[Diabetic osteoarthropathy].

It is well-known that osteoarthropathy is one of common problems in diabetic patients. Limitation of joint mobility and painful disorder associated with inflammation of tendons and sheaths are more frequently observed on hands and shoulders. Most of these complications are not specific for diabetes mellitus, but more often in diabetic populations than in non-diabetic populations. On the other hand, destructive bone change due to diabetic polyneuropathy are commonly observed on lower extremities. To control neuroarthropathy is important for prevention of the following diabetic ulcer and gangrene. Because diabetic osteoarthropathy is mostly irreversible, early diagnosis is necessary to prevent its progression.
