schmorl's nodes

STUDY DESIGN: In vitro biomechanical study. OBJECTIVE: This study evaluated the influence of localized trabecular bone strength deficits and loading rate as determinants of Schmorl's node and fracture lesion incidence. The failure load (ultimate compression tolerance (UCT)), loading stiffness, and failure morphology were assessed after acute compression loading and failure. SUMMARY OF BACKGROUND DATA: The cartilaginous endplate is vulnerable to injuries such as Schmorl's nodes and fracture lesions...

OBJECTIVE: Using whole spine sagittal T2 MRI, we aimed to compare the severity and prevalence of disc degeneration (DD) in axial SpA patients vs the general population and to determine any association between spinal inflammation, structural changes, mobility and DD among SpA patients. METHODS: Two prospectively collected cohorts of SpA patients ( n  = 411) and the general population ( n  = 2007) were recruited. Eventually, 967 participants from the populational cohort and 304 participants from the SpA cohort were analysed...

STUDY DESIGN: Retrospective observational study. OBJECTIVE: To describe the epidemiology of Schmorl's nodes (SN) of primarily developmental cause (SNd) and SN of primarily acquired cause (SNa) separately in the thoracic spine in subjects aged 35-90 years old. SUMMARY OF BACKGROUND DATA: The epidemiology of SN and its relationship with age and gender remain controversial. Based on a pathophysiological hypothesis and the different morphological characteristics, two subtypes of SN may exist and should be considered separately...

STUDY DESIGN: Diagnostic test study. OBJECTIVE: To determine the reliability and validity or diagnostic accuracy of two previously described endplate structural defect (EPSD) assessment methods. SUMMARY OF BACKGROUND DATA: Studies of EPSD may further the understanding of pathoanatomical mechanisms underlying back pain. However, clinical imaging methods used to document EPSD have not been validated, leaving uncertainty about what the observations represent...

This article comprehensively reviews current imaging concepts in spinal infection with primary focus on infectious spondylodiscitis (IS) as well as the less common entity of facet joint septic arthritis (FSA). This review encompasses the multimodality imaging appearances (radiographs, CT, MRI, and nuclear imaging) of spinal infection-both at initial presentation and during treatment-to aid the radiologist in guiding diagnosis and successful management. We discuss the pathophysiology of spinal infection in various patient populations (including the non-instrumented and postoperative spine) as well as the role of imaging-guided biopsy...

BACKGROUND: Osteoporotic vertebral compression fractures (OVCFs) are the most common type of fragility fracture. Distinguishing between OVCFs and other types of vertebra diseases, such as old fractures (OFs), Schmorl's node (SN), Kummell's disease (KD), and previous surgery (PS), is critical for subsequent surgery and treatment. Combining with advanced deep learning (DL) technologies, this study plans to develop a DL-driven diagnostic system for diagnosing multi-type vertebra diseases...

PURPOSE: To study the distribution of lumbar Modic changes (MC) in low back pain patients, and to explore the relationship between Modic changes and age, gender, segment and lumbar degeneration diseases (disc degeneration, spinal stenosis, lumbar spondylolisthesis). PATIENTS AND METHODS: Modic changes were counted and analysed in 500 randomly selected patients who visited the outpatient clinic for lumbar spine MRI for low back pain from 2019 to 2022. The relationship between Modic changes and bulging disc, protrusion, extrusion, sequestration, Schmorl's node, spinal stenosis, and lumbar spondylolisthesis was studied...

PURPOSE: Degenerative spinal conditions, including disc degeneration (DD), Schmorl nodes (SN), and endplate signal changes (ESC), are pervasive age-associated phenomena that critically affect spinal health. Despite their prevalence, a comprehensive exploration of their distribution and correlations is lacking. This study examined the prevalence, distribution, and correlation of DD, SN, and ESC across the entire spine in a population-based cohort. METHODS: The Wakayama Spine Study included 975 participants (324 men, mean age 67...

Background and Objectives : Schmorl's nodes (SNs), formed by the herniation of intervertebral discs into adjacent vertebral bodies, are generally asymptomatic and do not require treatment. However, certain types of SNs can cause intractable back pain. Case Presentation : A 63-year-old man presented to our hospital with back pain after a fall 1 month prior. Physical examination revealed back pain that worsened with movement and paraspinal tenderness. Magnetic resonance imaging (MRI) performed immediately after presentation revealed subacute to chronic compression fractures with SNs at the upper endplates of the 11th and 12th thoracic and 1st lumbar vertebrae...

