A Safety and Efficacy Study for Treatment of Painful Vertebral Compression Fractures Caused by Osteoporosis

Doctors are studying an investigational treatment to be used during the vertebroplasty procedure when treating vertebral compression fractures (spine fractures) that may help to reduce pain and restore mobility. If one has experienced back pain for at least 4 weeks but not longer than 1 year, he/she may be eligible to participate. The purpose of this protocol is to describe the methods for the clinical evaluation of Cortoss for vertebroplasty in patients with painful osteoporotic compression fractures. Eligible patients with painful osteoporotic compression fractures of the spine are divided into two groups. Each enrolled patient will have the vertebroplasty procedure; however one group of patients will have the vertebroplasty procedure using polymethylmethacrylate \[PMMA\] (a Food and Drug Administration \[FDA\]-approved bone cement) and the other group of patients will have the vertebroplasty procedure using a relatively new (investigational) biomaterial called Cortoss.
