Objective The incidence of bone fractures rapidly increases as people age, mostly due to bone loss resulting from osteoporosis. The purpose of this study is to compare the rates of repeat vertebroplasty in osteoporotic patients treated with or without zoledronic acid (ZOL) infusion following initial vertebroplasty. Research design and methods We conducted a retrospective chart review of osteoporotic patients who underwent vertebroplasty from June 2009 to June 2012. ⋯ In the ZOL-treated group, only 4% of the patients (2/51) required a second vertebroplasty, compared to 13% (206/1595) in the non-ZOL-treated group (p = 0.032). Conclusions The results indicate that osteoporotic patients who undergo vertebroplasty are significantly less likely to require reoperation if treated with zoledronic acid infusion. However, since the number of male patients in the ZOL-treated group was limited, and since Taiwan's National Health System program does not cover the cost of receiving zoledronic acid infusions for male patients, the conclusion seems to be less certain for male osteoporotic patients.
