Dupuytren’s contracture is a hand deformity characterized by the progressive thickening and tightening of the connective tissue beneath the skin of the palm and fingers. This condition can limit finger movement and cause the fingers to bend towards the palm, making everyday tasks challenging. In this article, we will explore the definition of Dupuytren’s contracture, its different types, and available treatment options.

Dupuytren’s contracture is a hand deformity that affects the connective tissue beneath the skin of the palm and fingers. This condition causes the fingers to bend inward towards the palm, making it difficult to straighten or fully extend them. In this article, we will explore the definitions, types, causes, symptoms, and treatment options for Dupuytren’s contracture.

Dupuytren’s contracture is a progressive condition that primarily affects the fascia, a layer of connective tissue found beneath the skin of the palm and fingers. The fascia thickens and forms cords, which gradually contract, pulling the affected fingers toward the palm. Over time, the contracture can become severe, hindering hand function.

Types

There are two main types of Dupuytren’s contracture based on the location of the affected tissue:

Palmar Dupuytren’s contracture: This type involves the cords forming on the palm side of the hand, causing the fingers to bend downward.
Plantar Dupuytren’s contracture: Unlike the palmar type, this affects the feet, causing the toes to curl downward.
Primary Dupuytren’s Contracture: This is the most common type and typically occurs in individuals of Northern European descent. It often begins with the development of small nodules or lumps in the palm, which may later form into cords, causing finger contracture. Primary Dupuytren’s contracture is more common in men and tends to affect both hands.
Secondary Dupuytren’s Contracture: This type is associated with certain medical conditions or factors that increase the risk of developing the condition. These factors include diabetes, alcoholism, smoking, seizure disorders, and certain medications like anticonvulsants. Secondary Dupuytren’s contracture can progress more rapidly and affect younger individuals compared to the primary type.

Causes

Common causes of Dupuytren’s contracture and provide detailed explanations in simple language.

Genetic Predisposition: Dupuytren’s contracture often runs in families, indicating a genetic component. Certain gene mutations are believed to increase the risk of developing the condition.
Age: The risk of developing Dupuytren’s contracture increases with age, typically affecting individuals over 50 years old. The exact reason for this correlation is not fully understood.
Gender: Men are more likely to develop Dupuytren’s contracture than women. The condition is more prevalent in men over the age of 50, although women can also be affected.
Ancestry: Individuals of Northern European descent, particularly those of Viking or Celtic heritage, have a higher risk of developing Dupuytren’s contracture. This suggests a potential role of ethnicity in the condition.
Smoking: Smoking has been linked to an increased risk of Dupuytren’s contracture. The toxins in cigarettes may affect blood vessels and connective tissues, contributing to the development of the condition.
Alcohol Consumption: Excessive alcohol consumption has been associated with an increased risk of Dupuytren’s contracture. Alcohol abuse can lead to changes in collagen production, which may contribute to the development of the condition.
Diabetes: People with diabetes have a higher likelihood of developing Dupuytren’s contracture. The exact mechanisms linking the two conditions are not yet fully understood but may involve factors related to blood vessel health and glucose metabolism.
Liver Disease: Liver diseases, such as cirrhosis, have been associated with an increased risk of Dupuytren’s contracture. Liver dysfunction can affect collagen metabolism, potentially contributing to the development of the condition.
Epilepsy and Seizure Disorders: Certain anti-epileptic medications, such as phenytoin and phenobarbital, have been linked to an increased risk of Dupuytren’s contracture. However, the association between epilepsy itself and the condition is not well-established.
HIV Infection: Some studies have suggested an increased prevalence of Dupuytren’s contracture in individuals with HIV infection. The exact mechanisms underlying this association are still being investigated.
Thyroid Disorders: Thyroid imbalances, particularly hypothyroidism, have been linked to an increased risk of Dupuytren’s contracture. Hormonal changes associated with thyroid dysfunction may contribute to the development of the condition.
High Cholesterol: Elevated levels of cholesterol in the blood have been associated with an increased risk of Dupuytren’s contracture. Cholesterol deposits in the blood vessels may affect blood flow and contribute to the development of the condition.
Hand Injuries: Injuries to the hand, particularly repetitive trauma, have been suggested as a potential cause of Dupuytren’s contracture. However, the exact relationship between trauma and the condition is still unclear.
Vibrating Tools: Prolonged use of vibrating tools, such as power drills or jackhammers, may increase the risk of developing Dupuytren’s contracture. The continuous vibration can potentially damage the hand tissues over time.
Manual Labor: Occupations that involve repetitive hand movements or manual labor have been associated with increased

Symptoms

Common symptoms associated with this condition, explaining each one in detail to provide a comprehensive understanding.

