Spondylolisthesis is a slippage of vertebral bodies out of their normal position, usually a forward slippage of the 5th lumbar vertebra over the 1st sacral vertebra (L5-S1). More rarely, a type of spondylolisthesis called retrolisthesis involving the backward displacement of a vertebral body occurs. Most spondylolisthesis is seen in the lumbar spine (L1-L5/S1). This disorder can been seen on plain X-rays. It is significantly more likely to be seen on X-rays taken in the standing position than in those taken in lying position—with weight on the spine, slippage is more likely.
However, severe or even significant neurological abnormalities (sensory changes, reflex changes, muscle weakness or atrophy) are not to be expected in spondylolisthesis
Studies have shown that most individuals with spondylolisthesis, lead active lives with little, if any, adjustment for having this type of spinal abnormality. Spondylolisthesis is most likely to become limiting as a contributing factor for spinal stenosis in combination with other spinal disorders, such as severe osteoarthritis and severely bulging intervertebral discs.
