Ask the Expert: When Is the Right Time to Treat Dupuytren's Contracture?
The genetic disorder affects the palmar fascia, the thick layer of tissue found in the palm of the hand. Treatment is dependent on an individual's symptoms and quality of life.
Dupuytren's disease is a disorder that can lead to Dupuytren's contracture over time. The exact cause of Dupuytren's disease, as well as the contracture, is unknown. It is a genetic disorder, however, that is often inherited. There are many risk factors that can contribute to developing Dupuytren's disease and ultimately Dupuytren's contracture.
Dupuytren's disease is a disorder of the palmar fascia.
The palmar fascia is a thick tissue layer in the palm of the hand that protects the muscles, tendons, nerves, arteries, and veins in the hand. This tissue begins to undergo changes that lead to contractures.
The process starts with overstimulation of a pathway that regulates cell growth. Cells called fibroblasts that make up the fascia are responsible for producing proteins like collagen, which give tissues their strength and flexibility.
These cells are activated and change into myofibroblasts. These myofibroblasts produce excess collagen as they are typically activated as a stress response for tissue healing.
In Dupuytren's, however, this excessive collagen formation leads to nodules. Growing nodules form cords, which are thickened bands that can extend into the fingers. These cords pull the fingers into a fixed flexed position most commonly at the knuckles and at the middle joint (proximal interphalangeal joint).
This happens most frequently in the ring and little finger. This 'flexion contracture' can lead to difficulty gripping objects, placing the hand flat, or shaking hands.
What causes Dupuytren's contracture?
The exact cause of Dupuytren's contracture is unknown. It is a genetic disorder that is often inherited. Certain risk factors can contribute to the development of Dupuytren's disease, and, ultimately, Dupuytren's contracture.
Are there increased risk factors?
Research published in 2001 indicates Dupuytren's disease mainly affects people from Scandinavia, Great Britain, Ireland, parts of France, Germany, and the Netherlands.
It also appears to be an inheritable condition. Canadian Robert McFarlane published a preliminary report in 1985 that evaluated the family history of 812 people with DD. Findings showed that 68% were of Northern European ancestry.
Research indicates an association with Ledderhose disease which is a similar phenomenon that occurs in the foot with the plantar fascia and Peyronie's disease which affects a connective tissue layer in the penis.
There is also an association with the use of vibratory tools. For workers exposed to repetitive handling tasks or vibration, the risk of contracting Dupuytren's disease is three times higher. To date there have been no studies to prove that these tasks caused the disease — but there is an association.
Some other risk factors include:
having diabetes
smoking
alcoholism
HIV
vascular disease
How is Dupuytren's contracture diagnosed?
The diagnosis can be made by physical examination. No imaging is needed. The history of a typically painless loss of extension of the fingers is sufficient to make the diagnosis.
The presence of nodules, skin puckering, or cords can also aid in the diagnosis.
Does Dupuytren's contracture need treatment?
Without treatment, disease progression occurs in about 50% of patients. Spontaneous improvement is rare. About 10% to 15% of patients will have no progression. Roughly 70% will have gradual progression over the years leading to contractures.
Rapid progression is rare but can occur when patients present at younger ages. Therapy is palliative as there is no cure for the condition.
When does Dupuytren's contracture need treatment?
Indications for treatment are based on the effects of the disease and on the patient's quality of life. Patients who cannot fully flatten their hand against a table (positive tabletop test) and those with a flexion of about 30° at the knuckle or 15° to 20° at the middle finger joint typically opt for treatment.
What is the importance of early treatment?
Currently, there are no completed studies that prove that early treatment can slow disease progression. However, there is promising research on the effects of anti-tumor necrosis factor therapy. Tumor necrosis factor (TNF) plays a role in increased collagen formation.
Radiotherapy has also been proposed to slow disease progression, though there remains a concern for the potential long-term adverse effects of radiation exposure.
What are the treatment options?
Treatments for Dupuytren's disease include conservative management, collagen injection, and surgery. In fact, there are a number of nonsurgical treatment options to consider.
Mild disease
Observation is appropriate for individuals with painless, stable disease with no impairment in function. Physical therapy and occupational therapy can help maintain range of motion during early stages of the disease.
Those who have mild symptoms from nodules early on in the disease may benefit from modifying the tools that they are using — if applicable. Using gloves with padding across the palm or using pipe insulation around handles might be helpful.
Patients with persistent or progressive symptoms might benefit from glucocorticoid (cortisone) injections if tenderness is present. This can occur in nodules or if the protective layer around the tendon becomes inflamed (tenosynovitis).
For patients with flexion contracture, options include collagenase injection, percutaneous needle aponeurotomy, and open fasciectomy.
