Anatomical Presentation Of A Cervical Foraminotomy, Posterior View

Description

Cervical vertebral laminae and facet joints frame a posterior surgical field in which a foraminotomy has been performed to open the intervertebral foramen. Along the posterolateral margin of the spinal canal, the bony roof over the nerve root has been excised at the junction of the lamina and superior articular process, creating a widened corridor toward the pedicle. The exiting cervical spinal nerve is positioned lateral to the dural sac, with the decompressed zone centered just inferior to the facet joint and medial to the transverse process. Bone edges are sharply defined. Posterior cervical foraminotomy is a standard decompression for unilateral cervical radiculopathy from foraminal stenosis, uncovertebral or facet osteophytes, and lateral disc herniation where motion preservation is preferred over fusion. The fixed posterior perspective emphasizes the anatomic tradeoff surgeons manage, enough bone removal to free the nerve root while limiting facet resection to reduce the risk of postoperative segmental instability. Orientation to landmarks is immediate, and you can judge how the working window relates to the medial facet, the lateral recess, and the expected location of the dorsal root ganglion. Small margins matter. Neurosurgery and orthopaedic spine teaching materials can pair this illustration with discussions of minimally invasive tubular approaches, keyhole laminoforaminotomy, and postoperative complications such as persistent foraminal stenosis or iatrogenic C5 palsy. Medical publishers will also find it well suited for captions contrasting posterior foraminotomy with anterior cervical discectomy and fusion (ACDF) in the setting of foraminal narrowing and nerve root compression.
