What is Vertebroplasty and Kyphoplasty?
Vertebroplasty and kyphoplasty are minimally invasive procedures for the treatment of painful vertebral compression fractures (VCF), which are fractures involving the vertebral bodies that make up the spinal column.
When a vertebral body fractures, the usual rectangular shape of the bone becomes compressed, causing pain. These compression fractures may involve the collapse of one or more vertebrae in the spine and are a common result of osteoporosis. Osteoporosis is a disease that results in a loss of normal bone density, mass and strength, leading to a condition in which bones become increasingly porous, and vulnerable to breaking easily. Vertebrae may also become weakened by cancer.
For a vertebroplasty, physicians use image guidance, typically fluoroscopy, to inject a cement mixture into the fractured bone through a hollow needle. During kyphoplasty, a balloon is first inserted into the fractured bone through the hollow needle to create a cavity or space. The cement is injected into the cavity once the balloon is removed.
Talk to your Sound Pain Alliance provider about whether you are a candidate for this procedure.
Image-guided, minimally invasive procedures such as vertebroplasty and kyphoplasty are most often performed by a specially trained interventional pain management specialist. A nurse will insert an (IV) line into a vein in your hand or arm to administer a sedative. This procedure may use moderate sedation. It does not require a breathing tube. However, some patients may require general anesthesia. You may be given medications to help prevent nausea and pain, and antibiotics to help prevent infection. You will be positioned lying face down for the procedure.
The area through which the hollow needle, or trocar, will be inserted will be shaved, sterilized with a cleaning solution and covered with a surgical drape. A local anesthetic is then injected into the skin and deep tissues, near the fracture. A very small skin incision is made at the site. Using x-ray guidance, the trocar is passed through the spinal muscles until its tip is precisely positioned within the fractured vertebra. In vertebroplasty, the orthopedic cement is then injected. Medical-grade cement hardens quickly, typically within 20 minutes. The trocar is removed after the cement is injected.
In kyphoplasty, the balloon tamp is first inserted through the needle and the balloon is inflated, to create a hole or cavity. The balloon is then removed and the bone cement is injected into the cavity created by the balloon. X-rays and/or a CT scan may be performed at the end of the procedure to check the distribution of the cement. Pressure is applied to prevent any bleeding and the opening in the skin is covered with a bandage. No sutures are necessary. This procedure is usually completed within one hour. It may take longer if more than one vertebral body level is being treated. Your IV line is removed before you go home.
