Vitamin D levels and Hounsfield units of the lumbar spine were recorded from computed tomography scans. Exclusion criteria included fragility fractures, lumbar surgery history, or lumbar bony\/metastatic lesions. The correlation between vitamin D levels and BMD was assessed; vitamin D deficiency was defined as below 30 ng\/mL.Results: Among the participants, 75% were vitamin D\u2013deficient, with an average vitamin D level of 25.0 ng\/mL. No patients had osteoporosis based on Hounsfield units; however, 5% of patients were in the osteopenic range. In patients with normal vitamin D levels, there was an inverse correlation between vitamin D levels and BMD measured by Hounsfield units (P=0.025). Higher lumbar spine Hounsfield unit measurements correlated with lower vitamin D levels in this nondeficient population.Conclusions: This study highlights a high prevalence of vitamin D deficiency in young orthopedic trauma patients, and it suggests a potential inverse relationship with BMD in patients with vitamin D levels &gt;30 ng\/mL. The absence of osteoporosis in our population raises questions about the influence of vitamin D on BMD in this young trauma patient demographic. Future research should explore the impact of vitamin D replacement on fracture union and investigate the interaction between vitamin D levels and bone health in the younger orthopedic trauma population.<\/jats:p>","DOI":"10.20408\/jti.2024.0038","type":"journal-article","created":{"date-parts":[[2024,12,26]],"date-time":"2024-12-26T07:16:27Z","timestamp":1735197387000},"page":"276-280","update-policy":"https:\/\/doi.org\/10.20408\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Vitamin
