CDUNeXt: efficient ossification segmentation with large kernel and dual cross gate attention.

Ossification of the ligamentum flavum (OLF) is the main causative factor of spinal stenosis, but how to accurately and efficiently identify the ossification region is a clinical pain point and an urgent problem to be solved. Currently, we can only rely on the doctor's subjective experience for identification, with low efficiency and large error. In this study, a deep learning method is introduced for the first time into the diagnosis of ligamentum flavum ossificans, we proposed a lightweight, automatic and efficient method for identifying ossified regions, called CDUNeXt.

Animal Models of Intervertebral Disc Diseases: Advantages, Limitations, and Future Directions.

Animal models are valuable tools for studying the underlying mechanisms of and potential treatments for intervertebral disc diseases. In this review, we discuss the advantages and limitations of animal models of disc diseases, focusing on lumbar spinal stenosis, disc herniation, and degeneration, as well as future research directions. The advantages of animal models are that they enable controlled experiments, long-term monitoring to study the natural history of the disease, and the testing of potential treatments.

Risk of Post-Traumatic Spinal Cord Injury in Patients with Stenosis of the Cervical Spine: A Systematic Review and Meta-Analysis.

Introduction: Cervical stenosis (CS) is the pathologic narrowing of the central canal of the cervical spine. It is often incidentally discovered. It is unclear whether pre-existing CS can lead to worse outcomes and higher incidences of post-traumatic spinal cord injury (SCI).

Adjacent Level Canal Area Changes up to 2 years after Lumbar Spinal Stenosis Decompressive Surgery.

Study Design: A secondary analysis of data from the NORDSTEN-spinal stenosis trial (SST).

Objective: The aim of the present study was to investigate whether the dural sac cross-sectional area (DSCA) on magnetic resonance imaging (MRI) of adjacent segments decreases after decompressive surgery due to lumbar spinal stenosis (LSS) up to 2 years postoperatively, and to investigate possible associations with baseline variables, including preoperative patient and radiological characteristics, and surgical method used.

Background: Lumbar spinal stenosis (LSS) is a major cause of pain and disability in older individuals worldwide. Although increasing studies of traditional machine learning (TML) and deep learning (DL) were conducted in the field of diagnosing LSS and gained prominent results, the performance of these models has not been analyzed systematically.

Atraumatic Cervical Disc Herniation With Rapidly Progressive Myelopathy in a 47-Year-Old Male: A Case Report.

Atraumatic acute myelopathy caused by idiopathic disc herniation is rare. This case presents a 47-year-old male with a sudden onset of severe neck pain and weakness upon waking that progressively worsened. His rapidly progressive myelopathy led to an MRI of the cervical spine, revealing severe spinal canal stenosis at the C6-C7 level due to a large disc herniation deforming the spinal cord.

Analysis of the Thickness of Ligamentum Flavum and Its Relationship With Degenerative Disc Changes at L3-4, L4-5, and L5-S1 Levels in Patients Undergoing Magnetic Resonance Imaging (MRI) of the Lumbosacral Spine.

Background Low back pain (LBP) is the leading cause of disability among working-age adults, with its prevalence increasing with age and peaking in the 45-54 age group. It is common practice for clinicians to conduct advanced imaging procedures, such as computed tomography (CT) and magnetic resonance imaging (MRI) when a patient presents with LBP. The objective of this study was to measure and analyze the width of the ligamentum flavum (LF) on each side and the extent of degeneration of the disc at the L3-4, L4-5, and L5-S1 levels.

Pneumorachis mimicking lumbar disc herniation combined with lumbar spinal stenosis: A case report and literature review.

Rationale: Pneumorachis is an uncommon lesion of the spinal canal, which is often asymptomatic. The pathogenesis and treatment strategies are uncertain because only a few cases have been reported. Some patients were treated with percutaneous aspiration or percutaneous endoscopic treatment, but poor pain release and symptom recurrence were observed.

Endoscopic Epidurolysis for the Management of Chronic Spinal Pain: A Delphi-Based Italian Experts Consensus.

Introduction: Endoscopic epidurolysis (EE) is a minimally invasive procedure used to manage chronic spinal pain, particularly in cases unresponsive to traditional treatments. Despite its growing recognition, the literature lacks comprehensive guidelines on its optimal use. This study utilized a modified Delphi approach to gather expert consensus on best practices for EE in the Italian pain therapy network.

Inter-observer variability in the classification of lumbar foraminal stenosis in magnetic resonance imaging using different evaluation scales.

Background: The evaluation of lumbar spine degeneration on magnetic resonance imaging (MRI) is prone to inter-reader variability, including when assessing foraminal changes. This variability, often due to subjective criteria and inconsistent terminology, may affect clinical correlations. Standardized criteria could help improve agreement among readers.

Background: Diffuse idiopathic skeletal hyperostosis (DISH) is a systemic non-inflammatory disorder characterized by enthesopathy and osteophyte formation. DISH can also cause several other symptoms. Limited range of motion (ROM) is the most common symptom; however, dysphagia and respiratory distress are clinically important symptoms.

Background: Lumbar epidural injections have been studied as symptomatic treatments for lumbar spinal stenosis (LSS). However, results about their efficacy have been controversial, and data regarding their use is scarce. Our purpose in this article is to study the efficacy of epidural injections in the management of pain and disability in patients suffering from spinal stenosis, to study the factors which can affect their efficacy, and to discuss whether they could replace surgery or not.

Comparative efficacy and fusion outcomes of unilateral bi-portal endoscopic transforaminal lumbar interbody fusion versus minimally invasive transforaminal lumbar interbody fusion in treating single-segment degenerative lumbar spondylolisthesis with lumbar spinal stenosis: a two-year retrospective study.

Background: Degenerative lumbar spondylolisthesis (DLS) with lumbar spinal stenosis (LSS) is a common condition resulting in substantial lower back pain and disability. Surgical intervention is recommended only when conservative treatment fails. This study compared UBE-TLIF and MIS-TLIF regarding clinical outcomes and fusion rates in patients with single-segment DLS with LSS.

Auto-Rad: End-to-End Report Generation from Lumber Spine MRI Using Vision-Language Model.

Lumbar spinal stenosis (LSS) is a major cause of chronic lower back and leg pain, and is traditionally diagnosed through labor-intensive analysis of magnetic resonance imaging (MRI) scans by radiologists. This study aims to streamline the diagnostic process by developing an automated radiology report generation (ARRG) system using a vision-language (VL) model. We utilized a Generative Image-to-Text (GIT) model, originally designed for visual question answering (VQA) and image captioning.
