Lumbar Spine Endplate Sclerosis is a Protective Factor for Cage Subsidence in Minimally Invasive Transforaminal Lumbar Interbody Fusion.

ABSTRACT: Study designRetrospective single-center cohort study.ObjectiveTo investigate the predictive value of preoperative endplate Hounsfield unit (HU) measurements for cage subsidence (CS) following minimally invasive transforaminal lumbar interbody fusion (MI-TLIF), and to propose threshold values for risk stratification.MethodsA total of 169 patients undergoing one- and two-level MI-TLIF with preoperative lumbar CT imaging were included. Endplate HU values were quantified within a 5-mm region of interest at the cage-endplate interface. Mild and severe CS was defined as 2-4 mm and ≥4 mm migration of the interbody cage into the adjacent vertebral endplate. Logistic regression analyses were employed to identify risk factors for CS.ResultsCS occurred in 39 of 464 endplates. Significantly lower L1 v
