The Anatomy Of The Pedicle Of The Cervical Vertebra

Description

Arising from the posterolateral margin of the cervical vertebral body, the pedicle is presented as a short, stout bony bridge running posteriorly to meet the laminae and complete the vertebral arch. As the sequence rotates and steps through the posterior elements, the superior and inferior vertebral notches on the pedicle margins become the intervertebral foramen when paired with the adjacent level. Facet joints appear posterior to the pedicles at the articular pillars, while the transverse processes extend laterally, framing the vertebral foramen medial to both pedicles. Pedicle anatomy in the neck is where “small differences” turn into real operative risk. Cervical pedicle screw placement demands strict appreciation of pedicle width, medial angulation, and the relationship of the pedicle to the spinal canal medially and the transverse foramen laterally, where the vertebral artery typically ascends from C6 to C1. The animated progression clarifies how the pedicle is not just a connector but the bony corridor between anterior column and posterior elements, and why breach can threaten the spinal cord, exiting nerve root, or vertebral artery. Use this animation for spine modules in gross anatomy or neuroanatomy courses, for radiology teaching when correlating axial CT with pedicle morphology, and for surgical education around posterior cervical instrumentation and decompression planning. It also reads well in publisher content on cervical spondylosis, traumatic instability, and preoperative navigation concepts. Anatomical accuracy verified by SciePro's Medical Advisory Board.
