Mid-lumbar traumatic spondyloptosis without neurological deficit: A case report and literature review.

Medicine (Baltimore) 2020 Mar;99(12):e19578

Department of Spine Surgery, The First Hospital of Jilin University.

Introduction: Spondyloptosis is a form of vertebral dislocation and the most advanced form of spondylolisthesis. Traumatic spondyloptosis is usually caused by high-energy impact and results in unstable spine deformity and spinal canal deformation, which lead to severe spinal cord injury. Traumatic spondyloptosis is mostly reported in the lumbo-sacral junction, while it is rarely documented in mid-lumbar segments. Read More

Successful Bony Healing For An Adult Patient With Isthmic Spondylolysis At Terminal Stage After Conservative Treatment: A Case Report.

J Pain Res 2019 5;12:3257-3261. Epub 2019 Dec 5.

Department of Orthopedic Surgery, The First Affiliated Hospital of Wenzhou Medical University, Wenzhou, Zhejiang, People's Republic of China.

Purpose: Spondylolysis, a defect or fracture of the pars interarticularis due to mechanical stress, is a common cause of lower back pain (LBP) in children and adolescents. Although conservative treatment has been shown to be most effective for young patients at early or progressive stage, few studies have reported the outcomes of conservative treatment for adult spondylolysis at terminal stage. We present the possibility of bony healing in the isthmic defect at terminal stage after conservative treatment. Read More

Evaluating low back pain in adolescents.

JAAPA 2019 Dec;32(12):14-20

Sarah J. Garvick is associate program director of the PA program at the Boone, N.C., campus of Wake Forest School of Medicine. Candice Creecy, Megan Miller, Lorae Schafer, Alex Spooner, and Ann Wallace Tazewell were students in the PA program at Wake Forest School of Medicine in Winston-Salem, N.C., when this article was written. Tanya Gregory is an assistant professor and director of student services in the PA program at Wake Forest School of Medicine in Winston-Salem. The authors have disclosed no potential conflicts of interest, financial or otherwise.

Low back pain in adolescents is a common complaint in primary care. With an average prevalence rate of 40%, adolescent low back pain correlates with greater healthcare use, higher incidences of adult back pain, and negative effects on overall well-being. A thorough history and physical examination can increase early detection and accurate diagnosis while ensuring the judicious use of diagnostic modalities. Read More

The correlation between sagittal spinopelvic alignment and degree of lumbar degenerative spondylolisthesis.

J Orthop Sci 2019 Nov 21;24(6):969-973. Epub 2019 Sep 21.

Department of Orthopedic Surgery, Integrated Health Sciences, Institute of Biomedical & Health Sciences, Hiroshima University, Kasumi 1-2-3, Minami-ku, Hiroshima, 734-8551, Japan.

Background: Recently, several authors reported that a high pelvic incidence (PI) might be a predisposing factor to the development of anterior slip in the vertebral body in degenerative spondylolisthesis (DS). The purpose of this study was to analyze patients with DS using a multiple linear regression model, in terms of the correlation between the sagittal spinopelvic parameters and the severity of slip in each lumbar spine, including both anterior and posterior directions.

Methods: Standing lateral radiographs were taken of 104 patients (59 women and 45 men) with lower back pain. Read More

Pseudohypoxic Brain Swelling After Uncomplicated Lumbar Decompression and Fusion for Spondylolisthesis.

World Neurosurg 2020 Jan 4;133:155-158. Epub 2019 Sep 4.

Department of Neurological Surgery, Loyola University Medical Center, Maywood, Illinois, USA. Electronic address:

Background: Pseudohypoxic brain swelling (PHBS), also known as postoperative intracranial hypotension-associated venous congestion, is a rare complication after neurosurgery characterized by rapid and often severe postoperative deterioration in consciousness and distinct imaging findings on brain magnetic resonance imaging. Imaging findings associated with PHBS include computed tomography and magnetic resonance imaging findings that resemble hypoxic changes and intracranial hypotensive changes in basal ganglia and thalamus, telencephalic, and infratentorial regions without notable changes in intracranial vasculature.

