Understanding and Managing Dupuytren’s Contracture

Have you noticed lumps or thickening skin on your palm? Are one or more of your fingers starting to bend inwards, making it difficult to flatten your hand? If so, you might be experiencing Dupuytren’s contracture, also commonly referred to as Dupuytren’s disease. While the name might sound complex, it describes a relatively common condition affecting the hands, particularly in middle age and beyond.

This condition progresses slowly, often over years, but can eventually impact your ability to perform everyday tasks. The good news is that while there’s currently no cure, various treatments can help manage the symptoms and maintain hand function. This article will guide you through what Dupuytren’s contracture is, its symptoms, causes, risk factors, and the available treatment options.

What Exactly is Dupuytren’s Contracture?

Dupuytren’s contracture is a condition affecting the layer of tissue just beneath the skin of your palm, known as the palmar fascia. This connective tissue helps anchor the skin, but in people with Dupuytren’s, it undergoes changes.

Here’s what happens:

1. Thickening: The condition usually starts subtly, with a thickening of the skin on the palm.
2. Nodules: Small, often painless lumps or nodules may develop under the skin. These nodules are clumps of the affected fascia tissue.
3. Cords: Over time (months or years), these nodules can thicken and connect, forming tough bands or cords that extend up towards the fingers.
4. Contracture: These cords gradually tighten and shorten. As they pull on the fingers, they cause one or more fingers (most commonly the ring and little fingers) to bend inwards towards the palm. This bent position is the ‘contracture’ part of the name.

It becomes difficult, and eventually impossible, to fully straighten the affected fingers. This can interfere with simple actions like shaking hands, washing your face, wearing gloves, or placing your hand flat on a surface.

Recognizing the Signs: Symptoms and Early Stages

Dupuytren’s contracture typically progresses slowly. Recognizing the early stages is key to understanding the condition, although treatment isn’t always necessary immediately.

Early Symptoms:

• Thickening Skin: You might first notice areas of thickened skin on your palm.
• Lumps and Nodules: Small, firm lumps (nodules) may appear in the palm, usually near the base of the ring or little finger. These are generally not painful but can be tender initially.
• Pits or Dimples: Small depressions or pits might form in the skin of the palm as the tissue underneath begins to change.

Progression:

• Cord Formation: As the condition advances, the nodules can develop into hard cords that feel like strings running from the palm towards the fingers.
• Finger Bending: The hallmark symptom is the gradual bending of one or more fingers towards the palm. This contracture typically affects the joint closest to the palm (metacarpophalangeal or MCP joint) and the middle joint of the finger (proximal interphalangeal or PIP joint).
• Reduced Hand Function: As the bending worsens, it can significantly impact your ability to use your hand for everyday tasks. Difficulty gripping objects, putting hands in pockets, or performing fine motor tasks becomes more common.

A simple self-check often mentioned is the “tabletop test.” If you can’t place your palm completely flat on a table, it might indicate a contracture that requires medical evaluation.

It’s important to note that the severity and rate of progression vary significantly between individuals. Some people only ever develop small lumps, while others experience severe bending relatively quickly.

Understanding the Causes and Risk Factors

While the exact trigger for the changes in the palmar fascia isn’t fully understood, research points towards a combination of factors that increase the likelihood of developing Dupuytren’s contracture.

Key Risk Factors:

• Genetics/Ancestry: Dupuytren’s contracture often runs in families, suggesting a strong genetic predisposition. It is significantly more common in people of Northern European descent (English, Irish, Scottish, French, Dutch, Scandinavian).
• Age: The likelihood of developing the condition increases with age, typically appearing after the age of 50.
• Sex: Men are more likely to develop Dupuytren’s than women and tend to experience more severe contractures.
• Family History: Having close relatives with the condition significantly increases your risk.
• Lifestyle Factors:
  • Smoking: Tobacco use is associated with an increased risk.
  • Alcohol Consumption: Heavy alcohol intake has also been linked to the condition.
• Medical Conditions: Certain health issues seem to increase the risk, including:
  • Diabetes
  • Epilepsy (and potentially some medications used to treat it)
• Previous Hand Trauma or Manual Labor: While less definitively proven than other factors, some studies suggest a possible link with repetitive handling of vibrating tools or previous hand injuries, though this is debated.

It’s crucial to remember that having one or more risk factors doesn’t guarantee you’ll develop Dupuytren’s contracture, and some people develop it with no obvious risk factors present. The underlying cause seems to be a complex interplay between genetic susceptibility and potential environmental or health triggers.

