Morphometric Analysis of Pedicles in Adult Human Dried Lumbar Vertebrae: A Cross-Sectional Study

Abstract

Introduction: The human vertebral column is comprised of 33 vertebrae, five of which are lumbar. The first four (L1 to L4) are typical, while the fifth (L5) is atypical.

Aim and Object: This research aims to analyse the morphology of lumbar vertebrae by collecting their various morphometric data which provide pertinent information to orthopaedicians, neurosurgeons, anatomists, and biomechanical engineers working to enhance the health and well-being of people with spinal disorders.

Material and Methods: The research was conducted on a total of 100 dry adult human lumbar vertebra [typical – 50 & atypical - 50] of unknown sex and age, from the Department of Anatomy at Geetanjali Medical College and Hospital, Udaipur. The typical and typical lumbar vertebrae were determined as per the guidelines mentioned in the standard reference book of anatomy. The sample were collected at random and the necessary data was collected over the course of 12-16 months.

Results:  in the present study, a comparison within the group showed significant differences in pedicle width (p= 0.012) but not in pedicle height or interpedicular distance (p > 0.05). When comparing between typical and atypical lumbar vertebrae, significant differences were observed in pedicle width (p < 0.001), whereas pedicle height and interpedicular distance did not show significant variation (p > 0.05). These findings highlight distinct morphological differences, particularly in pedicle width, between typical and atypical lumbar vertebrae, suggesting structural adaptations in atypical vertebrae.

Conclusion: These findings contribute to a growing body of literature on vertebral anatomy, offering insights that can improve patient care and outcomes in spinal surgery and orthopedic interventions.
