The Amputation Prevention Center has started a monthly newsletter. Each
month we will post useful infromation in Technology, Surgery, Research,
and Education in Amputation Prevention.
This month: What is Charcot, Risks for ulceration in Diabetics, Prevention
of Diabetes related complications, and test your knowledge with a short quiz. (please click the link to view our full news letter)
What is Charcot!
A Charcot foot, pronouced “Shark-o”, is an abnormal process
that is commonly seen in people that have neuropathy. Neuropathy typically
involves a loss in sensation in the feet. Many times a fracture or dislocation
can occur with minimal trauma. Sometimes it may be related to a single
event or from repetition. Despite injury diabetics will continue to walk
because of their neuropathy. Typical findings include edema, warmth, and
bounding pulses. In the early phases there may not be any radiographic
findings." Charcot can involve multiple joints in the foot and can
result in a deformity. The best treatment is early recognition and immobilization.
It is estimated that the incidence of acute Charcot in the opposite extremity
may be as high as 25 percent. ".
Risk for ulceration in diabetic
Category 1: If you lack sensation and have no deformity, then you have a 1.7 times
more likely to develop an ulcer. "
Category 2: If you lack sensation and have deformity, then you have a 12.1 times more
likely to develop an ulcer."
Category 3: If you have had a prior ulceration, amputation, or foot deformity then
you have 36 times more likely to develop an ulceration."
