What
are facet joints?
The
facet joints are the joints between vertebra, which are present
on each side of the spine. They provide flexibility to the spine,
which allows you to bend and turn.
Each
vertebra has two sets of facet joints. One pair faces upward (superior
articular facet) and one faces downward (inferior articular facet).
There is one joint on each side (right and left). Facet joints are
hinge-like and link vertebra together. They are located in the back
of the spine.
Facet
joints are synovial joints. This means each joint is surrounded
by a capsule of connective tissue and produces a fluid to nourish
and lubricate the joint. The joint surfaces are coated with cartilage
allowing the joints to move or glide smoothly against each other.

What
is a facet joint injection?
A
facet joint injection is an injection that is performed to confirm
that a facet joint is the source of pain. Each facet joint is supplied
by two nerves. A facet joint block can be performed by injecting
into the joint or injecting close to the nerves supplying the joint.
An injection into the joint is called an intra-articular injection
whereas blocking the nerves is called medial branch blocks or facet
joint nerve blocks. The injection will decrease pain and inflammation
in a facet joint or joints.

What
happens during the procedure?
A
facet joint injection is an in-office procedure. The physician generally
sedates the patient. The patient is positioned on the stomach. The
skin on the back is prepped and draped. Following this, the skin
is numbed with a small amount of local anesthetic. Then, a needle
is placed through the skin and advanced under fluoroscopic (x-ray)
guidance to the target site. At this time, a small mixture of numbing
medicine (local anesthetic) and an anti-inflammatory steroid is
injected. One or several joints may be blocked or they may be performed
in one region or multiple regions on one or both sides.

What
happens after the procedure?
The
patient is taken into the recovery room where they are closely monitored
for any complications or side effects. In the initial phase, a patient
is evaluated for relief with each block by performing previously
painful activities.
Occasionally,
the leg(s) may be numb for a few hours.

Post-procedure
instructions
You
were given a number of medications during the procedure. These sometimes
include sedatives, narcotics, local anesthetics, steroids and other
medications. Any of these drugs or the procedure itself sometimes
can cause side effects, including drowsiness, temporary numbness,
weakness and soreness.
What
to do after the procedure? Rest a few hours and use assistance if
needed. Resume activity as tolerated, but do not overdo it. Resume
regular diet.
Restrictions:
Do not drive or operate machinery for at least 12 hours. Do not
make important decisions for 12-24 hours after treatment. Walk with
assistance as long as numbness, weakness or drowsiness is present.
Notify
the office if you have: Excessive or abnormal bleeding, persistent
chills or fever over 100 degrees or if there is no major change
in pain pattern or level.
Emergency:
In case of emergency, call (954) 493-5048. If you are unable to
reach the physician, report to the nearest emergency room and request
them to inform the physician at Fort Lauderdale Pain Medicine.
Few
other things: Resume your usual medication(s). Apply ice as instructed.
If the IV site becomes painful, place warm towels on the site for
20 minutes, 2-3 times a day.
