Spondylolisthesis

Spondylolisthesis is Latin for “slipped vertebral body,” and it is diagnosed when one vertebra slips forward over the one below it. This condition occurs as a consequence of the general aging process in which the bones, joints, and ligaments in the spine become weak and less able to hold the spinal column in alignment, but may also be caused by stress fractures, or congenital abnormalities, and in rare cases from a tumor or trauma.
