Charcot Foot
Pronunciation: shar-KOH foot
A progressive neuropathic condition causing bone and joint destruction in the foot and ankle, resulting in severe deformity that often requires custom orthotic or total contact cast management.
Full Definition
Charcot foot (also called Charcot neuroarthropathy or Charcot arthropathy) occurs most commonly as a complication of diabetic peripheral neuropathy, in which loss of protective sensation allows repeated micro-trauma to destroy the structural integrity of foot and ankle bones. The resulting collapse produces a characteristic 'rocker-bottom' deformity and dramatically increases pressure ulcer risk. In orthotic practice, Charcot foot is a key indication for accommodative devices, custom Charcot restraint orthotic walkers (CROWs), and total contact casts. Editors must render the eponym with a capital 'C' and must distinguish Charcot foot from simple diabetic neuropathy, which does not necessarily involve bone destruction.
Usage
Usage note: Always capitalise 'Charcot'. Do not confuse with Charcot–Marie–Tooth disease, which is a hereditary peripheral neuropathy, not an osteoarticular condition of the foot.
