What is Vertebroplasty?
Vertebroplasty is an image-guided, minimally invasive,
nonsurgical therapy used to strengthen a broken vertebra
(spinal bone) that has been weakened by osteoporosis
or, less commonly, cancer. Vertebroplasty can increase
the patient’s functional abilities, allow a
return to the previous level of activity, and prevent
further vertebral collapse. It is usually successful
at alleviating the pain caused by a compression fracture.
Often performed on an outpatient basis, vertebroplasty
is accomplished by injecting an orthopedic cement
mixture through a needle into the fractured bone.
What are some common uses of the procedure?
Vertebroplasty is used to treat pain caused by osteoporotic
compression fractures. After menopause, women are
especially vulnerable to bone loss. More than one
fourth of women over age 65 will develop a vertebral
fracture due to osteoporosis. Older people suffering
from compression fractures tend to become less mobile,
and decreased mobility accelerates bone loss. High
doses of pain medication, especially narcotic drugs,
further limit functional ability. Vertebroplasty is
often performed on patients too elderly or frail to
tolerate open spinal surgery, or with bones too weak
for surgical spinal repair. Patients with vertebral
damage due to a malignant tumor may sometimes benefit
from vertebroplasty. In rare cases, it can be used
in younger patients whose osteoporosis is caused by
long-term steroid treatment or a metabolic disorder.
Typically, vertebroplasty is recommended after simpler
treatments, such as bedrest, a back brace or pain
medication, have been ineffective, or once medications
have begun to cause other problems, such as stomach
ulcers.
How should I prepare for the procedure?
First, you’ll be clinically evaluated. The evaluation
generally includes diagnostic imaging, blood tests
and a physical exam. Diagnostic imaging such as spine
x-rays, a radioisotope bone scan or magnetic resonance
(MR) imaging will be done to confirm the presence
of a compression fracture that is amenable to vertebroplasty.
If an MR cannot be performed, because of a pacemaker
or other medical factor, a CT scan can be substituted.
In preparation for the clinical evaluation and physical
exam, you should obtain and bring with you any previous
diagnostic images, especially x-rays or MR films.
Be sure to tell your doctor if you are allergic to
x-ray contrast material, which contains iodine. Most
medical facilities provide patients with preprocedure
instructions. Instructions will typically tell you
not to eat for at least six hours before the procedure.
If you are diabetic, you should contact your doctor
for instructions on regulating your blood sugar and
medications. On the day of the procedure, if your
doctor instructs you to take your usual medications,
swallow your medication with sips of water or clear
liquid up to three hours before the procedure. Avoid
drinking orange juice, cream and milk.
If you take an anticoagulation medication (blood
thinners such as Coumadin), you will have to stop
the treatment until coagulation becomes normal, usually
within three to five days. Contact your doctor before
stopping any medication to determine if it is safe
for you. On the day of the procedure, patients who
use blood thinners should report to the hospital a
little earlier for a blood test to verify that their
anticoagulant has stopped working. If you are unable
to interrupt your anticoagulant regimen, a short in-patient
stay for intravenous treatment with heparin may be
required. All patients should arrange for an adult
to drive them home after the procedure.
