Spondylolisthesis is a condition, in which one vertebral body slips with respect to an adjacent vertebral body. Radiographs
are the standard diagnostic modality for its diagnosis. Loss of alignment of one vertebral body to the next is the diagnostic
hallmark. Radiographs have a larger role to play apart from diagnosis, as the classification and grading of spondylolisthesis
are based on radiographs. We demonstrate the complete radiological analysis of spondylolisthesis including the description of
method of drawing the several parameters, and their significance. We provide a pictorial representation of the assessment of
Meyerding’s grading by measurement of slip, slip angle/kyphotic angle, sacral slope, pelvic tilt, and pelvic incidence on digital
radiographs.
