Background: The lack of mobility, motility and sunlight exposure put the orthopaedic patients at higher risk. Among the entire population of patients, adolescent and young adult members of our Indian society are considered as high-risk groups due to vitamin D inadequacy. As per the literature, the high prevalence of vitamin D inadequacy among the world's different countries prompted us to carry out this study. Our study aims to provide a report on vitamin D and related factors among orthopaedic patients in this part of our country. Materials and Methods: In our study, the normal individuals accompanying orthopaedic patients were formally enrolled for this study. Subjects were recruited based on simple variables such as age, gender, weight, height, history of taking nutritional supplements and concurrent diseases. Biochemical estimation of Vitamin D levels in 100 orthopaedic patient group, as well as the same number of control subject group. Serum PTH, calcium, alkaline phosphatase, phosphorus and routine blood investigations were done. Body height and height was used to calculate the BMI, and daily sun exposure was measured. All this consolidated data were analysed using SPSS software. Results: In this study a high prevalence of vitamin D deficiency was observed more in elderly individuals (46-50 years) than in younger patients. Vitamin D sufficiency in elderly individuals (46-50 years) was significantly less than the younger subjects. This difference in vitamin D sufficiency was statistically significant between the 35-40 and 45-50 years age group. Serum PTH among the patient group was significantly higher than of the control group. There was a negative correlation observed between Serum vitamin D levels and serum PTH levels. Conclusion: Our study helps build a consensus that vitamin D deficiency is a significant issue among orthopaedic patients. Specifically, mid-age or old patients are at a higher risk of vitamin deficiency in orthopaedic patients.
