Question of the Week
In each issue of the Myeloma Minute, we feature an important question that has been recently addressed to the IMF Hotline. Our answers are not intended as medical advice, but as information to discuss with your doctor. If you have further questions or comments about any of the issues raised this week or in continuing weeks, please write us care of the Myeloma Minute.
Q. I have compression fractures in my back that are extremely painful. I have heard other myeloma patients mention a procedure called "kyphoplasty" that may help this problem. What can you tell me about it?
A. KYPHOPLASTY is a procedure designed to help patients who have "intractable spinal pain secondary to vertebral body fractures." In lay terms, that means pain that does not respond to bed rest, pain medications, or back braces, and is caused by breaks in the vertebrae.
The vertebrae, when fractured, often compress nerves, resulting in unremitting pain. These fractures can also cause problems in addition to pain, depending upon which vertebrae are affected. For example, when the thoracic (mid-back) spine is compressed, a patient can have decreased lung capacity. When the lumbar (lower back) spine is compressed, a patient can have decreased lung capacity and even loss of appetite due to a reduction in abdominal space. And vertebral compression often leads to significant loss of height.
Previously, the only procedure available to help support collapsed vertebrae was vertebroplasty, which involves injecting a semi-liquid plastic cement called polymethylmethacrylate (PMMA) under high pressure into a fractured vertebral body through one or two bone biopsy needles. After injection, the PMMA hardens. This technique was developed to stabilize the spine, increase mobility, and decrease the pain from vertebral compression fractures. It does not, however, help with the spinal deformity, and there is a danger of leaks of PMMA into surrounding tissues.
Kyphoplasty involves inserting (under image guidance, using a radiocontrast medium) two balloons, one in either side of the vertebral space. The balloons are then inflated. By inflating the balloons, the surgeon forces the "cancellous" or soft, central part of the bone outwards toward the outside of the vertebral body. The balloons used in kyphoplasty allow some correction of the deformity by reexpanding the compressed vertebra. The expansion of the balloons also forces the soft, central bone tissue out toward the harder, outer bone of the vertebra, where it "dams up" the cracks and fissures in the fractured vertebra. The balloon is deflated and withdrawn after it is inflated, leaving a void or cavity. PMMA is then inserted into the cavity under low pressure. Because the walls of the vertebra are dammed up, the placement of the cement is more carefully controlled than in vertebroplasty, and the cement is therefore less likely to ooze out. With kyphoplasty, surgeons are, in many cases, able to restore a good portion of a patient's lost height. This depends largely on the state of the fractured bone tissue and how much time has passed since the fracture.
In order to determine if kyphoplasty would be an appropriate option for you, you should speak to your oncologist, who may refer you to an orthopedic surgeon or a neurosurgeon. Kyphoplasty requires specially trained surgeons. If your oncologist thinks that kyphoplasty may be a viable option but doesn't have a referral for you, you may call us here at the Hotline?(800) 452-CURE (800-452-2873) in the US and Canada between 9 am and 4 pm PST; elsewhere call (818) 487-7455?or go to the Kyphon website (www.kyphon.com). This website lists specially trained surgeons by area and zip code.
What's New in Myeloma Research:
If you would like to browse trials currently open for enrollment, visit the Clinical Trials page of the IMF web site. Among the links, you will find CenterWatch and EmergingMed. The IMF has entered into partnerships with them to assist you in matching trials to your particular patient profile (i.e., stage of disease, previous treatment, how well you are able to carry out the activities of daily living, etc.) and by doing so, increase your chances of being eligible. You can also learn more about clinical trials by reviewing material from the National Cancer Institute.
If you are interested in joining a support group, use the IMF's worldwide support group directory to find one that meets near you. You can also join our online support group.
If you have a topic of particular interest that you would like us to feature, if you are starting a support group, or if you are in a support group that is doing something to make a real difference in the lives of mutiple myeloma patients and their families and friends, let us know.
