4 Stages of Spinal Disc Injury

The most common injury we care for are spinal disc injuries.  Most of the time they can fall into 4 Stages of Spinal Disc Injury.


  1. The Degenerative disc.  This is a disc that has lost much of its volume and often times “slacks” on to the spinal or spinal nerves.  This condition could develop from a previous injury (usually years earlier), from someone who has been very active their entire life or as the result of repeated stresses that wears the disc down.  It generally occurs in people over the age of 40 and most of the time over the age of 60.
  2. The Prolapse disc or “bulging disc” is a disc injury that does not tear or rip the outer layer of the disc (correctly called the annulus fibrosus.  This is the part that holds the entire disc together which is a tougher circular exterior.  When this injury occurs the disc becomes something similar to an “air bubble” in a tire; where the annulus fibrosis bulges putting pressure on nerves.
  3. The Extruded disc (also called slipped disc) is when the outer layer actually tears.  The inner core (nucleus pulposus) actually penetrates through the annulus fibrosis exiting the disc.  In this condition not only do the outer layers need to heal but the exiting core needs to be put back in the middle.
  4. The Sequestration disc is when a piece of the extruded nucleus pulposus tears and can float around the spinal column.  Generally surgical intervention is needed to remove the tore part as it can land on nerves creating severe pain.
