The goals of a
kyphoplasty surgical procedure
are designed to stop the pain caused by a
to stabilize the bone, and to restore some or all of the
lost vertebral body height due to the compression
kyphoplasty, a small incision is made in the back
through which the doctor places a narrow tube. Using
fluoroscopy to guide it to the correct position, the
tube creates a path through the back into the fractured
area through the pedicle of the involved vertebrae.
1 - Using
X-ray images, the doctor inserts a special balloon
through the tube and into the vertebrae, then gently and
carefully inflates it. As the balloon inflates, it
elevates the fracture, returning the pieces to a more
normal position. It also compacts the soft inner bone to
create a cavity inside the vertebrae.
2 - The
balloon is removed and the doctor uses specially
designed instruments under low pressure to fill the
cavity with a cement-like material called
polymethylmethacrylate (PMMA). After being injected, the
pasty material hardens quickly, stabilizing the bone.
