The notch sits posterolateral to the vertebral body and anteromedial to the superior articular process, with the lamina extending posteriorly toward the spinous process. Nearby landmarks that help orient the viewer include the vertebral foramen, transverse processes with the foramen transversarium, and the inferior vertebral notch on the pedicle below. Small structure, big implications. In the cervical spine, the superior and inferior vertebral notches from adjacent vertebrae form the bony margins of the intervertebral foramen, the passageway for the exiting spinal nerve and accompanying radicular arteries and veins. Foraminal stenosis from uncovertebral osteophytes, facet arthrosis, or disc height loss can narrow this corridor and provoke cervical radiculopathy, so a precise understanding of the pedicle’s borders and their relationship to the articular pillar matters when correlating symptoms to level. Crisp surface relief on the pedicle and posterior elements in a fixed perspective helps clarify where surgeons work during posterior cervical foraminotomy and where instrumentation must avoid breaching the foramen during lateral mass or pedicle screw planning. Use this illustration in gross anatomy and neuroanatomy teaching to explain how the intervertebral foramen is built from paired notches, and in spine surgery texts or device training materials to label pedicle-based landmarks with Terminologia Anatomica nomenclature. It also suits radiology education when pairing osseous boundaries on CT with expected locations of the exiting nerve root in the lower cervical levels.
