Charcot's finger: not to be forgotten

Charcot joint disease or neuropathic arthropathy is a destructive arthropathy associated with diseases of the central nervous system. Diabetic neuropathy is the most common cause and largely affects the tarsal or ankle joints. Upper limb involvement is rare and there is only one well-described report of diabetic neuropathy of the digit in the literature. We present a case of Charcot arthropathy of the proximal interphalangeal joint of the ring finger secondary to diabetes mellitus.