Collagenase injection
Collagenase comes from a bacterium called Clostridium histolyticum, which produces an enzyme that breaks down collagen. Collagenase is injected directly into a cord, and the affected digit is manipulated under local anesthesia 24 to 48 hours after the injection.
Night splints are recommended for 6 months after the procedure. The likelihood of full or nearly full correction is higher for patients with less severe contracture (less than 50°) or with early stage disease.
Research indicates collagenase injections have resulted in a 75% contracture reduction. Research shows mixed results regarding recurrence, including a 9% recurrence at 2 years and a 47% recurrence in 5 years.
Percutaneous needle aponeurotomy
Percutaneous needle aponeurotomy (aponeurosis is the palmar fascia, and aponeurotomy involves cutting the palmar aponeurosis) is a procedure where a small needle is inserted through the skin to cut the Dupuytren's cord at multiple points.
The finger is then extended to rupture the weakened cord. This is done in the office like the collagenase injection. A splint is also recommended to maintain correct finger position. There is substantial improvement immediately but up to 65% recurrence within 3 to 5 years.
Older research shows that when the procedure is combined with triamcinolone, patients experienced a significantly greater maintenance of correction of flexion deformity at 6 months compared to aponeurotomy alone.
This procedure is typically reserved for milder contractures.
External beam radiation therapy
External beam radiation therapy can prevent progression and provide symptomatic benefit in patients with mild to moderate flexion deformities.
While no controlled studies have been performed, in one small study, contractures regressed in over 50% of patients at 1 year and stabilized in 37% of patients.
In a long-term follow-up of an average of 13 years of early stage contractures, more than 70% of patients remained stable. Roughly 60% of those in more advanced stages progressed.
Surgical fasciectomy
Surgical fasciectomy is mostly performed for advanced stages of disease. Surgery should be considered only with functional impairment. This procedure can be partial or total.
Partial palmar fasciectomy is the removal of diseased tissue within a finger. This is indicated if there is a flexion deformity of 30° at the knuckle or 20° at the middle joint. The recurrence rate is about 20% to 40% at 5 years.
Total fasciectomy is infrequently performed because it requires resection of all palmar and digital fascia, including nondiseased tissue. This is indicated if cords have formed in the digits or recurrence after a partial surgical procedure. Recurrence risk is lowest for total fasciectomy at 10% to 20% over 5-plus years.
Postoperatively, patients are entered into hand therapy to help maintain range of motion. Therapy and splinting should occur for at least 3 months to prevent contractures.
Benefits are seen after 6 to 8 weeks postoperatively. The postoperative management is thought to account for the majority of the positive surgical outcomes.
What are the most common side effects of treatment?
Steroid injection side effects include:
skin atrophy at the injection site
pain
swelling
tendon rupture
Radiotherapy side effects include:
skin dryness/peeling
redness or irritation
stiffness
hyperpigmentation
There is an extremely low risk of cancer at the site of radiation.
Collagenase injection complications include:
swelling
skin tearing
tendon rupture
bruising
Percutaneous needle aponeurotomy side effects include:
mild local pain
swelling
skin tears
bruising
Surgical fasciectomy complications include:
pain
nerve injury
damage of vessels leading to significant tissue death
infection
swelling
scarring
postoperative flare (pain, swelling, redness, stiffness)
Can Dupuytren's contracture lead to other conditions, such as anxiety and depression?
Dupuytren's contracture can affect quality of life and emotional well-being. Patients with contractures that affect both hands or those with significant hand disability may experience depressive symptoms.
Recommended treatments
Cognitive behavioral therapy is the first-line treatment for depression and anxiety related to chronic disease. It helps to reframe thoughts around the illness and to develop coping strategies.
If depression or anxiety becomes significant enough to also impact daily living, there are medications that can also be recommended for treatment of these symptoms.
Does Dupuytren's contracture treatment address the pain?
Pain is not the most common symptom of Dupuytren's. Discomfort resulting from the stretching of the skin can be relieved by some of the treatment options.
Steroid injections to alleviate pain can be prescribed for patients who have tenosynovitis or painful nodules.

