Abstract:
[Objective]To compare the difference between single and double balloon kyphoplasty to treat osteoporotic vertebral body.[Method]Twenty osteoporotic vertebral bodies were harvested from 10 embalmed cadavers,alternatingly assigned to either the single and double group.All vertebraes were compressed by 25% of their initial height using materials testing machine to create vertebral compression fractures and determine their augmented strength and stiffness before and after injecting the cement.Precompression,postcompression and posttreatment height of vertebrae were measured.[Result]Both treatments resulted in significantly stronger vertebral bodies relative to their initial state(P
