In lateral plating following XLIF, repositioning time is zero, as the XLIF exposure is used for placement. Lateral plating also accounts for short second-procedure times in the range. Longer second-procedure times include, in some cases, posterior lumbar interbody fusion at L5–S1 and multilevel posterior fixation, which accounts for the high variability.
