Facet syndrome is a condition
of the small joints in the spine (called
facets) characterized by pain and inflammation
around the joint. Shaped like miniature
hooks, facets are about the same size as
the joints in your hands. They connect each
vertebra in your spine to its neighbors,
help you bend smoothly, and prevent your
vertebrae from slipping back and forth.
Facets are lined with cartilage to allow
the bones to glide freely over each other.
Injury and arthritis can damage the cartilage,
leading to stiffness, pain, and inflammation.
Causes of Facet Syndrome
Twisting injuries can tear the cartilage
around the joint much the same way knee
cartilage can be torn. The torn portion
of cartilage may then form a barrier in
the joint, limiting motion and causing pain
when pressure is applied to the joint. Facet
joints are vulnerable to arthritis, which
has been caused by previous injury to the
joints or by the normal wear and tear of
aging. Discs that have degenerated also
can cause irritation around the facet joints.
Motions that require repeated extensions
(bending over with straight legs, driving
with your seat far from the wheel, or standing
in one position too long) will overload
the facet joints and cause inflammation,
swelling and pain.
Diagnosis
Your doctor may order one or more special
tests to help confirm your diagnosis, rule
out other problems, and pinpoint the source
of your back pain.
X-rays show the general condition of your
vertebrae (bones), and are very helpful
in determining the cause of pain. Although
x-rays cannot reveal a ruptured disc, for
instance, they may reveal a narrowed disc
space which can be an indication of trouble
in that area of the spine.
MRIs (magnetic resonance imaging) and CTs
(computerized tomography) produce detailed
computer images of soft tissues and bones.
MRIs are especially beneficial for the study
of soft-tissue abnormalities such as disc
degeneration, protrusion, or rupture. CT
scans give a cross-section view of the spine
and can show a bulging or ruptured disc.
EMGs (electromyography) measure the electrical
activity of your muscles’ contractions.
They detect nerve or muscle irritation and
damage.
Bone scans can reveal abnormal bone activity.
Treatment
Initial treatment is conservative and usually
includes up to four weeks of bedrest followed
by a gradual return to normal activities.
During this time, you may receive medications
such as anti-inflammatory agents, muscle
relaxants, and physical therapy. For many,
this is sufficient to treat the symptoms,
however for those whom conservative therapy
has not worked, spinal injection therapy
may be appropriate.
- Facet Injections: Facet Injections are
injections of a potent cortisone-type
drug and a Novocaine®-like anesthetic
directly into the facet joints. By getting
the cortisone to the specific site of
inflammation, better pain control and
treatment may be achieved. The addition
of anesthetic with cortisone may give
relief. The procedure may be done under
special x-ray control to help place the
medication more precisely into the problem
joint. To avoid discomfort, a local anesthetic
is used to numb the skin around the area
of the injection. Facet injections may
provide long lasting pain relief.
- Physical Therapy: Once the pain and
inflammation are under control, it is
important to restore motion and take stress
off of the facet joint. Tight muscles
often add considerably to the pain syndrome
and if not corrected, the inflammation
may return.
Physical therapy offers various methods
to keep joints flexible and help stretch
and strengthen the muscles. Tight muscles
are treated with deep heat, electrical
stimulation, and muscle-stretching exercises.
Aquatic therapy is useful, particularly
in the early stage of treatment, because
the buoyancy of the water makes it easier
to move without stress on the sensitive
joints. The water also offers steady resistance
against the body so that muscle strain
is avoided and flexibility is increased.
Exercises to strengthen muscles can provide
a stabilizing effect on your spine. Techniques
to help build a strong spine and the basics
of good body mechanics (the way you move
your body and back) are important in long-range
care and prevention of future back problems.
What else can be done?
Avoid lifting with your back bent; keep
your back straight and lift with your legs.
A proper diet is important because excess
weight around the abdomen arches the back
and leads to even more stress on the facet
joints.
