Cervical Foraminotomy Of The Human Cervical Vertebra

Description

Cervical intervertebral foramina are the focus of this postoperative illustration, with one neural foramen surgically widened by a foraminotomy through the posterolateral elements of a cervical vertebra. The pedicles form the superior and inferior borders of the foramen, while the vertebral body and uncovertebral region lie anteriorly and the zygapophysial (facet) joint with adjacent lamina sits posteriorly, framing the bony window. Within the enlarged opening, the expected course of the exiting cervical spinal nerve root is appreciated lateral to the thecal sac and spinal canal. Bone margins at the facet-lamina junction appear recontoured to increase foraminal caliber. Cervical foraminotomy is a workhorse decompressive procedure for unilateral cervical radiculopathy when foraminal stenosis from osteophytes, facet hypertrophy, or a posterolateral disc-osteophyte complex impinges the exiting nerve root. Orientation matters. By emphasizing the relationship of the widened foramen to the facet joint and pedicle, the illustration helps communicate how far lateral decompression can proceed before approaching the transverse foramen region, where the vertebral artery lies at risk, and how excessive facet removal can contribute to postoperative segmental instability. Use this illustration for neurosurgery and orthopaedic spine teaching on posterior cervical approaches, for figure panels in operative technique manuscripts discussing foraminal stenosis, or for patient-facing explanations of why arm pain can persist until the exiting nerve root is decompressed. It also suits exam material on cervical spine bony landmarks and surgical corridors. Anatomical accuracy verified by SciePro's Medical Advisory Board.
