Abstract
Purpose
We evaluated changes in bone mineral density and biochemical bone turn over markers resulting from intravenous administration of zoledronic acid for the purpose of increasing bone mineral density and decreasing bone turnover rate in patients who had received operative treatment after hip fracture.
Materials and Methods
We carried out a retrospective study of 34 patients who had received injections of zoledronic acid after surgical treatment for hip fracture from January 2009 to June 2010, with a follow up period of more than one year. We evaluated pre and post T-scores of DXA in spine, proximal femur and femoral neck along with biochemical bone metabolic markers, and we then analyzed each factor.
Results
T score was enhanced in all cases with pre T-score -4.2 and post T-score -3.3 revealing statistical significance (P<0.05). In addition, two biochemical bone turnover markers were observed to decrease in most patients. Three days after drug administration, 7 patients(20.6%) had minor adverse effects. There were no serious complications such as atrial fibrillation.
Conclusion
No major adverse effects were observed, only minor ones in patients who had been injected with zoledronic acid for the prevention of osteoporotic fracture after surgical treatment for hip fracture. We confirmed the affirmative effects on changes in bone mineral density and biochemical bone turn over markers associated with the use of this drug.
