Grace Walker, physical and occupational therapist and nutrition, asks what do you know about intervertebral discs? You probably do know that they are commonly associated with words like pain or discomfort. Perhaps you’ve heard some say “I’ve ‘slipped’ a disc in my back”. Many people believe that discs are fragile, but how much truth is there to that? Keep reading and you may be surprised!
If you’ve read the title, and you suffer from back pain, you might have done a double-take. The point is– discs don’t simply “slip” out of place. If you have the picture in your head that discs slip like a bar of soap in the shower, you’ve got the wrong idea.
What is the function of the disc?
Every segment of your spine has discs, except for the last few vertebrae in the top of your cervical (neck) spine. Discs are composed of several layers of cartilage that surround an inner gel-like center material, called the nucleus pulposus. The end plate which connects to the actual vertebrae is both bony and cartilaginous, and creates an exceptionally strong connection. This makes it IMPOSSIBLE for discs to ‘slip’. They do not slip out of place like a banana peel! The nucleus pulposus, can however ooze out and press on a nerve root. This is called a protrusion. This protrusion can break of and become a herniation.
Can discs become injured?
Yes. Can discs heal? Yes. Are they strong? More than you know! A study examined the results of strength tests in both younger and older populations. They found it takes 740 lbs. of force to compress the disc height 1mm in young subjects and 460 lbs. in older patients. Ultimately, it was concluded that the discs are VERY strong. However, we know that shearing forces, that might be experienced while lifting and twisting, or blunt force trauma, from things such as car accidents, are much more likely to injure discs.
