Charcot foot (shar-KOH), or Charcot neuroarthropathy (noo-ro-ar-THROP-ah-thee), is a destructive disease of the bones and joints of the foot driven by the loss of protective pain sensation. When that sensation is gone, small repeated injuries go unfelt, and the bones can fracture and the joints collapse, sometimes caving the arch into a rocker-bottom shape. It is often confused with the CMT foot, but the two are entirely different: the CMT foot (cavovarus) is a high, rigid, structurally intact deformity built by muscle imbalance, while Charcot foot is bone destruction built by sensory loss. It can occur in CMT, but it is rare, and it is far more common in diabetes. It shares the CMT name only because Jean-Martin Charcot described both. Knowing the term matters mainly so it is not mistaken for the usual CMT foot: a hot, swollen foot in anyone with neuropathy deserves prompt evaluation.
When Medicine Lost Its Compass
Evidence failed not because it was wrong, but because it was weaponized. I lived the downstream effects of that failure for more than a decade. This is what happens when medicine forgets that data always ends in a human being.
