"Norwegian disease" is a colloquial term sometimes used to refer to Dupuytren's contracture.
Here's a breakdown:
Dupuytren's Contracture Explained
Dupuytren's contracture, also known as Dupuytren's disease, Morbus Dupuytren, Viking disease, palmar fibromatosis, or Celtic hand, is a condition that affects the connective tissue (fascia) in the palm of the hand. This causes a thickening and tightening of the tissue, which can lead to one or more fingers bending towards the palm and becoming difficult to straighten.
Symptoms
The primary symptom is the development of nodules (small lumps) in the palm of the hand. Over time, these nodules can form cords of tissue that pull the fingers inward. The ring finger and little finger are most commonly affected, but any finger can be involved. In severe cases, it can significantly impair hand function.
Causes and Risk Factors
The exact cause of Dupuytren's contracture is unknown, but several factors are associated with an increased risk:
- Genetics: It tends to run in families, suggesting a genetic component.
- Ancestry: It's more common in people of Northern European (Scandinavian, Celtic) descent, hence the nickname "Viking disease" or "Norwegian disease."
- Age: It typically develops after the age of 40.
- Sex: Men are more likely to be affected than women.
- Medical Conditions: Diabetes, epilepsy, and alcoholism may increase the risk.
Treatment
Treatment options vary depending on the severity of the contracture and the impact on hand function.
- Observation: In mild cases, no treatment may be necessary.
- Needle Aponeurotomy: A minimally invasive procedure where a needle is used to break the cords of tissue.
- Enzyme Injections: Injections of collagenase enzyme to dissolve the cords.
- Surgery: Surgical removal of the thickened tissue.
| Treatment | Description |
|---|---|
| Observation | Monitoring the condition without intervention. |
| Needle Aponeurotomy | Using a needle to release the contracted tissue. |
| Enzyme Injection | Injecting enzymes to dissolve the contracted tissue. |
| Surgery | Surgically removing the affected tissue. |
In summary, "Norwegian disease" is a colloquial term for Dupuytren's contracture, a hand condition common in people of Northern European descent, causing fingers to bend towards the palm.
