Department of Neurosurgery, Faculty of Medicine, Jordan University of Science and Technology (JUST), Irbid 22110, Jordan.

Background: Spine-related pain is a complex heterogeneous condition. Excessive reliance on radiological imaging might lead to overdiagnosis of incidental asymptomatic spinal changes and unnecessary surgery. Approaches to the clinical management of spine pain should (1) identify pain generators, types, patterns, and mechanisms; (2) confirm clinical suspension with a diagnostic injection; and (3) ensure that treatment is aimed at controlling pain and improving patient function rather than image-based surgical success.

The Clinical Usefulness of Preoperative Imaging Studies to Select Pathologic Level in Cervical Spondylotic Myelopathy: Comparative Analysis of Three-Position MRI and Post-Myelographic CT.

Turk Neurosurg 2019 ;29(1):127-133

The Catholic University of Korea, College of Medicine, Seoul St. Mary's Hospital, Department of Neurosurgery, Seoul, Korea.

Aim: To compare the accuracy of determining pathologic segment between three-position MRI (3P-MRI) and post-myelographic CT (PMCT) in cervical spondylotic myelopathy (CSM) by assessing the degree of inter-observer and intra-observer agreement.

Material And Methods: We retrospectively reviewed 3P-MRI and PMCT for the diagnosis of multilevel CSM in 136 patients who underwent surgery. Using an assessment scale, 8 blind observers with various clinical experiences examined 5 parameters: spinal canal narrowing, foraminal stenosis, bony abnormality, intervertebral disc herniation, and nerve root compression.

Sagittal spinopelvic malalignment in degenerative scoliosis patients: isolated correction of symptomatic levels and clinical decision-making.

Scoliosis Spinal Disord 2018 27;13:28. Epub 2018 Dec 27.

2Department of Orthopaedic Surgery, Rush University Medical Center, 1611 W. Harrison St., Suite 300, Chicago, IL 60612 USA.

Background: This study aims to determine if (1) loss of lumbar lordosis (LL), often associated with degenerative scoliosis (DS), is structural or rather largely due to positional factors secondary to spinal stenosis; (2) only addressing the symptomatic levels with a decompression and posterolateral fusion in carefully selected patients will result in improvement of sagittal malalignment; and (3) degree of sagittal plane correction achieved with such a local fusion could be predicted by routine pre-operative imaging.

Methods: A retrospective study design with prospectively collected imaging data of a consecutive series of surgically treated DS patients who underwent decompression and instrumented fusion at only symptomatic levels was performed. Pre- and post-operative plain radiographs and pre-operative magnetic resonance imaging (MRIs) of the spinopelvic region were analyzed. Read More

Potential pathological mechanisms of L3 degenerative spondylolisthesis in lumbar spinal stenosis patients: A case-control study.

J Orthop Sci 2018 Dec 27. Epub 2018 Dec 27.

Department of Orthopaedic Surgery, The University of Tokyo, 7-3-1 Hongo, Bunkyo-ku, Tokyo, 113-8655, Japan.

Background: Degenerative spondylolisthesis (DS) occurs mostly at L4. However, there are a small number of patients in whom it occurs only at L3. Accordingly, past reports elucidating the factors of DS have been primarily concerned with L4 DS, and few reports are available on DS at L3. Read More

Patient demographics and MRI-based measurements predict redundant nerve roots in lumbar spinal stenosis: a retrospective database cohort comparison.

BMC Musculoskelet Disord 2018 Dec 22;19(1):452. Epub 2018 Dec 22.

Department of Radiology, Schoen Clinic Hamburg Eilbek, Dehnhaide 120, D-22081, Hamburg, Germany.

Background: Up to 40% of patients diagnosed with lumbar spinal stenosis (LSS) show evidence of redundant nerve roots (RNR) of the cauda equina on their magnetic resonance images (MRI). The etiology of RNR is still unclear. Preoperative evidence of RNR is associated with a worse postsurgical outcome. Read More

Non-compressive postoperative cauda equina syndrome following decompression and transforaminal interbody fusion surgery.

BMJ Case Rep 2018 Nov 28;11(1). Epub 2018 Nov 28.

Anatomy, All India Institute of Medical Sciences, Bhubaneswar, Odisha, India.

