Answer

Kyphoplasty is often mentioned alongside vertebroplasty. Kyphoplasty differs from vertebroplasty by adding an important additional step: insertion and inflation of a balloon before cement delivery, which also serves to restore vertebral body height and spine alignment. [2] Kyphoplasty is often used interchangeably with vertebroplasty and is considered a subset of vertebroplasty. Spine jack is a new system that corrects vertebral height, reduces the incidence of endplate damage by inserting an implant that mechanically augments the height of the vertebral body to better restore alignment followed by injection of cement.
