Postoperative Delirium After OLIF-PPSF Versus TLIF: A Propensity Score-Matched Analysis over 16 Years

Background/Objectives: Postoperative delirium is a clinically important complication after lumbar fusion surgery, yet whether the choice of fusion technique influences its occurrence remains unclear. We compared the incidence of postoperative delirium between oblique lateral interbody fusion with percutaneous pedicle screw fixation (OLIF-PPSF) and transforaminal lumbar interbody fusion (TLIF).
