Many recent reports demonstrated high rates of vitamin D deficiency in numerous segments of Indian population but no study has been reported so far from India, which focuses specifically on vitamin D status in orthopaedic patients. This study finds out the prevalence of vitamin D deficiency in orthopaedic patients in India.


Vitamin D levels of 1132 patients were measured from OPD and Emergency Department of S.N. Medical College, Agra from 1 November 2011 to 31 October 2013. Serum 25(OH) vitamin D, calcium, phosphorus, alkaline phosphatase and routine blood investigations were done. BMI and daily sun exposure were measured.


Out of 1132 patients included in our study, 732 (64.7%) were males and 400 (36.3%) females. Vitamin D deficiency (<30 ng/ml) was present in 1034 patients (91.3%); among them, 693 patients (61.2%) had vitamin D level <20 ng/ml and only 98 patients (8.7%) had sufficient levels of vitamin D. Vitamin D deficiency was more in elderly patients (61-80) than in younger patients. Among 1132 patients, 670 males (91.5%) and 364 females (91.0%) were found to have serum 25(OH) vitamin D levels <30 ng/dl cut-off for vitamin D sufficiency (p-value = 0.75). Vitamin D levels were lower in patients with less mean sun exposure time. BMI level was more in deficient group than the sufficient group relatively.


High incidence of vitamin D insufficiency and deficiency likely exists across all age groups among orthopaedic patients. Screening and treating hypovitaminosis D appears to be important in this patient population.
