Suspect acute Charcot foot in a patient with diabetes and neuropathy who presents with a swollen warm foot
If acute Charcot foot is suspected, arrange for offloading of the foot (to minimise further damage) and refer to a specialist foot clinic immediately
Plain radiographs may be normal in the early stages of the disease
Magnetic resonance imaging should be considered when the suspicion of acute Charcot foot is high
A 38 year old man was referred by his general practitioner to our diabetes foot clinic with a swollen red foot (fig 1⇓). He had had type 1 diabetes for 25 years, complicated with retinopathy, peripheral neuropathy, and nephropathy, and was being worked up for dialysis following a failed pancreas-kidney transplant. The absence of pain together with preserved pulses and intact skin raised a suspicion of acute Charcot foot. A plain radiograph of the foot showed fractures through the necks of the first three metatarsals (fig 2⇓).
