MORFOMETRIA DE RM DE DISCOS LOMBARES E CORPOS VERTEBRAIS EM CORRELAÇÃO COM O NÍVEL SÉRICO DE VITAMINA D

Abstract

ABSTRACT Introduction: The knowledge of the intervertebral disc morphology and its relation with the vertebrae is vital for managing degenerative spine disease. It is imperative to study the role of preventable and treatable causes, such as Vitamin D deficiency, so that standard guidelines can be framed for apt management. Objective: To evaluate the correlation between serum vitamin D levels and MRI morphometry of lumbar intervertebral discs. Methods: A total of 100 subjects (20-40 years) underwent an MRI of the lumbosacral spine. Intervertebral disc and vertebral body heights were measured, and disc degenerative changes were noted. Serum vitamin D levels were correlated with disc changes using the Pearson/Spearman rank correlation coefficient. A p-value of <0.05 was considered significant. Results: Vitamin D deficiency showed a high prevalence in patients with disc degenerative diseases, even in young adults and females with more severe vitamin D deficiency than males (p-value < 0.001). However, a significant relationship between vitamin D levels and disc or vertebral body heights could not be established. Conclusion: Vitamin D deficiency is more prevalent in patients with disc degenerative changes; however, its effect on disc and vertebral body heights needs to be extrapolated further in larger studies. Level of Evidence I; Cross-Sectional, Observational Study.
