Abstract
This is a retrospective analysis of a consecutive series of patients undergoing vertebroplasty and vertebral augmentation in an outpatient setting for high degree osteoporotic vertebral fractures or vertebra plana using consistently low volumes (less than 3 cc) of Cortoss® cement, rather than polymethylmethacrylate (PMMA). The results in these patients demonstrate that it is both technically feasible to do vertebroplasty on these patients and using a low volume hydrophilic silica-based cement is effective in providing diffuse vertebral body fill with minimal complications. There was no increased risk of complications, such as cement leakage, displacement of bone fragments, or progression of the angulation. Specifically, with over a 24-month follow-up, the preoperative collapse or angulation did not worsen and none of the patients developed adjacent level fractures or required further surgery at the involved vertebral level.
