A neuroarthropathy joint (also known as Charcot joint, Charcot foot or a Charcot) is a rare but potentially devastating complication of diabetes. Because diabetes is becoming more common, it is likely to be encountered more frequently. However, in order to not miss the diagnosis, Charcot needs to be considered whenever someone with diabetes presents with a hot swollen foot. The treatment for a Charcot foot is immobilisation, ideally in a below-knee, non-removable plaster cast (where available) or in a removable below-knee walking boot. The ongoing management should be by a multidisciplinary specialist team with experience looking after the diabetic foot and should include optimisation of modifiable risk factors.
