Abstract

OBJECTIVE: Preserving the ligamentum flavum (LF) during lumbar spine surgery can help to limit the extent of postoperative epidural fibrosis (EF), which is a potential cause of persistent leg pain. We present a retrospective analysis of microdiscectomy with preservation of the LF to evaluate the effects of the two LF mobilizing techniques (reflecting inferiorly or medially vs. removing completely) on EF and clinical outcomes.
