What is spinal instability?

Increased mobility between one vertebra and another

Back and leg aches may also be caused by spinal instability, which may be caused by degeneration of the intervertebral disc, degeneration of the facet joints between the vertebrae and thickening of the bands of connective tissue between the vertebral arches. This causes a narrowing of the spinal canal and increased mobility between one vertebra and its neighbour, which in turn may cause a vertebra to be displaced. Depending on the severity of their symptoms, patients may or may not benefit from surgery.
