Glass -polyalkenoate cement: An alternative material for kyphoplasty in osteoporotic vertebral compression fractures - An ex vivo study

8 vertebral bodies were used in order to compare pressure distribution in the endplate of the human thoracolumar vertebrae after kyphoplasty with PMMA and glass-polyalkenoate-cement (gpc). The pressure distribution after application of physiological compression forces of 1000 N shows gpc as being superior to PMMA, suggesting it to be a promising material for the treatment of vertebral osteoporotic fractures by reducing the risk of adjacent vertebral fractures.394
