Charcot Joint
Pronunciation: shar-KOH joint
A rapidly destructive joint arthropathy associated with loss of sensation, typically seen in diabetic neuropathy.
Full Definition
Charcot joint, also known as neuropathic arthropathy, is a rapidly progressive destructive joint condition that occurs in patients with peripheral neuropathy, most commonly associated with diabetes mellitus. Named after French neurologist Jean-Martin Charcot, this condition results from loss of protective sensation leading to repetitive trauma and joint destruction. The process typically affects weight-bearing joints, particularly in the foot and ankle. Clinical presentation includes swelling, erythema, and warmth that may be mistaken for infection. Early recognition and immobilization are crucial to prevent further destruction and deformity.
Usage
Usage note: Named after Jean-Martin Charcot; capitalize as eponym. Often confused with infectious processes due to similar presentation.