Chesapeake Bay health grade dips after hottest year on record and extreme rainfall patterns
ANNAPOLIS, Md. (AP) — The health of the Chesapeake Bay declined in an annual report card on the nation's largest estuary released Tuesday, with scientists noting the effect of extreme rainfall patterns during the hottest year on record. The University of Maryland Center for Environmental Science gave the bay a C grade in its report card. That compares to a C-plus grade the bay received last year, which was the highest grade it had received since 2002. 'There was a substantial upturn in the overall Bay Health score in 2024, and it came down a little this year,' said Heath Kelsey, director of UMCES Integration and Application Network. 'Over the long term, though, there is still an improving trend from the 1980s until now. We think extreme weather may have had some impact on the scores this year.' The report noted that last year was the hottest year on record, with extreme rainfall patterns. 'While parts of the watershed experienced drought, brief but intense downpours can cause water to flow over the ground rather than soak into it, increasing the fertilizer, dirt, and debris carried into waterways,' the report said. Bill Dennison, vice president for Science Application at UMCES, said the changing climate is definitely having an effect on the bay. 'One of the things that we saw in Maryland, in particular, was a prolonged summer drought — not so much spring, but a summer drought — punctuated by these extreme runoff events,' Dennison said. 'So what was happening was that the crops didn't have enough water, so they're not soaking up the nutrients.' As a result, when it did rain, there were excess nutrients, like nitrogen and phosphorus, that were flowing into the bay, Dennison said. 'Now sadly, this is kind of our future,' Dennison said at a news conference at the Annapolis Maritime Museum near the bay. 'This is the kind of weather patterns that are starting to become more common, which is drought punctuated by extreme events.' Warmer weather winters and higher temperatures mean less oxygen in the water for aquatic life, stressing fish and shellfish, Dennison added. 'So these are some of the things that we have to overcome and build more resilience into our system,' Dennison said. Despite the grade drop, the report cited long-term improvements in dissolved oxygen in the bay's waters. That's the amount of oxygen present in the water that is needed to support bay aquatic life. The report also noted long-term improvements in aquatic grasses, which provide habitat and food for various species, improve water quality and protect shorelines from erosion. Phosphorus and nitrogen levels also have improved in the long-term in another positive sign. While they are needed by the bay's organisms, excessive nitrogen and phosphorus degrade the bay's water quality. Excess nitrogen and phosphorus fuel algal blooms that can cloud the water and block sunlight from reaching underwater grasses. Water clarity and chlorophyll-a scores, however, have declining long-term trends, the report said. Chlorophyll-a in the bay is an indicator of phytoplankton abundance and water quality. Improving trends can be attributed to management and restoration efforts at the regional, state, and local levels, the report said. Regionally, wastewater treatment plants have been upgraded and programs have been put in place to reduce nutrient and sediment input. The health of the bay is a reflection of what's happening across its six-state watershed, which includes Delaware, Maryland, New York, Pennsylvania, Virginia and West Virginia along with the District of Columbia. UMCES, which is marking its 100th anniversary, also provides a grade for the overall watershed health in its report card. It gave the watershed a grade of C-plus. The watershed health grade includes ecological, societal and economic indicators. The most concerning societal indicator was heat vulnerability, the report said, noting communities may be under heat stress due to hotter air temperatures, less tree canopy cover, and more paved surfaces.

Skill Checkup: Woman With Persistent Anemia and Fatigue
A 72-year-old woman presents with persistent anemia and fatigue. Her height is 5 ft 2 in (1.57 m) and weight is 131 lb (59.42 kg; body mass index of 24). She was diagnosed with low- to intermediate-risk myelodysplastic syndrome (MDS) with ring sideroblasts 2 years ago when she presented with unexplained macrocytic anemia. Bone marrow biopsy at the time showed blasts were 5%-7%, and her specimen tested positive for SF3B1 mutation and negative for del(5q) . Her erythropoietin levels were < 400 and she received erythropoiesis-stimulating agent (ESA) therapy, requiring ≥ 2 red blood cell (RBC) units over 8 weeks. However, despite ESA therapy, the patient presents with symptomatic anemia; her hemoglobin is 10.1 g/dL. There are no blasts in the blood; 16% of erythroid precursors with ring sideroblasts are identified. Because this patient's anemia is not responding to treatment, the likely diagnosis is MDS with ESA-refractory anemia. ESAs are a potential therapy for the treatment of patients with MDS. However, most patients with MDS either do not respond to ESAs or eventually will develop resistance to these agents. Progression to acute myeloid leukemia (AML) in myelodysplastic syndrome is defined by the presence of ≥ 20% blasts in the peripheral blood or bone marrow (World Health Organization criteria). In this case, the patient has no blasts in the blood and had 5%-7% blasts at diagnosis, which is consistent with MDS but not AML. Copper deficiency can cause a sideroblastic-like anemia, but it is typically associated with neurologic symptoms (eg, ataxia, paresthesias), leukopenia, and a history of risk factors such as zinc