Dupuytren’s Contracture: Causes, Symptoms, Treatment
Table of Contents
Introduction
Dupuytren’s contracture is a benign, progressive disorder that affects the hands, causing the fingers to bend and making it difficult to straighten them completely. This condition is characterized by the thickening and tightening of the connective tissue in the palm, known as the palmar fascia. Dupuytren’s contracture typically progresses slowly over several years and is more common in individuals of Northern European descent.
Symptoms
The primary symptoms of Dupuytren’s contracture include:
- Painless lumps or nodules in the palm
- Pits and puckering of the skin
- Cord-like structures that cause the fingers to bend inward
- Decreased grip strength and hand functionality
As the disease progresses, the contracture can become severe, limiting the range of motion and mobility of the affected fingers.
Causes and Risk Factors
The exact cause of Dupuytren’s contracture remains unknown, but several factors may contribute to its development:
- Genetic predisposition, with a strong family history being a significant risk factor [1]
- Age and gender, as the condition is more common in older males
- Associated conditions such as diabetes, epilepsy, and alcoholic cirrhosis [2]
- Lifestyle factors, including alcohol consumption and smoking
Diagnosis
Dupuytren’s contracture is typically diagnosed through a clinical examination, during which the physician assesses the presence of nodules, cords, and the degree of contracture. In some cases, imaging tests such as ultrasound or MRI may be used to evaluate the extent of the condition.
Treatment
Treatment options for Dupuytren’s contracture depend on the severity and progression of the disease. Non-surgical treatments include:
- Physical therapy and stretching exercises
- Steroid injections to reduce inflammation
- Collagenase injections (Xiaflex) to break down the collagen in the cords [3]
For more advanced stages, surgical interventions may be necessary:
- Fasci ectomy: Removal of the affected fascia
- Dermofasci ectomy: Removal of the affected fascia and overlying skin
- Needle aponeurotomy: Division of the cords using a needle
Prognosis
The prognosis for Dupuytren’s contracture varies, as the condition can recur even after successful treatment. Proper post-treatment care, including physical therapy and splinting, can help maintain hand function and minimize the risk of recurrence.
