Is an increase in height of spinous process associated with decreased heights of intervertebral disc and vertebral body in the degenerative process of lumbar spine?
Changes in the spinous process morphology followed degenerative changes of the intervertebral disc and vertebral body in the degenerative process of the lumbar spine. This result may suggest that the morphological change of an increase in the height of the spinous process may be a kind of biological defense reaction to stabilize the intervertebral portion.
The limitation of the study was retrospective design.