Navigating Diagnosis and Treatment Options

If you suspect you have Dupuytren’s contracture, consulting your GP or a hand surgeon is the first step.

Diagnosis:

Diagnosis is usually straightforward and based on:

• Medical History: Discussing your symptoms, their progression, family history, and any relevant risk factors.
• Physical Examination: Your doctor will examine your hand and fingers, feeling for nodules and cords, checking the skin, and assessing the degree of contracture and your range of motion. The tabletop test might be performed. Imaging tests like X-rays are generally not needed unless other conditions are suspected.

Treatment Approaches:

Treatment for Dupuytren’s contracture aims to improve finger motion and hand function, particularly when the contracture interferes with daily life. There is no cure to stop the underlying disease process completely, and the condition can sometimes recur even after successful treatment.

Treatment choice depends on the severity of the contracture and its impact on your life.

• Observation: If the condition is mild, with only nodules or minimal bending that doesn’t affect function, your doctor might recommend monitoring the situation without active treatment.
• Non-Surgical Treatments: These are often considered for moderate contractures or for patients who prefer to avoid or are unsuitable for surgery.
  • Needle Fasciotomy (or Needle Aponeurotomy): This minimally invasive procedure is often done under local anaesthetic. A hand surgeon uses the tip of a hypodermic needle to make small tears in the tight cord, weakening it until the finger can be manipulated and straightened. Recovery is typically quick.
  • Collagenase Injection: This involves injecting an enzyme (collagenase) directly into the Dupuytren’s cord. The enzyme works to dissolve and weaken the collagen fibers in the cord over 24-72 hours. Following the injection, the doctor manipulates the finger to break the cord and straighten it. Swelling, bruising, and temporary pain at the injection site are common.
• Surgical Treatments: Surgery is often recommended for more severe contractures or when non-surgical options are not suitable or have failed. The goal is to remove the diseased fascia tissue.
  • Fasciectomy: This is the most common surgery. The surgeon makes incisions in the palm and/or finger to remove the thickened cords and diseased tissue. There are different types, such as partial palmar fasciectomy.
  • Dermofasciectomy: This involves removing both the diseased fascia and the overlying skin. A skin graft (skin taken from another part of the body) is then needed to cover the area. This procedure may be used for recurrent disease or severe cases, as it might reduce the chance of the contracture returning in that specific area.

Surgery is typically performed under regional or general anaesthetic.

Managing Dupuytren’s and Life After Treatment

Whether you undergo treatment or are in the observation stage, managing Dupuytren’s contracture involves understanding the condition and potentially adapting activities.

Recovery After Treatment:

• Hand Therapy: Following procedures like collagenase injection or surgery, hand therapy with a physical or occupational therapist is often crucial. Therapy includes exercises to regain range of motion, strength, and function. Splinting may be required, especially at night, to help keep the finger straight during healing.
• Recovery Time: Recovery varies depending on the procedure. Needle fasciotomy usually has the quickest recovery, while recovery after fasciectomy can take several weeks or months, involving wound care, therapy, and gradual return to activities.

Living with Dupuytren’s:

• Recurrence: It’s important to know that Dupuytren’s contracture can return, even after successful treatment. The underlying disease process isn’t cured by current treatments. If recurrence happens, further treatment might be necessary.
• Monitoring: Regular check-ups with your doctor or hand surgeon may be advised to monitor the condition or check for recurrence after treatment.
• Adaptations: If hand function is limited, simple adaptations or assistive devices might help with daily tasks.

Key Takeaways

Dupuytren’s contracture is a progressive hand condition characterized by thickening tissue (palmar fascia) that forms nodules and cords, eventually causing fingers to bend towards the palm.

• Symptoms: Start with palm thickening, lumps (nodules), and progress to cords and finger bending (contracture).
• Risk Factors: Include genetics (especially Northern European descent), increasing age, male sex, family history, smoking, alcohol use, and conditions like diabetes.
• Diagnosis: Based on physical examination of the hand.
• Treatment: Ranges from observation to non-surgical options like needle fasciotomy and collagenase injection, and surgical removal of diseased tissue (fasciectomy). Treatment aims to improve function when the contracture interferes with daily life.
• Management: Often involves hand therapy post-treatment and understanding that recurrence is possible.

If you notice symptoms of Dupuytren’s contracture, seeking medical advice is essential for accurate diagnosis and discussing appropriate management or treatment options to maintain the best possible hand function.
