Uncinate Process Of The Cervical Vertebra, Anatomy

Description

Uncinate processes (uncus corporis) rise as sharp, lip-like elevations along the superolateral margins of a cervical vertebral body, framing the superior endplate on its right and left sides. Each uncus sits medial to the pedicle and transverse process and lateral to the central vertebral body, creating a guttered contour that guides the articulation with the inferolateral aspect of the vertebral body above. The illustration centers this bony ridge and its relationship to the adjacent vertebral body surface, clarifying how the uncinate process defines the medial boundary of the uncovertebral region. Uncovertebral joints (joints of Luschka, typically C3 to C7) concentrate degenerative change, and hypertrophy or osteophyte formation along the uncinate process is a common structural source of foraminal narrowing in cervical spondylosis. That anatomy matters when correlating unilateral neck pain with C5 to C7 radiculopathy, or when interpreting CT and MRI findings where an uncovertebral osteophyte complex can be mistaken for a pure disc-osteophyte ridge. Small structure, big symptoms. The focused bony detail helps you distinguish the uncus from the adjacent endplate and appreciate why the uncinate margin lies close to the intervertebral foramen and, more laterally, the transverse foramen that transmits the vertebral artery. Use this illustration for spine anatomy teaching in gross anatomy and musculoskeletal modules, for radiology atlases discussing cervical foraminal stenosis, and for surgical education materials supporting anterior cervical discectomy and fusion (ACDF) planning where uncinate resection or foraminotomy may be considered.
