Less Exposure Segmental Spine (LESS) Surgery for L4-5 Degenrative Spondylolisthesis through a 2 inch incision with minimal blood loss. The unstable and painful spine was stabilized with FacetFuse Transfacet Pedicle Screws, InSpan Interspinous Plate Fixation, TLIFT PEEK Interbody, DBMPure bone graft in the interbody space and facets. The technologies used were all from SpineFrontier Inc. The LES philosophy teaches us to preserve the facets, spinous processes, and the multifidus attachments and integrity with minimal muscle retraction and short surgery time. We directly visulaize and decompress the nerves with less radiation exposure to the patient from use of fluoroscopy as is needed in fusion that use minimally invasive spine surgery (MISS) using percutaneous cannulas/retractor tubes to take out the facet to place a TLIF cage.
