Quantitative analysis of 3D spinal deformities includes measurements related to individual vertebrae and measurements related to the overall shape of the spine. For the latter aspect, we propose to build a 3D model of the line that connects all vertebrae centres. We present two methods that allow reconstructing this vertebral body line in a quick and easy way. Various new descriptors of the spinal shape can be automatically computed. A study is under way to assess their clinical relevance and reliability.

Characterization of a Novel Col1a1 Osteogenesis Imperfecta Mouse Model with Insights into Skeletal Phenotype, Fragility, and Therapeutic Evaluations.

Osteogenesis imperfecta (OI) is an inheritable skeletal disorder characterized by bone fragility often caused by pathogenic variants in the COL1A1 gene. Current OI mouse models with a glycine substitution in Col1a1 exhibit excessive severity, thereby limiting long-term pathophysiological analysis and drug effect assessments. To address this limitation, we constructed a novel OI mouse model mimicking a patient with OI type III.

Background: The Spinal Instability Neoplastic Score (SINS) is used in determining instability in patients with spinal metastases. Intermediate scores of 7 to 12 suggest possible instability, but there are no clear guidelines to address patients with these scores.
Methods: We searched in PubMed, EMBASE, and Cochrane databases for studies that included patient demographics, tumor histology, surgical or radiotherapy management, and outcomes of patients with intermediate SINS.
Etiological and clinical characterization of longitudinally extensive spinal cord lesions: A 12-year tertiary center experience.

Department of Neurology, Hospital General Universitario Gregorio Marañón, Madrid, Spain.
Introduction: Longitudinally extensive spinal cord lesions (LESCL) are characterized by T2-hyperintense signals spanning at least three vertebral body segments, with neuromyelitis optica spectrum disorders (NMOSD) being a significant cause. This study aimed to characterize the clinical, radiological, serological, and cerebrospinal fluid (CSF) features of LESCL and to compare NMOSD and non-NMOSD cases.
Methods: We conducted a retrospective cross-sectional study of adult patients diagnosed with LESCL at our center over a twelve-year period collecting data on demographics, clinical presentations, MRI findings, CSF analysis, and serological testing for AQP4-IgG and MOG-IgG antibodies.
Longitudinal Assessment of Intersegmental Abnormalities in the Lumbar Spine of Adolescent Competitive Alpine Skiers Over 48 Months.

Department of Radiology, Balgrist University Hospital, Faculty of Medicine, University of Zurich, Zurich, Switzerland.
Background: Overuse-related intersegmental abnormalities in the spine of competitive alpine skiers are common findings. However, longitudinal changes in intersegmental abnormalities and symptoms throughout adolescence have not been assessed.
Purpose: To longitudinally assess and compare overuse-related spinal intersegmental abnormalities in adolescent competitive alpine skiers over 48 months and to compare magnetic resonance imaging (MRI) findings in asymptomatic and symptomatic skiers.
Vertebral level in pregnancy according to the posterior superior iliac spine: an observational study.

Department of Anesthesiology, West China Second University Hospital, Sichuan University, 20#, Section 3 Renmin Nan Road, Chengdu, Sichuan, 610041, PR China.
Background: While the line joining the posterior superior iliac spine (PSIS) intersects a relatively stable sacral vertebra, it does not directly facilitate the localization of lumbar interspace or assist in the positioning for neuraxial anesthesia. Our study aimed to explore the potential of the PSIS line as a reference point and to determine its practical applicability in clinical settings.
Methods: We consecutively enrolled pregnant women with gestational ages ranging from 24 to 38 weeks scheduled for magnetic resonance imaging (MRI) examination.
