Spondylolisthesis occurs when one segment of the naturally aligned spine slides forward, backward, or sideways on the other. The incidence of lumbar spondylolisthesis is 6% in adulthood, and it is most commonly seen in the lumbosacral region and mid-lumbar region, and it can be seen rarely in the cervical and thoracic regions. Meyerding's grading system is used to determine the degree of slip in spondylolisthesis. Wiltse Newman classification based on etiology and anatomy and Marchetti and Bartolozzi classification based on etiology is still the most widely used classification today. Spinal Deformity Study Group Classification is another widely used classification system by evaluating the degree of slippage and spinopelvic balance.
