Uncinate Process

Description[edit | edit source]

An Uncinate Process of a vertebra is a hook-shaped process on the posterolateral borders of the superior surface of the vertebral bodies of the third to the seventh cervical vertebrae and first thoracic vertebra. Luschka's joints involve the vertebral uncinate processes.

Function[edit | edit source]

  • prevents posterior linear translation movements of the vertebral bodies
  • reinforces the disc posterolaterally
  • limits lateral flexion (side-bending).