Nodule Formation: One of the initial signs of Dupuytren’s contracture is the development of small, firm nodules under the skin of the palm. These nodules may feel tender or painless and are often the first noticeable symptom.
Finger Flexion: As Dupuytren’s contracture progresses, the affected fingers gradually become flexed, making it difficult to straighten them fully. This flexion typically starts in the ring and little fingers and may eventually involve the middle finger.
Thickening of Palm Skin: The skin in the palm may thicken and develop a characteristic puckered or dimpled appearance due to the presence of excess collagen.
Finger Curling: Affected fingers may curl or contract towards the palm, resembling a claw-like deformity. This curling can worsen over time, leading to further restriction in finger movement.
Reduced Range of Motion: Dupuytren’s contracture restricts the normal range of motion in the fingers, making it challenging to perform activities that require grasping or extending the hand fully.
Difficulty Placing Hand Flat: The progressive contracture of the palm and fingers can make it increasingly difficult to lay the hand flat on a surface, causing a noticeable inability to open the hand fully.
Skin Pits: Small pits or depressions may form on the palm’s surface due to the thickening of the underlying tissues. These pits are often painless but can be visually apparent.
Palm Cord Formation: As the disease advances, palpable cords or bands may develop in the palm. These cords can be felt as thickened, raised structures running from the base of the fingers toward the wrist.
Hand Tremors: In some cases, individuals with Dupuytren’s contracture may experience hand tremors or involuntary shaking due to the altered muscle mechanics caused by the condition.
Finger Stiffness: Stiffness in the affected fingers is a common symptom. It becomes increasingly challenging to flex or extend the fingers fully, impacting dexterity and fine motor skills.
Pain or Discomfort: While pain is not a primary symptom of Dupuytren’s contracture, some individuals may experience mild discomfort, especially when attempting to extend or use the affected fingers.
Difficulty Wearing Gloves: As the contracture progresses, wearing gloves becomes problematic due to the fingers’ limited ability to straighten, making it challenging to fit them into the glove’s fingers.
Limited Grip Strength: With progressive curling and reduced range of motion, individuals may notice a decline in grip strength, impacting their ability to perform everyday tasks that require manual dexterity.
Difficulty Handling Objects: Activities like holding utensils, writing, or grasping objects of various sizes become increasingly challenging as the fingers lose their ability to move and adapt freely.
Finger Skin Pits: Similar to the pits on the palm, small depressions or dimples may form on the skin of the affected fingers, often corresponding to the location of underlying nodules or cords.
Hand Fatigue: Individuals with Dupuytren’s contracture may experience hand fatigue more quickly than usual due to the increased effort required to compensate

Diagnosis

Diagnosis and tests for Dupuytren’s contracture in simple language.

