Vertebroplasty and Kyphoplasty are very similar procedures. Kyphoplasty is a slight variation of vertebroplasty.
In both vertebroplasty and Kyphoplasty a large needle is placed into the broken vertebrae under x-ray guidance. Next plastic is injected into the fractured vertebrae in vertebroplasty, but in Kyphoplasty a ballon is blown up. The balloon may push the bone back into its original position (that is reduce the fracture). The balloon is then removed and plastic is injected into the cavity. Overall they are very similar procedures and have similar outcomes. Please click on Kyphoplasty for more information. Good Luck!
