What Is Segmental Spinal Instability? | Minneapolis Spine Surgeon
WebSegmental spinal instability is a condition characterized by an excessive range of motion between two vertebral segments in the spinal column. This increased range of motion is known as hypermobility, and it often develops when a spinal disc or facet joint erodes to the point where it can no longer support the weight of the body through that ...
WebWithin lumbar instability, we distinguish functional (clinical) instability and structural (radiografic) instability. Functional instability, which can cause pain despite the absence of any radiological anomaly, can be defined as the loss of neuromotor capability to control segmental movement during mid-range.
