Defining motion segment instability has not always been possible with conventional dynamic radiographs and measuring techniques. It is known that the biomechanical stress on the vertebral bodies which is associated with degenerative disk disease can cause a variety of pathological changes in the marrow. Therefore, we used magnetic resonance (MR) to detect focal alterations in bone marrow signal intensity adjacent to the end-plates in patients with degenerative disks to assess segmental spinal instability.
