Patient and radiographer assessment of slump sitting flexion compared to conventional standing forward bending flexion.

J Spine Surg 2018 Dec;4(4):750-756

University Orthopaedics, Hand and Reconstructive Microsurgery Cluster (UOHC), National University Health System, Singapore, Singapore.

Background: A comparative survey from patients and radiographers of the new slump sitting flexion posture and the conventional standing forward bending posture. This study was performed to compare the technical and logistical aspects of the slump sitting versus the forward bending posture. Slump sitting flexes the lumbar spine more than the forward bending and increases the diagnosis rate of sagittal spinal instability up to 40% depending on the diagnostic criteria used. Read More

Identification of abnormalities in the lumbar nerve tract using diffusion-weighted magnetic resonance neurography.

Eur Spine J 2019 Jan 17. Epub 2019 Jan 17.

Department of Orthopedics, Institute of Biomedical Sciences, Tokushima University Graduate School, 3-18-15 Kuramoto-cho, Tokushima, 770-8503, Japan.

Introduction: Abnormalities of the lumbar nerve tract caused by congenital variations or high nerve root take-off angles are difficult to visualize. Diffusion-weighted magnetic resonance neurography (DW-MRN) has recently been introduced for imaging of the lumbosacral region. The aims of this study were to identify lumbar nerve tract abnormalities caused by congenital variation or a high nerve root take-off angle using DW-MRN and to assess the diagnostic value of this imaging modality.

Degenerative Lumbar Spondylolisthesis: Biochemical Aspects and Evaluation of Stabilization Surgery Extent in Terms of Adjacent Segment Disease Theory.

World Neurosurg 2019 Jan 29;121:e554-e565. Epub 2018 Sep 29.

Department of Pharmacology, Jessenius Faculty of Medicine, Comenius University, Martin, Slovakia.

Objective: In lumbar degenerative spondylolisthesis (DSL), the criteria and extent of surgical treatment have not been strictly defined owing to the adjacent segment disease theory and unclear molecular pathogenesis. The present study analyzed the clinical and radiographic findings of patients after lower lumbar fusion surgery with single and 2-level DSL and explored the inflammatory mediator's role in DSL evolution and symptoms.

Methods: The prospective follow-up of patients with DSL, stratified by the stabilization extent (L4-L5, L5-S1, and L4-S1), included the Back Illness Pain and Disability 9-item questionnaire and native and dynamic radiographs to evaluate the intervertebral disc height and adjacent segments' angular motion.

Transfacet Screw Fixation for the Treatment of Lumbar Spinal Stenosis with Mild Instability: A Preliminary Study.

J Neurol Surg A Cent Eur Neurosurg 2018 Sep 16;79(5):358-364. Epub 2018 Jul 16.

NESMOS Department, Sapienza University of Rome, Rome, Italy.

Background:  Lumbar spinal stenosis (LSS) and low-grade degenerative spondylolisthesis are frequently associated with facet joint degeneration, considered the main cause of low back pain. Surgery is the treatment of choice in patients affected by LSS unresponsive to conservative treatment.

Sacropelvic Fixation: When, Why, How?

Neurosurg Clin N Am 2018 Jul;29(3):389-397

Department of Orthopaedic Surgery, Columbia University Medical Center, The Spine Hospital at New York Presbyterian, 5141 Broadway, 3 Field West, New York, NY 10034, USA.

The indications for sacropelvic fixation continue to evolve with emerging instrumentation technologies and advancing techniques. Common indications include long construct fusions, high-grade spondylolisthesis, sacral fractures, sacral tumors, and global sagittal and/or coronal imbalance among others. The authors' preferred technique is through use of a freehand S2-alar-iliac screw placement. Read More

The Challenge of Creating Lordosis in High-Grade Dysplastic Spondylolisthesis.

Neurosurg Clin N Am 2018 Jul;29(3):375-387

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.

Radiological and Clinical Comparison of Posterolateral Fusion and Transforaminal Interbody Fusion Techniques in Degenerative Lumbar Stenosis.

World Neurosurg 2018 Aug 1;116:e1060-e1065. Epub 2018 Jun 1.

Department of Neurosurgery, Health Sciences University, Diskapi Yildirim Beyazit Education and Research Hospital, Ankara, Turkey.
