Kyphoplasty is used to treat painful vertebral compression fractures in the spine, most often the result of osteoporosis. Typically, kyphoplasty is recommended after less invasive treatments, such as bed rest, a back brace or pain medication, have been ineffective. Kyphoplasty can be performed immediately in patients with problematic pain requiring hospitalization or for conditions that limit bed rest and pain medications.
Procedure
During balloon kyphoplasty no surgical incision is needed—only a small nick in the skin that does not have to be stitched. The fractured vertebra is accessed through the nick in the patient’s back. A narrow Jamshidi needle is used to create a channel through which one or two balloon-like devices (inflatable bone tamps) can be inserted into the medullary space.
The inflatable tamp is positioned in the vertebral body and filled with a radiopaque contrast medium for visualisation. The balloon is slowly inflated until the normal height of the vertebral body is restored. The balloon is then deflated and the cavity created filled with cement at a low pressure.