Postoperative cauda equina syndrome (CES) is a known rare complication following lumbar disc surgery. Seldom are they seen following decompression for spinal stenosis and may be actually more frequent and under-reported? Emergent surgical exploration remains the mainstay of management as the factors responsible for postop CES remains a variety of compressive forces. Yet many a time postoperative imaging or surgical exploration fails to identify a pathology and this leads to an ischaemic theory responsible for CES. Read More

Pacemaker system replacement under local anesthesia allowing MRI access 7 years after the initial surgery: Two case reports.

J Rural Med 2018 Nov 29;13(2):185-187. Epub 2018 Nov 29.

Department of Cardiovascular Surgery, Shonai Amarume Hospital, Japan.

Older pacemaker systems, which are magnetic resonance imaging (MRI) incompatible, require replacement with compatible systems when patients are in need of MRI. Replacement involves extraction of the pacing lead, which is usually done with a laser sheath under general anesthesia. We report two cases of complete pacing system replacements allowing patient access to MRI. Read More

MR Imaging of the Spine: Urgent and Emergent Indications.

Semin Ultrasound CT MR 2018 Dec 19;39(6):551-569. Epub 2018 Oct 19.

Department of radiology, University of Miami Miller School of Medicine, Miami, FL.

Spinal emergencies and urgent conditions must be recognized early so that the diagnosis can be quickly confirmed and treatment can be instituted to possibly prevent permanent loss of function. The American College of Radiology provides guidelines for recognition of patients presenting with myelopathy or acute low back pain who require further evaluation for suspicion of more serious problems and contribute to appropriate imaging utilization. Spinal emergencies include spinal cord compression secondary to vertebral fracture or space occupying lesion, spinal infection or abscess, vascular or hematologic damage, severe disc herniation, and spinal stenosis.

Radicular Pain Syndromes: Cervical, Lumbar, and Spinal Stenosis.

Semin Neurol 2018 12 6;38(6):634-639. Epub 2018 Dec 6.

Department of Neurology, Boston University School of Medicine, Boston University Medical Center, Boston, Massachusetts.

Back pain is a top primary and urgent care complaint; radicular pain can be caused by herniation of the nucleus pulposus (intervertebral disc), spinal stenosis, or degenerative changes to the vertebrae. The focus of this clinical review will be the clinical approach and treatment of lumbar radicular pain, cervical radicular pain, and spinal stenosis. Usually localized through neurological history, exam, and imaging, specific signs and symptoms for lumbar radicular, spinal stenosis, and cervical radicular pain can help determine etiology.

Clinical and Radiological Outcomes of Foraminal Decompression Using Unilateral Biportal Endoscopic Spine Surgery for Lumbar Foraminal Stenosis.

Clin Orthop Surg 2018 Dec 21;10(4):439-447. Epub 2018 Nov 21.

Department of Orthopedic Surgery, Chungnam National University Hospital, Chungnam National University School of Medicine, Daejeon, Korea.

Background: Since open Wiltse approach allows limited visualization for foraminal stenosis leading to an incomplete decompression, we report the short-term clinical and radiological results of unilateral biportal endoscopic foraminal decompression using 0° or 30° endoscopy with better visualization.

Methods: We examined 31 patients that underwent surgery for neurological symptoms due to lumbar foraminal stenosis which was refractory to 6 weeks of conservative treatment. All 31 patients underwent unilateral biportal endoscopic far-lateral decompression (UBEFLD). Read More

The Prevalence of Cervical Foraminal Stenosis on Computed Tomography of a Selected Community-Based Korean Population.

Clin Orthop Surg 2018 Dec 21;10(4):433-438. Epub 2018 Nov 21.

Department of Orthopaedic Surgery, Daegu Catholic University Medical Center, Daegu, Korea.

Background: Cervical foraminal stenosis (CFS) is one of the degenerative changes of the cervical spine; however, correlations between the severity of stenosis and that of symptoms are not consistent in the literature. Studies to date on the prevalence of stenosis are based on images obtained from the departments treating cervical lesions, and thus patient selection bias may have occurred. The purpose of this study was to investigate the prevalence of CFS according to the site, extent, and morphology of stenosis using cervical computed tomography (CT) images obtained from patients who were visiting not because of symptoms related to the cervical spine, cervical pain, or upper limb pain.
