When someone is first diagnosed with this disease their
first response is “charcot, like a shark”. Charcot Arthropathy, is pronounced
“shark-O” and has a French/German derivative.
What exactly is
Charcot and who does it affect?
Charcot is a degenerative process of joints in the foot and
ankle and can present in many different ways. It is a slow progressive process
and usually presents itself with bones in the foot appearing to have fractures
and dislocations. Charcot is a disease process where the joints of the foot and
ankle have bony destruction. Charcot is caused by neuropathy, or a lack of
sensation, which is primarily caused by Diabetes Mellitus. Other causes can be caused
by Alcoholism, syphilis and other causes of neuropathy.
Charcot begins slowly but as the disease progresses it can
appear similar to an infection. The joints of the foot that can are affected appear
to be red, hot, swollen, deformed and perhaps have an ulceration. There are 4
different stages of Charcot. The first being Stage 0, this is a pre Charcot
stage with minimal symptoms. Stage 1 is an acute stage, when a patient will
present with the above mentioned symptoms including a red, hot, swollen foot.
Stage 2 is the step down from Stage 1 and there is less redness, swelling
during this stage. Stage 3 is a dormant stage and happens in between attacks/
Stage 1.
How is this
diagnosed?
Diagnosis can be difficult because Stage 1 can represent
other pathologies such as infection, gout or septic arthritis. Having neuropathy
with Diabetes puts a patient with symptoms at high suspicion for Charcot. Diagnosis
can be difficult because when someone presents to their physician with these
symptoms the disease has usually been going on for a while. Diagnosis is
usually by clinical exam but x-rays, MRIs and CT scans can be taken to aid in
the diagnosis.
How is it treated?
Treatment is broken down into surgical or non-surgical
options. During the Acute Phase/Stage 1 non-surgical options are the way to
proceed. This includes a total contact cast, which is a non-weight bearing cast
and doesn’t allow the foot to touch the ground. By using an offloading device
it allows the joints to heal. This phase
of the disease can take many months and even up to a year to heal. Surgical
treatment is recommended for Stage 3, which includes foot and ankle fusions and
reconstruction. Not all patients are candidates for surgical treatment, since
there are a lot of complications and a long recovery time from these surgeries.
What are the long
term complications from this disease?
Even with early treatment and compliance this disease has
flare ups. Flare ups cannot be predicted and as the disease goes on there can
be increase bony destruction. As the disease progresses there can be a collapse
of the foot with prominent bones that appear to be “sticking out of the bottom
of the foot”. This type of foot is known
as a rocker bottom foot. At this stage certain shoes and orthotics can be
custom made to help with support of this foot.
In conclusion, Diabetic neuropathy with Charcot can have
devastating consequences for a patient. If you are a diabetic it is recommended
to see a Podiatrist every few weeks to do a diabetic foot exam. Seeing a
Podiatrist regularly can prevent some of these complications.
