What range does Grade IV spondylolisthesis translation fall into in Meyerding classifications?

Explanation:
Meyerding classification assesses how far the upper vertebra has slipped forward over the one below, expressed as a percentage of the width of the lower vertebral body. Grade IV means the slip is between 76% and 100%, indicating a severe but not complete dislocation. This places it above the 51-75% range of Grade III and below the greater-than-100% category of Grade V (spondyloptosis). So the correct range for Grade IV is 76-100% slip.
