Low back pain (LBP) impairs the quality of life and rises healthcare costs. The association of spine degeneration and LBP with metabolic disorders have been reported, previously. However, metabolic processes related with spine degeneration remained unclear. We aimed to analyze whether serum thyroid hormones, parathormone, calcium, and vitamin D levels were associated with lumbar intervertebral disc degeneration (IVDD), Modic changes, and fatty infiltration in the paraspinal muscles. ⋯ Serum hormone, vitamin D, and calcium levels were associated with not only IVDD and Modic changes but also with fatty infiltration in the paraspinal muscles, mainly at upper lumbar levels in patients with symptomatic backache presenting to a tertiary care center. Complex inflammatory, metabolic, and mechanical factors present in the backstage of spine degeneration.

This study aims to report a new distribution pattern of Modic changes (MCs) in patients with lumbar disc herniation (LDH) and investigate the prevalence, correlative factors and clinical outcomes of asymmetric Modic changes (AMCs). ⋯ AMCs were a more common phenomenon than SMCs in this study. The asymmetric and symmetric distribution of MCs was closely related to LDH position. AMCs were related to leg pain and higher pain levels. Surgery can achieve satisfactory clinical improvement for asymmetric and symmetric MCs.
