[Exceptional diabetic arthropathy of the foot (author's transl)].

The osteopathy of the foot is a rare complication of diabetes mellitus. It is seen in the distal parts mostly. The arthropathy ("Charcot-joint") is even more rare, and is regularly combined with a neuropathy. The roentgen signs of the "diabetic foot" are demonstrated, as there are osteoporosis, iuxta-articular cortical defects, osteolysis of the bone ends, bone destruction and reconstruction, periost reaction and sklerosis of the bone shafts.
