Vertebroplasty
What causes vertebral fractures?
The spine is made up of bones called vertebrae that are linked together. When
these bones become weakened, one or more can break and start to flatten out.
This is known as a compression fracture.
Osteoporosis is the leading cause of vertebral fracture. Osteoporosis is a disease
in which the density and quality of bone are reduced, leading to weakness of
the skeleton and increased risk of fracture, particularly of the spine, wrist,
hip, pelvis and upper arm. In many affected people, bone loss is gradual and
without symptoms or warning signs until the disease is advanced. When osteoporosis
becomes severe, the vertebrae can easily fracture. Minor events such as coughing
or sneezing may result in a fracture. Such fractures may go undiagnosed because
the patient does not realize that his back pain may be due to a fracture.
What is vertebroplasty?
Vertebroplasty is a minimally invasive procedure involving injection of a cement
into the fractured vertebral body to repair and strengthen the vertebra, prevent
future fractures, and alleviate back pain.
How is vertebroplasty performed?
Prior to the vertebroplasty procedure, you will need to have a CT scan and/or
MRI scan to confirm that you are a candidate for the procedure. Vertebroplasty
is most effective on recent fractures, but is not effective on older fractures.
You will also need to have blood drawn at the hospital or a local clinic to
ensure that you do not have any blood clotting problems that may result in bleeding
complications during the procedure.
The vertebroplasty in performed in the interventional radiology suite. You will
be asked to lie on your stomach on the procedure table. The nurse will give
you medication through an intravenous line in your arm to help you feel relaxed
and drowsy. The Interventional Radiologist will then numb the affected area
on your back. Using x-ray guidance, the Interventional Radiologist will advance
a needle through the skin in the back into the affected vertebra. Contrast media
(x-ray dye) is injected through the needle to see the venous drainage of the
spine and ensure adequate positioning of the needle. Once the needle is properly
positioned, a cement mixture of polymethylmethacrylate (PMMA), barium powder,
tobramycin, and a solvent is slowly injected into the spine using x-ray guidance.
It takes about 10 - 20 minutes for the cement to harden. The needle is then
removed, and if necessary, the procedure may be repeated at other spinal levels.
The procedure usually takes about 1 – 1.5 hours for each vertebra injected.
After the procedure, you will be taken to the recovery room and will stay in
bed for 4 hours to allow the cement harden completely. Most patients go home
the same day and receive a prescription for pain medication. Before you leave,
the nurse will give you written instructions regarding care of the affected
area.
Some patients experience immediate pain relief after the procedure. Most report
that their pain is gone or significantly better within 48 hours. Many people
can immediately resume their normal daily activities.
Discharge and Follow-Up Appointment Instructions
• You should rest for the remainder of the day and limit activity for
the next 24 hours
• You may resume your normal diet
• You may drive 24 hours after discharge
• Take medications as directed. If you receive medications following the
vertebroplasty that may make you feel drowsy, you should not:
-Operate a motor vehicle, machinery, or power tools
-Drink any alcoholic beverages
-Make important decisions, such as to sign any legal papers
-Perform any activity that requires physical coordination or mental alertness
-Take any additional sedatives
• Gradually decrease pain medication to take only as needed
• Remove bandage after 24 hours and clean area with soap and water
• After 24 hours, you may shower or bathe
• Observe the site for infection (redness, swelling, drainage, warmth)
• You may experience new back and hip discomfort due to an increased ability
to move. Gradually increase your level of activity over the next few days.
• Walking is encouraged
• Do not lift anything heavier than a gallon of milk
• Do not do any heavy lifting for 3 months. Then gradually increase your
lifting to normal.
• Immediately report the following symptoms or go directly to
the emergency room:
Chest pain
Shortness of breath
Leg weakness or numbness
Severe back pain – if it is new
Unexplained fever
Schedule a 4 week post procedure follow up appointment with the Interventional
Radiologist. Call the office at (305) 932-7800 to schedule the appointment.
