Flexion-extension standing radiographs underestimate instability in patients with single-level lumbar spondylolisthesis: comparing flexion-supine imaging may be more appropriate.

J Spine Surg 2021 Mar;7(1):48-54

Department of Orthopaedics, Columbia University Medical Center, The Spine Hospital at New York-Presbyterian, New York, NY, USA.

Background: Generally, most spine surgeons agree that increased segmental motion viewed on flexion-extension radiographs is a reliable predictor of instability; however, these views can be limited in several ways and may underestimate the instability at a given lumbar segment.

Methods: Consecutively collected adult (≥18 years old) patients with symptomatic single-level lumbar spondylolisthesis were reviewed from a two-surgeon database from 2015 to 2019. Routine standing lumbar X-rays (neutral, flexion, extension) and supine lumbar MRI (sagittal T2-weighted imaging sequence) were performed. Read More

Asian J Neurosurg 2020 Oct-Dec;15(4):1059-1067. Epub 2020 Oct 19.

Department of Radiology, Bumrungrad International Hospital, Bangkok, Thailand.

The authors describe two cases harboring lumbosacral spinal dural arteriovenous fistulas (SDAVFs) manifested with nonspecific initial symptoms, leading to misdiagnosis and unnecessary procedures.

Endplate injury as a risk factor for cage retropulsion following transforaminal lumbar interbody fusion: An analysis of 1052 cases.

Medicine (Baltimore) 2021 Feb;100(5):e24005

Department of Orthopaedic Surgery, Sir Run Run Shaw Hospital, School of Medicine, Zhejiang University.

Magnetic resonance imaging findings of redundant nerve roots of the cauda equina.

World J Radiol 2021 Jan;13(1):29-39

Department of Radiology, Tokat Gaziosmanpasa University, Faculty of Medicine, Tokat 60100, Turkey.

Background: Redundant nerve roots (RNRs) of the cauda equina are often a natural evolutionary part of lumbar spinal canal stenosis secondary to degenerative processes characterized by elongated, enlarged, and tortuous nerve roots in the superior and/or inferior of the stenotic segment. Although magnetic resonance imaging (MRI) findings have been defined more frequently in recent years, this condition has been relatively under-recognized in radiological practice. In this study, lumbar MRI findings of RNRs of the cauda equina were evaluated in spinal stenosis patients. Read More

Eur Radiol 2021 Jan 14. Epub 2021 Jan 14.

Department of Diagnostic and Interventional Radiology, Klinikum rechts der Isar, School of Medicine, Technical University of Munich, Munich, Germany.

Objectives: To evaluate the performance of 3D T1w spoiled gradient-echo (T1SGRE) and ultra-short echo time (UTE) MRI sequences for the detection and assessment of vertebral fractures and degenerative bone changes compared with conventional CT.

Modifications in lumbar facet joint are associated with spondylolisthesis in the degenerative spine diseases: a comparative analysis.

Acta Neurochir (Wien) 2021 03 6;163(3):863-871. Epub 2021 Jan 6.

Department of Surgery, Section of Neurosurgery, Aga Khan University Hospital, Stadium Road, Karachi, Sindh, 74800, Pakistan.

Background: Magnetic resonance imaging (MRI) is important in the assessment of degenerative spine disease. However, its role is limited in the identification of spinal instability; therefore, weight-bearing and dynamic studies like X-rays are required. The supine position eliminates the gravitational pull, corrects the vertebral slippage, and opens the facet joints leading to the collection of the synovial fluid into the joint space, which is detected on the MRI and can serve as a marker for instability.

J Clin Immunol 2021 Apr 6;41(3):576-584. Epub 2021 Jan 6.

Center for Infectious Disease Imaging, Radiology and Imaging Sciences, Clinical Center, National Institutes of Health, Bethesda, MD, USA.

Loss of function mutations in STAT3 (STAT3-LOF; autosomal dominant hyper-IgE (Job's) syndrome) are associated with a variety of musculoskeletal manifestations, including scoliosis, osteoporosis, and minimal trauma fractures. This retrospective magnetic resonance (MR) imaging study sought to characterize an unusual pattern of cervical spine degeneration among a cohort of STAT3-LOF patients. Cervical spine MR images of the STAT3-LOF cohort (n = 38) were assessed for a variety of degenerative changes and compared to age-matched groups of controls (n = 42) without known immune or musculoskeletal abnormalities.

Minimally Invasive Treatment for Degenerative Lumbar Spine.

Tech Vasc Interv Radiol 2020 Dec 5;23(4):100700. Epub 2020 Oct 5.

Neuroradiology and Pain Solutions of Oklahoma, Oklahoma City, OK. Electronic address:

Degenerative lumbar spine disorder (DLSD) is a ubiquitously occurring event that may be induced or accelerated by multiple factors such as from overuse, trauma, genetic predisposition, nutrition deficiency, and others. While our understanding of this degenerative disorder is limited, in terms of prevention, the symptoms from DLSD can be significant and may lead to the reduction in the patient's quality of life and loss of work time. In the Global Burden of Disease Study, low back pain was ranked the highest of 291 different conditions, due to the number of years lost to disability, amounting to 83 million disability-adjusted life years lost in 2010.