Medical History: Your doctor will ask about your medical history, including any previous hand injuries or surgeries, family history of Dupuytren’s contracture, and other relevant information. This helps identify risk factors and potential causes.
Physical Examination: During a physical examination, the doctor will assess the affected hand and fingers for lumps, thickened cords, and the extent of finger contracture. They may also check for associated symptoms, such as dimpling or puckering of the skin.
Hand Function Assessment: The doctor may evaluate your hand function by measuring grip strength, range of motion, and dexterity. This helps determine the severity and impact of Dupuytren’s contracture on daily activities.
Angle Measurement: Using a goniometer, the doctor measures the angle of finger contracture to determine the degree of deformity. This quantifies the severity of Dupuytren’s contracture and helps plan treatment accordingly.
X-ray: X-rays are useful in ruling out other conditions and assessing joint involvement. Although Dupuytren’s contracture primarily affects the soft tissues, X-rays can reveal abnormalities in the underlying bones or joints.
Ultrasound: Ultrasound imaging uses high-frequency sound waves to create real-time images of the affected hand. It helps visualize and measure the thickness of the cords, assess disease progression, and guide treatment decisions.
Magnetic Resonance Imaging (MRI): MRI scans provide detailed images of the soft tissues in the hand, allowing for a more comprehensive assessment of the extent and severity of Dupuytren’s contracture. It helps evaluate the involvement of adjacent structures and plan surgical interventions if necessary.
Collagenase Test: Collagenase is an enzyme that breaks down collagen, the protein responsible for the formation of Dupuytren’s contracture cords. A collagenase test involves injecting a small amount of this enzyme into the contracted cord, softening and releasing the finger.
Blood Tests: Although there are no specific blood tests for Dupuytren’s contracture, certain markers of inflammation and fibrosis may be assessed to determine disease activity and monitor treatment response.
Genetic Testing: Dupuytren’s contracture has been associated with certain genetic factors. Genetic testing can help identify specific gene mutations that contribute to the development and progression of the condition, particularly in cases with a strong family history.
Dupuytren’s Severity Score: The Dupuytren’s Severity Score is a validated assessment tool that quantifies the severity of the condition based on several parameters, such as the degree of finger contracture, the number of affected joints, and the presence of nodules or cords.
Hand Function Questionnaires: Various questionnaires, such as the Michigan Hand Outcomes Questionnaire or the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, assess the impact of Dupuytren’s contracture on hand function, quality of life, and overall disability.
Photography: Taking photographs of the affected hand at regular intervals helps document disease progression and assess treatment outcomes. It provides a visual record that can be used for comparison and analysis.

Treatment

Best treatment options for your situation.

Observation and Monitoring: In cases where the contracture is mild and does not interfere significantly with hand function, observation and regular monitoring by a healthcare professional may be recommended. This approach is often employed when the condition progresses slowly or remains stable over time.
Hand Therapy: Hand therapy involves the use of exercises, stretches, and techniques to improve hand function and reduce the progression of Dupuytren’s contracture. A hand therapist can provide customized exercises and splints to help maintain hand mobility.
Needle Aponeurotomy: Also known as percutaneous needle fasciotomy, this minimally invasive procedure involves inserting a small needle into the affected tissue to divide the tight bands causing finger contracture. The procedure is typically performed under local anesthesia and may require multiple sessions.
Collagenase Injection: Collagenase injection involves injecting an enzyme into the Dupuytren’s cord, which helps break down the collagen and release the contracted finger. After injection, the hand is manipulated by the healthcare provider to facilitate cord disruption. This treatment is generally performed in a clinic setting.
Radiotherapy: Low-dose radiotherapy can be used to slow down the progression of Dupuytren’s contracture. It is most effective in the early stages of the condition and is typically administered in multiple sessions over several weeks.
Splinting: Wearing a splint can help maintain finger extension and prevent further contracture. Splinting is often used in combination with other treatments, such as hand therapy or after surgical procedures, to support the healing process.
Steroid Injections: Corticosteroid injections into the Dupuytren’s cord can help reduce inflammation and temporarily improve finger extension. This treatment is mainly used for short-term relief and is not considered a permanent solution.
Hand Exercises: Regularly performing hand exercises can help maintain hand flexibility and slow down the progression of Dupuytren’s contracture. Exercises typically involve finger stretches, hand opening and closing, and grip-strengthening activities.
Fasciotomy: Fasciotomy is a surgical procedure where the tight cords in the hand are partially or completely divided to release the contracture. It can be performed as an open procedure or endoscopically using a small incision. Hand therapy is usually recommended post-surgery to optimize hand function.
Percutaneous Fasciectomy: This minimally invasive surgery involves using a needle to cut and remove the affected tissue. It is often performed under local anesthesia, and multiple sessions may be required to achieve optimal results.
Xiaflex Injection: Xiaflex is an FDA-approved collagenase injection specifically used for the treatment of Dupuytren’s contracture. The enzyme is injected into the cord, and the hand is manipulated to disrupt the tissue, allowing for improved finger extension.
Needle Aponeurotomy Combined with Collagenase Injection: In some cases, a combination of percutaneous needle fasciotomy and collagenase injection may be used to achieve better outcomes. The needle is first used to divide the tight bands, followed by collagenase injection