Scheuermann's disease is a rigid progressive kyphosis occurring in late childhood to adolescence. It is the most common cause of sagittal imbalance and angular progressive kyphosis in adolescents associated with back pain. The exact etiology of the disease is unclear, but it is characterized by defective growth of the end plate that may result from excessive mechanical stress on a weakened end plate during spinal growth. Several other theories have been proposed, and it is thought to be a multifactorial disease occurring as a result of the interplay of multiple factors...

OBJECTIVE: Skeletal populations from Byblos, Beirut, and Tyre were studied to assess mechanical stress along the Roman Phoenician coast. MATERIALS: The sample included 153 adult skeletons. METHODS: Skeletal remains were macroscopically assessed for osteoarthritis, intervertebral disc disease (IDD), and Schmorl's nodes. RESULTS: The Byblos population experienced higher levels of mechanical stress than the Beirut and Tyre ones...

BACKGROUND: Compared with Caucasians, East Asians have a lower incident of back pain, lower prevalence and severity of osteoporotic vertebral fracture and lumbar spine degeneration. AIM: This study compares radiographic spine degeneration features of older Chinese women (as an example of East Asians) and older Italian women (as an example of Caucasians) with a focus on the thoracic spine. METHODS: From two population-based epidemiological studies conducted in Hong Kong, China and Rome, Italy, 297 pairs (mean age: 73...

Massive bone destruction in a human right proximal femur is described and differentially discussed in this case study. The individual was an older adult female buried at the ancient Nubian site of Tombos (modern-day Sudan) dating to the early Napatan/Third Intermediate Period (c. 1069-750 BCE). The right femur displayed a pathologic fracture with extensive lytic destruction and resorption of the entire femoral neck, most of the femoral head, and trochanters. Macroscopic and radiographic analyses revealed cortical thinning of the proximal diaphysis with new bone formation enclosing the medullary cavity...

BACKGROUND: Several magnetic resonance (MR) techniques have been suggested for radiation-free imaging of osseous structures. PURPOSE: To compare the diagnostic value of ultra-short echo time and gradient echo T1-weighted MRI for the assessment of vertebral pathologies using histology and computed tomography (CT) as the reference standard. STUDY TYPE: Prospective. SUBJECTS: Fifty-nine lumbar vertebral bodies harvested from 20 human cadavers (donor age 73 ± 13 years; 9 male)...

STUDY DESIGN: A descriptive, cross-sectional cadaver study. OBJECTIVE: This study aimed to provide a thorough depiction of vertebral endplate defects classified based on their morphological features and reported with respect to size, location, and prevalence in human cadaveric spines of older adults. SUMMARY OF BACKGROUND DATA: Back pain has been associated with vertebral endplate defects; however, findings have been inconsistent. This is partially due to miscommunication surrounding the classification of endplate defects observed using clinical imaging, and limited knowledge of the types of defects present on the endplate and their prevalence...

INTRODUCTION: A novel classification scheme for endplate lesions, based on T2-weighted images from magnetic resonance imaging (MRI) scan, has been recently introduced and validated. The scheme categorizes intervertebral spaces as "normal," "wavy/irregular," "notched," and "Schmorl's node." These lesions have been associated with spinal pathologies, including disc degeneration and low back pain. The exploitation of an automatic tool for the detection of the lesions would facilitate clinical practice by reducing the workload and the diagnosis time...

OBJECTIVE: This study aimed to determine the prevalence of the ossification of the ligamenta flava (OLF) among skeletal remains from Poland. MATERIALS AND METHODS: 124 skeletons aged 25 years and older were analyzed. The presence and size of OLF were observed macroscopically. OLF was recorded at the cranial and caudal attachment sites of each vertebra. The following factors were analyzed: age at death, sex, and presence of other spondyloarthropathies. RESULTS: The crude prevalence of OLF in the analyzed series was 68...

PURPOSE: Percutaneous vertebroplasty(PVP) has been widely used in treating symptomatic Schmorl's nodes(SNs). However, there were still some patients with poor pain relief. At present, there is a lack of research to analyze the reasons for poor efficacy. METHODS: Review the SNs patients treated with PVP in our hospital from November 2019 to June 2022, collect their baseline data. Reverse reconstruction software was used to calculate the filling rate of bone edema ring(Rf )...
