Abstract
A case of diabetic Charcot joint with amyotrophy was reported. 63-year-old woman with diabetes of 16 years' duration has been treated with insulin, but poorly controlled. For 3 years prior to this admission, she had developed increasing weakness of both legs and wasting of proximal muscles. Four months before admission she noticed the swelling of the left foot, two months later an ulceration developed on the tip of the left fourth toe.
On examination, proximal muscle atrophy were prominent. EMG revealed myogenic changes in proximal muscle. Histology of quadriceps showed scatterd atrophy. Marked swelling with moist ulcer on the tip of the left fourth toe was observed. X-ray film revealed marked destruction of articular surface as evidenced by irregularity, sclerosing and narrowing of metatarsophalangeal joint surface involving the first, second and third toes. In the fourth toe, absorption of metatarsal bone and phalanx, suggesting of osteomyelitis was observed.
