Difference between vertebroplasty and kyphoplasty

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.
