An Institutional Six-year Trend Analysis of the Neurological Outcome After Lateral Lumbar Interbody Fusion

Abstract

To the authors' best knowledge, this study constitutes the largest series of this sort to date, with regard to both sample size and study period. The present data indicate a decreasing proportional trend over time for SDs, MDs, and anterior TP, which can be considered a representation of an institutional learning curve during a 6-year time period of performing LLIF.
