Intervertebral disc degeneration of cervical spine without prolapsed disc

Definition

The diagnosis of herniation is usually made by observation of displacement of disk material beyond the edges of the ring apophyses that is localized, meaning less than 50% (180°) of the circumference of the disk. Localized displacement in the axial (horizontal) plane can be focal, signifying less than 25% of the disk circumference, or broad based, meaning between 25% and 50% of the disk circumference. Presence of disk tissue circumferentially (50%–100%) beyond the edges of the ring apophyses may be called bulging and is not considered a form of herniation.
