Cervical Foraminotomy In Anatomical View

Description

Oblique posterior views of the cervical spine progress through a foraminotomy sequence, keeping the vertebral arch and lateral mass centered while the intervertebral foramen is opened. The animation tracks the relationship of the pedicle superior and inferior, the facet (zygapophysial) joint posteriorly, and the uncovertebral region anterolaterally as the bony corridor is widened. As bone is removed from the lamina and medial facet, the exiting cervical spinal nerve root comes into clearer relief within the enlarged foramen, adjacent to the dorsal root ganglion and bordered by the perineural fat. Orientation remains anchored to the midline spinous processes and the lateral transverse processes so left versus right laterality reads immediately. Posterior cervical foraminotomy is a workhorse operation for unilateral radiculopathy from foraminal stenosis, most often due to osteophytes or a laterally placed disc herniation at C5 to C6 or C6 to C7. Seeing the decompression evolve frame by frame clarifies what surgeons mean by “undercutting” the medial facet while preserving enough of the facet joint to limit postoperative instability. It also highlights why the exiting root is at risk during drilling and Kerrison work, and how the safe bony boundaries relate to the vertebral artery anterior to the foramen transversarium. Use this animation in spine surgery teaching modules, neurosurgery and orthopedic residency conference slides, and medical publishing projects covering cervical radiculopathy, foraminal stenosis, and minimally invasive posterior approaches to the neck. It also fits patient education for planned foraminotomy when paired with dermatomal pain patterns and postoperative activity guidance. Anatomical accuracy verified by SciePro's Medical Advisory Board.
