Bone Augmentation (Vertebroplasty, Kyphoplasty, Saccroplasty)

What is bone augmentation?

Bone augmentation techniques aim to stabilize a weakened or a fractured bone. These minimally invasive techniques include injection of bone cement designed for this purpose, the insertion of metallic rods or screws, or a combination of both techniques, depending on the location and on the type of fracture.

How does the procedure work?

The interventional radiologist will use image guidance to precisely insert the devices used to reinforce a weakened or fractured bone.

Why perform it?

Percutaneous image-guided bone fixation is performed to stabilize a weakened bone. The procedure is a minimally invasive alternative to conventional surgery and it may be recommended to treat a range of conditions, including bone metastases, osteoporotic fractures or fractures caused by trauma.

What are the risks?

Placing needles inside bone carries the risk of bleeding and infection. In rare cases, the surrounding structures such as nerves or vessels are damaged. Occasionally, optimal stabilization cannot be achieved, which can cause a delayed fracture to another bone. You are especially at risk for this if you have advanced bone cancer.
