Lumbar Ligamentum Flavum: Spatial Relationships to Surrounding Anatomical Structures and Technical Description of En Bloc Resection

Abstract

Our cadaveric and microscopic surgical dissections show the ligamentum flavum as seen in the new corridors of small surgical exposures during minimally invasive surgeries of the lumbar spine. Identifying this landmark, surgeons can envision the location of the nerve roots to help prevent their injury.