Case Description: This report describes the case of an L4-5 microdiskectomy with posterior decompression and fusion complicated by clinical and radiographic findings resembling PHBS without a known intraoperative durotomy. Read More

Three-Dimensional Planning and Patient-Specific Drill Guides for Repair of Spondylolysis/L5 Pars Defect.

World Neurosurg 2019 Dec 27;132:75-80. Epub 2019 Aug 27.

Medacta International SA, Castel San Petro, Switzerland.

Background: Incomplete ossification of the pars interarticularis will result in a pars defect, a common cause of low back pain in youth and strongly associated with participation in high-impact sports. If left untreated, it can result in spondylolisthesis, causing dynamic canal stenosis, low back pain, and radiculopathy. The treatment of pars defect was first described by Bucks in 1970, who used screws in the lamina placed through an upward and outward direction. Read More

The pathogenesis and clinical results of symptomatic lower lumbar OVFs have not been analysed. We aimed to retrospectively investigate the risk factors for the occurrence of neurological symptoms in patients with lower lumbar OVFs and to assess the clinical results of these symptoms using magnetic resonance (MR) images.

The correlation analysis between sagittal alignment and cross-sectional area of paraspinal muscle in patients with lumbar spinal stenosis and degenerative spondylolisthesis.

BMC Musculoskelet Disord 2019 Jul 31;20(1):352. Epub 2019 Jul 31.

Department of Orthopaedic Surgery, Tokai University School of Medicine, 143 Shimokasuya, Isehara, Kanagawa, 259-1193, Japan.

Background: The relationship between spinal alignment and skeletal muscle mass (SMM) has attracted attention in recent years. Sagittal alignment is known to deteriorate with age, but it is not known whether this is related to paraspinal muscles. Therefore, the purpose of this study is to elucidate the role of the multifidus (MF) and psoas major (PS) muscles in maintaining global spinal alignment in patients with lumbar spinal stenosis (LSS) and/or degenerative spondylolisthesis (DS), and to analyze whether each muscles' cross-sectional area (CSA) correlates with whole-body SMM using bioimpedance analysis (BIA).

Spinopelvic parameters in degenerative spondylolisthesis.

Acta Orthop Belg 2019 Jun;85(2):253-259

The purpose of this study was to compare various sagittal spinopelvic parameters between patients with and without degenerative lumbar spondylolisthesis (DLS). A total of 165 patients who underwent surgery for low back and/or radicular pain were divided into two groups: those without DLS (non-DLS group; n = 85) and those with DLS (DLS group; n = 80). In all sagittal spinopelvic parameters, no significant difference was found between the non-DLS and DLS groups. Read More

JBJS Case Connect 2019 Apr-Jun;9(2):e0039

IRCCS Istituto Ortopedico Rizzoli, Bologna, Italy.

Case: A 64-year-old woman with a history of low back pain, presented with acute gait impairment and lower limbs numbness without any history of trauma. Imaging studies revealed ossification of the ligamentum flavum (OLF) at L4-L5 and concomitant spondylolisthesis. Decompression surgery with en-bloc removal including the laminae, the ossified ligamentum flavum, and the medial facet and posterior stabilization was performed resulting in complete immediate recovery.

[Lumbar synovial cysts: literature review and original long-term results after microsurgical resection].

Orthopade 2019 Oct;48(10):849-857

Wirbelsäulenorthopädie und Rekonstruktive Orthopädie, Sana Klinikum Offenbach, Offenbach, Deutschland.

Background: Intraspinal lumbar vertebral joint cysts are an unusual cause of nerve root compression symptoms and do not differ clinically from the symptoms of a herniated disc.

Pathogenesis: The cysts originate from the small vertebral joints and, depending on their size, compress the nerval structures. The affected vertebral joints typically show activated arthritic circumstances, which are associated with degenerative spondylolisthesis in about 50% of cases. Read More
