Abstract
Introduction: Understanding normal variations in lumbar spine morphology is crucial for accurate clinical diagnoses and interventions. This study aimed to contribute significantly to the global knowledge of lumbar vertebrae by analyzing various morphometric parameters comprehensively. The intricate interplay of vertebral dimensions, spinal canal geometry, and intervertebral disc proportions contributes to the overall functionality of the lumbar spine. This research addresses gaps in existing literature, providing a holistic perspective on multiple parameters simultaneously.
Methods: Adult male and female participants were carefully selected for high-resolution imaging, utilizing magnetic resonance imaging (MRI) and computed tomography (CT) to capture detailed lumbar spine images. Morphometric measurements were extracted using specialized software, enabling precise quantification. Statistical analyses, including t-tests and regression models, were applied to assess differences, while subgroup analyses accounted for potential confounding factors such as age and body mass index (BMI).
Results: The findings align with historical and contemporary research, emphasizing the study's significance. The study revealed sexual dimorphism in lumbar spinal canal dimensions, vertebral bodies, and intervertebral discs. Notable observations included an increase in transverse diameters from L1 to L5, larger vertebral body diameters in males, and consistent trends in anatomical variations across levels. The anteroposterior diameter of the spinal canal exhibited a gradual decrease from L1 to L5, with males consistently showing larger diameters than females. Id values remained constant across levels, suggesting no significant sexual dimorphism in intervertebral disc proportions.
Conclusion: This comprehensive analysis of lumbar spine morphometry provides valuable insights into normal variations and potential clinical implications. Sexual dimorphism underscores the importance of gender-specific reference values in clinical practice, contributing to the existing knowledge of lumbar spine anatomy
