Insulin-dependent diabetes mellitus is a risk factor, but the condition also occurs among otherwise healthy. In diabetes, diabetic hand syndrome is seen in 8-50%, especially after severely manageable disease over several years.
Most have had insulin-requiring diabetes mellitus for several years. Increased prevalence among those with difficult to control diabetes. The disease process results in increased connective tissue (collagen) which is not degraded. In addition, changes in small blood vessels (microangiopathy) which affects blood circulation skin and subcutaneous tissue.
- Stiffness and reduced movement of the fingers (diabetic kyaroarthropathy / chiroarthropathy)
- Hard to stretch your fingers completely
- Not particularly painful
- Gradually curving fingers
- Dupuytren's contracture
- Begins with thickening of the palm, usually within the fingers 3-5
- Trigger finger (stenosing tendovaginitis / tenosynovitis)
- Finger "locking"
- Carpal tunnel syndrome / canalis carpi syndrome
- Varying number unit and sticking out in fingers 2-4
- Charcot neuro-arthropathy (Less)
- Misalignment / bias in joints
- Algodystrophy / Reflective dystrophy (Less)
- Pain, skin and muscle changes
- Hands infections (less common)
An early research finding is that fingers cannot be stretched when the palm is placed against a table surface. Similarly, the fingers remain bent when the palms are placed against each other ("Prayers sign").
Dupuyten's contracture is often easily recognizable in the palm of your hand. Both hands need not be attacked. Blood tests, inclusive Antinuclear Factors (ANA) with subgroups (Scl70, CENP) expected to be normal.
Incorrect diagnosis (similar diseases, differential diagnoses)
Diabetic hand syndrome can be mistaken for scleroderma / systemic sclerosis. However, in diabetic hand syndrome is not expected Raynaud's phenomenon, telangiectasia, calcinosis (lime under the skin) or other facial and skin changes. Capillaroscopy is usually normal, without megapapillaries and bleeding, such as in systemic sclerosis.
The best regulation of blood sugar is preventive and can better the changes at an early stage. Stretches to stretch your fingers can have an effect. In some cases, hand surgery is necessary, but one must be aware that the complication risk of diabetes is greater than that of otherwise healthy ones that are treated for Dupuytren's contracture or trigger finger.
