An Overview of Facet Injections for Pain Management
1. Facet injections are the most common procedure by pain
management doctors in Arizona. There are 2 reasons to do
a facet injection. Number one is for a diagnostic reason to
figure out if the joint is causing pain, and the second
reason is for therapeutic reasons. Thankfully these often
occur together, meaning a diagnostic injection, if it works,
will give pain relief often for months.
2. In the human skeleton, there are facet joints bilaterally at
every spinal level from the neck all the way down to the
sacrum. These joints all contribute to the extreme ranges
of motion possible for patients.
3. Like all articulating body joints, facet joints may end up
with arthritis. Since there are so many, too often it occurs
at multiple levels. It is called facet syndrome if it ends up
causing pain in a person.
4. If the person is deemed to have facet related pain, an AZ
pain center doctor will typically do a diagnostic injection.
This is performed with numbing agent and cortisone
either right into the joint or around it. If it helps, then it is
great diagnostically as it tells the doctor the facet joint
was in fact leading to the pain. A medial branch block is
when the shot goes around the joint and helps pain by
numbing the sensory nerves bringing pain in, and this may
also give months of pain relief.
5. If the pain comes back a while after the facet injections, a
radio frequency ablation may help a lot. This involves
heating up the joint area and killing the small little nerve
endings causing pain. It may last 18 months or so, then the
little nerve endings may grow back. Then it may be simply
repeated to give extended relief again.
6. Whether or not facet syndrome is a real entity is debated.
Also it is not clear cut whether facet injections should be
done themselves for therapeutic reasons or simply
diagnostically to see if an RF ablation is in order. Facet
injections are typically approved for diagnostic reasons.
7. Surgery for facet arthritis in several joints is not a great
idea, so seeking treatment from an Arizona pain
management doctor to receive treatment with either a
diagnostic injection for therapeutic injection and
potentially even a radiofrequency ablation may be able to
offer substantial pain relief and decrease a person's need
for opiate medications.
