Cervical Spine Injuries, Fractures and Whiplash - Disc Protrusions

Grading System for Disc Protrusions

Written by Wolfgang Rauschning, MD

Our Grading System for disc protrusions is based on the assessment of the normal specimens and actual disc herniations.

Grade 0: straight contour of the posterior annulus fibrosus.

Grade 1: small annulus fibrosus protrusion.

Grade 2: medium–size annulus protrusion obliterating two thirds of the anterior epidural and subarachnoid spaces.

Grade 3: large disc protrusion dislocating the spinal cord posteriorly.

Grade 4: large disc protrusions compressing the spinal cord.
