About The Sarah Key Physiotherapy Centre

Each segment of the spine is made up of the intervertebral disc in the front compartment and a pair of facet joints in the back. Both mechanisms operate as a sort of hinge to give the segment mobility yet stability, and they work in very different ways. The additional specific functions of disc and facet means they suffer very different strains and a segment becomes painful when either [or both] mechanism malfunctions. Wear and tear of either structure manifests as its own idiosyncratic type of back pain.
