What causes back pain? Spinal Disc Anatomy Expert Explains


The disks are a unique structure because
they’re the largest avascular structures in the body so it sets up a
stage where if there is injury within the disc, it’s tough to repair and the
disk is only innervated when it’s healthy on the outer periphery so if you
have an injury within the disc that’s deep, often you don’t even feel it.
Especially if it’s a healthy disc and later in time when the fissure
starts to separate or to open – it’s called delamination – then the whole
disc will get compressed very similar to a car tire. It
will bulge if the disc loses too much of its integrity or its pressure, it’s
almost like the rims of the vertebra will touch and they’re
very pain sensitive too. We’re learning now that a lot of the spine problems are
due to discs that are a little bit slippery or they don’t hold their
stiffness just like a car tire you know when you’re when your car tire’s a little
low, the car will not perform and it’ll kind of move in ways that is a
little bit unpredictable and that’s what we’re seeing with the spine now, which is
quite interesting. So when you decompress there is a lengthening of the spine
and the discs gain some height, creating more room for the nerves that exit out
through these canals. In doing so there’s a negative pressure that’s
elicited within these disks and the nutrients get drawn from the vertebrae
primarily into the disc to raise the disc height. So drawing in nutrients
to these cells allows these cells to heal very likely more effectively
because it’s a very desolate landscape with very little
oxygen and glucose so if you can draw in these nutrients, then these cells become
more active and can metabolize and help heal up the injured structures. By
doing so with a greater disc height you’ve got more room for the nerves,
there’s less compression with the facet joints and the spine is just much
happier. you you
