What is the difference between vertebroplasty and kyphoplasty?
The key difference is that vertebroplasty is used to treat vertebral body compression fractures by directly instilling cement via a thin needle cannula into the fracture under high pressure, while kyphoplasty first uses a balloon catheter at the site of the fracture to actively restore the lost vertebral body height, followed by the direct instillation of cement under lower pressure than vertebroplasty.
