ABSTRACT
Background: An essential element in the equilibrium of calcium in the body is Vitamin D. It prompts adding calcium into the circulation. As a result, it could have a significant role in preventing the occurrence of high and low energy fractures. The point of this study was to find an association of Vitamin D deficiency with low or high energy fractures among patients older than 45 years old in King Abdulaziz Medical City in Riyadh. Method: This was a retrospective cross-sectional study that was conducted from January 2015 to December 2017 at the Orthopedic department in KAMC-Riyadh. A total of 230 Saudi fracture patients older than 45 years old with measured Vitamin D levels were reviewed. The variables included age, gender, 25-hydroxyvitamin D level, and type of fracture; high vs. low-energy fracture. The deficiency was considered as serum concentrations of 25(OH)D<50 nmol/L. Results: There was a high prevalence of 25-hydroxyvitamin D deficiency 25(OH)D<50 nmol/L in (62%) among the study sample. This study found no association between 25-hydroxyvitamin D deficiency with fracture type (p=0.75) with high energy fractures (63%, 66/105) vs. low energy fractures (61%, 76/125), respectively. Conclusion: In spite of the high prevalence of deficiency within all fracture patients, these results are comparable to previous studies on the normal non-fracture population. More studies are required to look into more factors that might increase the probability of fractures..
