Introduction: Orthopaedic surgeons may find it useful to know the prevalence of vitamin D sufficiency and insufficiency when treating patients to avoid potential complications during and after surgery, to maintain good physical function, and to maintain independence in daily life. This observational study's aim was to assess vitamin D serum levels in individuals who presented with orthopaedic disease. Materials & Methods: The 262 patients from both genders who were included in the study were subjected to cross-sectional analysis for the current study. After an overnight fast without venostasis, a 10 ml blood sample was taken from each study participant. According to a recent consensus, the participants were categorised as vitamin D deficient, insufficient, or sufficient based on 25(OH)D values of 20 ng/ml, 21-29 ng/ml, and 30-100 ng/ml, respectively. Results: The prevalence of vitamin D deficiency in females was higher than in males (20 ng/dl), although this difference was not statistically significant (p-value = 0.65). Males and females, respectively, had vitamin D insufficiency rates of 31.9% and 37.4% in the age group of 41 to 60 years. Both the difference in vitamin D deficiency and the difference in vitamin D insufficiency were significant in the 61-80 age group for both males and females. Discussion & conclusion: vitamin D deficiency is certainly present among orthopaedic patients of all ages and occurs at an alarmingly high rate. Low vitamin D levels can be caused by poor dietary consumption, inadequate sun exposure, inadequate supplementation, and other issues. Public education regarding the necessity for dietary adjustments and lifestyle changes that allow for more opportunities to be exposed to sunshine is necessary.
