Fine versus Sclerotic Trabecular Bone Remodeling/Restructure: A Refined Radiographic Predictor for Long-Term Segment Stability After Posterior Lumbar Interbody Fusion.

ABSTRACT: Study DesignRetrospective cohort study.ObjectivesSuccessful bone fusion is crucial for favorable posterior lumbar interbody fusion (PLIF) outcomes. While trabecular bone remodeling (TBR) indicates osseointegration, its interpretation remains uncertain. This study aimed to clarify the clinical significance of distinct TBR types-fine TBR (fTBR) and sclerotic TBR (sTBR)-as seen on computed tomography (CT) scans and to evaluate their predictive value for segment stabilization and complete bone fusion and their relationship with interbody cage materials.MethodsSeventy-one patients who underwent one-level PLIF with follow-up exceeding 5 years were included. Interbody cages were made of carbon fiber-reinforced polymer (CFRP; 37 segments) or titanium-coated polyether-ether-ketone (TiPEEK; 34 segme
