Okano I, Jones C, Salzmann SN, et al. - Researchers applied site-specific, endplate volumetric BMD (EP-vBMD) as a potential predictive marker of severe cage subsidence in standalone lateral lumbar interbody fusion (SA-LLIF) individuals and carried out a retrospective comparative study between EP-vBMD and trabecular vBMDs (Tb-vBMD) in the vertebrae. Between 2007 and 2016, individuals undergoing SA-LLIF were retrospectively analyzed. This study correlated Tb-vBMDs and EP-vBMDs between disk levels that had severe cage subsidence and levels with no severe subsidence. A novel site-specific vBMD measurement was introduced for cage subsidence risk assessment. The outcomes of this study indicated that EP-vBMD was a reproducible measurement and seemed more predictive for severe cage subsidence after SA-LLIF than Tb-vBMD.
