Background: Vitamin D deficiency (VDD) is seen in all races, age groups, and ethnic backgrounds. VDD estimated to affect >1 billion people worldwide. The purpose of the present study is to characterize the extent of Vitamin D inadequacy and parathyroid hormone (PTH) levels among patients presenting to us for fracture management. Materials and Methods: A prospective case-control study was performed whereby serum Vitamin D levels and corresponding PTH levels were measured. The study subjects included patients >45 years of age irrespective of sex who presented with fracture as a result of trivial trauma. A total of 102 cases (34 intertrochanteric fracture, 66 fracture neck of femur, and 2 Colle's fracture) and 100 controls were included in the study. Result: Average serum hydroxy-vitamin D and serum PTH of cases 15.8 ± 5.25 ng/mL and 91.15 ± 6.03 pg/mL, respectively. Average S.25-OH Vitamin D and serum PTH of controls was 25.49 ± 3.79 ng/mL and 23.46 ± 3.79 pg/mL, respectively. Eighty (78.4%) cases were in insufficient range (Vitamin D between 10–30 ng/mL), 16 (15.6%) were deficient (Vitamin D <10 ng/mL), and only 6 (5.8%) were sufficient (Vitamin D >30 ng/mL). While in controls, 28% had sufficient and 72% had insufficient Vitamin D levels. There was no deficient control. Serum PTH levels were significantly raised in cases when compared to controls consistent with secondary hyperparathyroidism. Conclusion: This study gives us very important data regarding the prevalence of VDD and rise of PTH secondary to the former and this hormonal milieu in our body is an independent risk factor for increased incidence of fracture.
