Life (Basel) 2022 Jun 8;12(6). Epub 2022 Jun 8.

Department of Neurology, "Carol Davila" University of Medicine and Pharmacy, 050471 Bucharest, Romania.

In this review, we provide an update on the pathogenesis, diagnosis, and management of adults with idiopathic intracranial hypertension (IIH) and implications of the cerebral venous system, highlighting the progress made during the past decade with regard to mechanisms of the venous outflow pathway and its connection with the cerebral glymphatic and lymphatic network in genesis of IIH. Early diagnosis and treatment are crucial for favorable visual outcomes and to avoid vision loss, but there is also a risk of overdiagnosis and misdiagnosis in many patients with IIH. We also present details about treatment of intracranial hypertension, which is possible in most cases with a combination of weight loss and drug treatments, but also in selected cases with surgical interventions such as optic nerve sheath fenestration, cerebral spinal fluid (CSF) diversion, or dural venous sinus stenting for some patients with cerebral venous sinus stenosis, after careful analysis of mechanisms of intracranial hypertension, patient clinical profile, and method risks.

Automatic Grading of Disc Herniation, Central Canal Stenosis and Nerve Roots Compression in Lumbar Magnetic Resonance Image Diagnosis.

Front Endocrinol (Lausanne) 2022 6;13:890371. Epub 2022 Jun 6.

Department of Spinal Surgery, The Fifth Affiliated Hospital of Sun Yat-Sen University, Zhuhai, China.

Aim: Accurate severity grading of lumbar spine disease by magnetic resonance images (MRIs) plays an important role in selecting appropriate treatment for the disease. However, interpreting these complex MRIs is a repetitive and time-consuming workload for clinicians, especially radiologists. Here, we aim to develop a multi-task classification model based on artificial intelligence for automated grading of lumbar disc herniation (LDH), lumbar central canal stenosis (LCCS) and lumbar nerve roots compression (LNRC) at lumbar axial MRIs.

Mobility-Maintaining Facet Arthroplasty of the Lumbar Spine With the Second-Generation TOPS System: A Case Series.

Oper Neurosurg (Hagerstown) 2022 Jul 20;23(1):14-21. Epub 2022 Apr 20.

Arbeitsgemeinschaft Freier Wirbelsäulenchirurgen, Vienna, Austria.

Background: Lumbar spinal stenosis results from spinal canal narrowing and can lead to pain and dysfunction. Until recently, surgical treatment for lumbar spinal stenosis requiring an extensive decompression, with or without spondylolisthesis, had to balance pain relief with the long-term risks of spinal instability after decompression and adjacent segment disease (ASD) after spinal fusion. Spinal motion-preserving devices aim to reduce the incidence of ASD after posterolateral fusion and consequent need for revision surgery. Read More

3D-Printed Bionic Titanium Alloy Artificial Lamina Prevents Epidural Adhesion and Restores the Stability After Laminectomy in Pigs.

J Biomed Nanotechnol 2022 Mar;18(3):875-883

Department of Spine Surgery, Dongguan People's Hospital/Affiliated Dongguan Hospital, Southern Medical University, Dongguan, 523069, China.

Laminectomy can cause the dura mater to adhere to the surrounding scar tissue, leading to soft spinal stenosis after surgery. Although artificial laminae are considered ideal substitutes, they present challenges such as insecure fixation and insufficient bionics. In this study, we fabricated a bionic titanium alloy artificial lamina using three-dimensional (3D)-printing technology and evaluated its adhesion prevention and stability after laminectomy in pigs.

Hard collar immobilisation following elective surgery on the cervical spine: a cross-sectional survey of UK spinal surgeons.

Br J Neurosurg 2022 Jun 15:1-6. Epub 2022 Jun 15.

Division of Neurosurgery, Department of Clinical Neurosciences, Addenbrooke's Hospital, University of Cambridge, Cambridge, UK.

Introduction: Although mostly used in the management of spinal trauma, hard collar immobilisation is also used as an adjunct to recovery after elective cervical spine surgery. Many surgeons believe that bracing reduces the risk of non-union and pain and provides a subjective sense of security for patients. There is little if any, evidence for this practice and immobilisation can be a direct cause of adverse events. Read More
