High Sacral Endplate Inclination Vector Forces Are Associated with Pars Fracture-Mediated Lumbosacral Spondylolisthesis.

World Neurosurg 2019 Feb 1;122:e790-e794. Epub 2018 Nov 1.

Department of Neurosurgery, Harvard Medical School, Boston, Massachusetts, USA. Electronic address:

Objective: Lumbar spondylolisthesis can be related to facet arthropathy and disc degeneration or to a fracture of the pars interarticularis, but the mechanistic underpinnings of spondylolisthesis remain unclear. We posit that high sacral slope and body weight increase sacral inclination vector forces, which leads to pars fractures and exacerbates risk for spondylolisthesis.

Methods: To investigate this hypothesis, we measured the sacral slope, body weight, and S1 endplate vector forces for patients who underwent L5-S1 fusion for grade I spondylolisthesis. Read More

Department of Orthopaedic Surgery, University of Minnesota, 2450 Riverside Avenue South, Suite R200, Minneapolis, MN 55454, USA; Department of Neurosurgery, University of Minnesota, 2450 Riverside Avenue South, Suite R200, Minneapolis, MN 55454, USA. Electronic address:

High-grade dysplastic spondylolisthesis (HGDS) is a subset of L5-S1 spondylolisthesis that occurs due to dysmorphic anatomy at the lumbosacral junction, often resulting in sagittal imbalance. Enhanced understanding of global sagittal alignment has led many to preferentially treat HGDS with reduction and fusion to restore sagittal balance. The purpose of this article is to review published surgical techniques for obtaining sagittal correction in HGDS and to evaluate the current evidence regarding the associated surgical complications.

Sagittal Alignment of the Lumbar Spine.

Neurosurg Clin N Am 2018 Jul;29(3):331-339

Neurosurgery, UCSF Spine Center, 400 Parnassus Avenue, San Francisco, CA 94143, USA. Electronic address:

Alignment of the lumbar spine has an important impact on the segmental motion, degenerative pathology, and health-related quality of life. The relationship between lumbar lordosis and pelvic incidence is predictive in the pathogenesis of spinal disorders, including disk degeneration, spondylolisthesis, and adjacent segment degeneration. This article reviews the relationship between lumbar and pelvic alignment with pathology of the lumbar spine, provides goals for appropriate alignment in reconstructive surgery, and discusses strategies for effective realignment of the spine.

Mild (not severe) disc degeneration is implicated in the progression of bilateral L5 spondylolysis to spondylolisthesis.

BMC Musculoskelet Disord 2018 04 2;19(1):98. Epub 2018 Apr 2.

Spine Service, Department of Orthopaedic Surgery, St. George & Sutherland Clinical School, University of New South Wales Australia, Kogarah, Sydney, NSW, 2217, Australia.

Background: Spondylolytic (or lytic) spondylolisthesis is often associated with disc degeneration at the index-level; however, it is not clear if disc degeneration is the cause or the consequence of lytic spondylolisthesis. The main objective of this computed tomography based finite element modelling study was to examine the role of different grades of disc degeneration in the progression of a bilateral L5-lytic defect to spondylolisthesis.

Methods: High-resolution computed tomography data of the lumbosacral spine from an anonymised healthy male subject (26 years old) were segmented to build a 3D-computational model of an INTACT L1-S1 spine. Read More

Biomechanical comparison of transdiscal fixation and posterior fixation with and without transforaminal lumbar interbody fusion in the treatment of L5-S1 lumbosacral joint.

Proc Inst Mech Eng H 2018 Apr 23;232(4):371-377. Epub 2018 Feb 23.

4 Department of Mechanical Engineering, TOBB University of Economics and Technology, Ankara, Turkey.

Transdiscal screw fixation is generally performed in the treatment of high-grade L5-S1 spondylolisthesis. The main thought of the study is that the biomechanical performances of the transdiscal pedicle screw fixation can be identical to standard posterior pedicle screw fixations with or without transforaminal lumbar interbody fusion cage insertion. Lumbosacral portions and pelvises of 45 healthy lambs' vertebrae were dissected. Read More

The safe use of long screws in L5/S1 stand-alone anterior interbody fusion for olisthesis cases.

Br J Neurosurg 2018 Feb 6;32(1):28-31. Epub 2018 Feb 6.

a The Centre for Spinal Studies and Surgery , Queens Medical Centre, Nottingham University Hospitals NHS Trust , Nottingham , UK.

Background: Stand-alone anterior interbody fusion (STALIF) with poly-ether-ether-ketone (PEEK) cages could offer a treatment option in olisthesis cases. The fixation of the PEEK-cage at the L5/S1 inferior endplate with long divergent screws however might endanger neural sacral structures, especially the S1 nerve root. If shorter screws are used, the achieved bony purchase might not be sufficient to resist the pull out and shear forces at the lumbosacral junction. Read More
