A Controlled Trial of Vertebroplasty for Acute Painful Osteoporotic Fractures
The objective of this study is to gather data regarding the efficacy, safety and cost-effectiveness of percutaneous vertebroplasty in the acute fracture group with fractures less than 6 weeks old. The AVAMAX vertebroplasty kits (Care Fusion) will be used for all vertebroplasties.
The primary effectiveness analysis will be based on the number of patients whose numeric rating pain score drops from above 7 out of 10 at baseline to below 4 out of 10 at two weeks post-intervention. Our hypothesis is that the vertebroplasty group will have a significantly larger proportion of patients achieving pain reduction than the control group. A secondary analysis will compare the change in mean pain scores and specific activity related pain scores between the two groups at 3 days, 14 days and at 1, 3 and 6 months. Another secondary effectiveness analysis will include the mean change in the back-pain specific limitation in function as quantified by the Roland Scale at these same data collection time points.

|Primary Completion Date:||May 2015 (Final data collection date for primary outcome measure)|
Active Comparator: AVAMAX
Avamax vertebroplasty kits provided by Care Fusion
AVAmax radiopaque bone cement is injected into the vertebral body using a 13 G or 11 G vertebroplasty needle.
No Intervention: Simulated injection procedure
Patient will be unaware as to whether the control procedure or vertebroplasty had been performed since full sterile preparation, sedation and simulated injection procedure will be used.
