La vitamina-D para la prevención de fracturas osteoporóticas.

Introduction: The objective of this study was to show the initial results of an oral vitamin-D and calcium supplementation program in patients who had suffered a hip fracture for the prevention of subsequent fractures considered osteoporotic. Method: Prospective comparative cohorts study in patients older than 65 operated for hip fracture. The patients were divided into two groups according to the serum level of vitamin-D at admission: 1) hypovit-D group, 58 patients who were prescribed oral vitamin-D and calcium at discharge; 2) control group, 13 patients with a normal level of vitamin-D who did not have that supplementation. Results: The sample size could not be completed due to the scarcity of patients with normal vitamin-D levels. The subsequent fracture rate in the following two years was 20.7% in the hypovit-D group and 15.4% in control group, with no significant difference (p = 0.664). Conclusion: provisionally, with the available data, oral vitamin-D and calcium supplementation have not shown effectiveness in preventing a subsequent hip fracture.
