Disk Disease A: breakdown of the annulus (Herniation) n B: nucleus pressing against outer annulus (Protrusion) Protrusion= n C: extrusion of nuclear material, but still in contact with the disk (Extrusion) n D: free sequestration of the nuclear material (nuclear material has separated from the disk) n
