About this study

This is a prospective single-center study. Patients requiring posterior lumbar interbody fusion (PLIF) for lumbar degenerative disease are prospectively enrolled and followed. Important adjacent pre-existing degeneration factors include discs degenerated, facets and ligamentum flavum tropism which could lead to spinal canal stenosis (SCS). This study will focus on the effects of pre- existing adjacent degeneration (disc factors and spinal canal stenosis factors) on long-term postoperative outcomes.
