About Dupuytren Contracture

Overview

Dupuytren contracture is a hand deformity characterized by the inability to fully straighten one or more fingers. It occurs due to the shortening and thickening of connective tissues in the hand, including fat and fibrous tissue called fascia. This condition affects the mobility of the affected fingers, limiting their range of motion to bent positions. Dupuytren contracture is a progressive disorder that primarily affects individuals over the age of 50, with men being more commonly affected than women. It can occur in both hands, although it often starts in one hand initially. The severity of Dupuytren contracture can vary, making it challenging for individuals to perform manual tasks such as writing or preparing food. While the exact cause is unknown, it is believed to have a genetic component and may be associated with certain risk factors such as northern European descent.

Causes and Risk Factors

The causes of Dupuytren contracture are not fully understood, but there are several factors that may contribute to its development. Changes in certain genes involved in cell signalling pathways are thought to play a role. These genetic changes can lead to abnormal proliferation and differentiation of fibroblast cells in the connective tissue, resulting in the formation of excess myofibroblasts and the production of excess type III collagen. This abnormal contraction and excess collagen cause the characteristic changes seen in Dupuytren contracture.

Non-modifiable risk factors are risk factors that cannot be changed. Non modifiable risk factors for Dupuytren contracture include:

Age: Being older increases the risk.
Gender: Males are more likely to develop Dupuytren contracture.
Ethnicity: People with Scandinavian or Northern European background have a higher risk.
Family history: Having a family history of Dupuytren contracture increases the risk.

Modifiable risk factors are risk factors that can be changed or influenced. Modifiable risk factors for Dupuytren contracture include:

History of type 2 diabetes
Excessive alcohol intake
Smoking
Medications for seizures

It's important to note that these factors may increase the likelihood of developing Dupuytren contracture, but they do not guarantee its occurrence. If you have concerns or symptoms related to this condition, it is best to consult with a healthcare professional for an accurate diagnosis and appropriate management.

Symptoms

The most common early symptoms of Dupuytren contracture include:

Tender lump in the palm
Mild pain in the affected area
Development of tough bands of tissue in the hand
Skin puckering over the lumps or dimples
Inability to fully extend one or more fingers
Hand deformity with fingers bending toward the palm
Reduced range of motion in the affected hand(s)
Difficulty performing manual tasks, such as gripping objects

It's important to note that Dupuytren contracture can affect one or both hands, and in rare cases, it may also affect the toes or penis. If you experience any of these symptoms, it's recommended to consult with a healthcare professional for an accurate diagnosis and appropriate treatment options.

Diagnosis

To diagnose Dupuytren contracture, healthcare providers commonly perform the following examinations, tests, and procedures:

Physical exam: During this exam, the healthcare provider will look for physical signs of Dupuytren contracture, such as pain, swelling, thickened skin, bent fingers, lumps, or nodules. They may also ask you to do a tabletop test to assess hand flexibility.
Lab tests: Your healthcare provider may order lab tests to check a sample of your blood, urine, or body tissues. The specific tests ordered will depend on your symptoms and the diseases being considered.
Imaging studies: Diagnostic imaging studies may be suggested by your doctor to help diagnose or manage Dupuytren contracture. These studies allow doctors to look inside your body for clues. The type of imaging study chosen depends on your symptoms and the part of the body being examined.

To determine the stage or severity of Dupuytren contracture, additional examinations, tests, and procedures may include:

Detailed physical examination: This may involve assessing the extent of finger contractures, identifying any skin changes or deformities, and evaluating hand function.
Range of motion assessment: Healthcare providers may measure and evaluate the range of motion in your affected fingers and hand.
Hand function tests: These tests assess how well you can perform specific hand movements and tasks.

It's important to consult with your healthcare provider to determine which examinations, tests, and procedures are appropriate for your individual situation.

Treatment Options

The goals of treatment for Dupuytren's contracture are to improve hand function and reduce pain. Here are the different treatment options and how they work towards achieving these goals:

Medications:

Steroid injections: Injecting corticosteroids into the affected area can help relieve pain and inflammation and may slow down the progression of the condition.

Therapies:

Radiotherapy: This treatment uses high-energy radiation to help slow down the growth of fibrous tissue in the hand.

Therapeutic procedures:

Enzyme injections (collagenase clostridium histolyticum): These injections weaken the cords of fibrous tissue, allowing the fingers to straighten and improve hand mobility.
Needle aponeurotomy: This procedure involves using a needle to break and release the tight bands of tissue, allowing the fingers to straighten.
Open fasciectomy: Surgery to remove the thickened tissue from the palm can relieve pain and restore hand function. In severe cases, more extensive surgery may be required.

It's important to note that treatment outcomes can vary, and recurrence of Dupuytren's contracture is possible after any of these treatments. Consult with your healthcare professional to determine the best treatment approach for your individual situation.
