Background: Traditionally, vitamin D has been referred to as the sunlight vitamin or the anti-ricketic component. The present study was conducted to assess prevalence of vitamin D deficiency in orthopaedic patients. Materials & Methods: 140 orthopaedic patients of both genders were enrolled. After determining weight and height, the body mass index (BMI) was computed. The proportion of the body's surface area exposed each day and the average length of exposure were recorded in order to evaluate daily exposure to direct sunlight. Results: Out of 140 patients, males were 82 and females were 58. Vitamin D had frank deficiency (<20 ng/ml) was seen in 72, insufficiency (21–29 ng/ml) in 40 and sufficient (>30 ng/ml) in 28 cases. The difference was significant (P< 0.05). BMI was 28.5 kg/m2, 26.3 kg/m2 and 25.1 kg/m2 in patients with vitamin D deficiency, insufficiency and sufficiency. The mean PTH was 43.1 pg/ml, 35.7 pg/ml and 38.2 pg/ml. The mean calcium was 9.5 mg/dl, 9.4 mg/dl and 9.8 mg/dl. The mean phosphorus was 3.1 mg/dl, 3.0 mg/dl and 3.5 mg/dl. The mean alkaline phosphate level was 92.3 U/L, 94.6 U/L and 96.7 U/L. Daily sunlight use >30 min was seen 40, 9 and 5 patients with vitamin D deficiency, insufficiency and sufficiency. The difference was non- significant (P> 0.05). Conclusion: Lack of sunshine exposure, insufficient food consumption and supplementation, as well as other factors like age, obesity, medication use, sunscreen use, covering entire skin with clothing, and skin pigmentation, are risk factors for low vitamin D levels.
