Lumbar Spine Instability
What is lumbar spine instability?
The lumbar spine consists of 5 bones (vertebrae) at the bottom end of the spine. Those 5 bones interact with each other via a total of 30 individual joints, have countless ligaments attaching to them, and also have up to 10 different spinal muscle groups that contribute to their movement.
The lower back is affected by the movement of the thoracic spine above, and the tailbone (sacro-iliac joint) below.
If these ligaments are loose or the muscles around the spine are not strong enough or don’t work properly, the spine can become unstable.