overuse, malabsorption, or gastric surgery. This patient has a known diagnosis of MDS with ring sideroblasts and a pathogenic SF3B1 mutation, strongly supporting a clonal myeloid neoplasm rather than a nutritional deficiency. Although symptomatic anemia is a major morbidity of MDS, the anemia described in the present case, refractory anemia with ring sideroblasts (MDS-RS), is a subtype often associated with SF3B1 mutations, which lead to defective RNA splicing and secondary mitochondrial iron accumulation. This results in the formation of ring sideroblasts. SF3B1 is the most frequently mutated splicing factor gene in MDS-RS, and it is associated with better outcomes and longer survival. In this case, the presence of this mutation confirms a diagnosis of MDS over secondary causes of ring sideroblasts. Anemia in MDS might or might not be symptomatic at presentation and varies in degree, from mild to severe. Clinical symptoms of MDS, including fatigue as described by this patient, arise because of low peripheral blood counts, usually from anemia, but also can occur from thrombocytopenia or neutropenia. Features predictive of ESA response include a lower baseline serum erythropoietin (EPO) level (< 500 IU/mL), a low transfusion burden (< 2 units a month), a fixed-dose regimen, shorter time from diagnosis to starting treatment, and diagnosis of refractory anemia or MDS-RS. Although the patient in the present case is in fact diagnosed with refractory anemia or MDS-RS, response rates to ESA therapy are variable in patients with lower-risk MDS, ranging from 30%-60%. In this patient population, close monitoring of hemoglobin level is recommended to avoid increases to > 12 g/dL (as it is associated with a risk for systemic hypertension and thrombosis). In addition, the immunomodulatory agent lenalidomide can reduce transfusion requirements in patients with lower-risk MDS and a normal karyotype. In MDS, anemia is usually anisocytic, with a normal or a hypochromic microcytic population coexisting with the macrocytes. It is also generally macrocytic (mean cell volume, > 100 fL) with RBCs that are oval-shaped (macro-ovalocytes). Punctate basophilia is observed in RBCs. Symptomatic anemia in MDS frequently presents as a hypoproductive macrocytic anemia, often associated with suboptimal elevation of serum EPO levels. The National Comprehensive Cancer Network (NCCN) guidelines advise that during MDS workup, cytogenetics, bone marrow aspiration with iron stain, biopsy, serum EPO, and other coexisting causes should be ruled out. For MDS to be classified as MDS-RS, as in the present case, anemia should be present but with low blasts in the blood; for bone marrow, either ≥ 15% of erythroid precursors with ring sideroblasts must be identified, or if SF3B1 mutation is present, ≥ 5% ring sideroblasts. The same guidelines also make recommendations for additional testing of symptomatic anemia with MDS. These include flow cytometry to evaluate for large granular lymphocyte and paroxysmal nocturnal hemoglobinuria clone. Human leukocyte antigen typing offers clinical value if the patient is a hematopoietic cell transplant candidate. Because the patient in the present case is considered lower risk, she probably is not at this juncture. Recombinant fusion protein, such as luspatercept, is the most appropriate option for this patient, given its approval for the treatment of anemia in patients with lower-risk MDS-RS who have not responded to treatment with ESAs. In patients with lower-risk MDS and symptomatic anemia, treatment is usually guided by cytogenetic findings, serum EPO levels, and the presence of ring sideroblasts or SF3B1 mutations. For patients with del(5q) , lenalidomide remains the preferred treatment regardless of EPO level. For those with SF3B1 mutations or ring sideroblasts ≥ 15% (or ≥ 5% with a mutation), luspatercept is preferred, with imetelstat recommended if EPO is > 500 mU/mL and the patient is ineligible for ESAs. In patients without these features, ESAs plus granulocyte colony-stimulating factor or imetelstat may be considered on the basis of EPO levels, with follow-up based on response. Escalation to agents like ivosidenib or enasidenib is recommended only in the presence of IDH mutations. Neither hypomethylating agents or allogeneic transplant are included in this lower-risk anemia-focused treatment pathway. Further, intensive induction chemotherapy is not typically utilized in this setting.

Astronomy show accidentally reveals unseen structure in our solar system
An accidental discovery might change how we think about one of the most mysterious structures in our solar system. The Oort Cloud, a large expanse of icy bodies revolving around the sun at a distance 1,000 times greater than the orbit of Neptune, is widely thought to be spherical — although it has never been directly observed. But during the preproduction of a show titled 'Encounters in the Milky Way,' which debuted Monday at the Hayden Planetarium in New York City, a projection on the planetarium's dome revealed something strange within the Oort Cloud: a spiral. The curators were testing out a scene in September that includes a detailed view of Earth's celestial neighborhood — from the sun to the solar system's outer edges — and were surprised when they saw the structure, which looked coincidentally similar to a spiral galaxy such as our own. 'We hit play on the scene, and immediately we saw it. It was just there,' recalled Jackie Faherty, an astrophysicist at the American Museum of Natural History and the curator of the show. 'I was confused and thought that was super weird. I didn't know if it was an artifact, I didn't know if it was real.' To investigate, Faherty got in touch with David Nesvorny, an institute scientist with the Southwest Research Institute in Boulder, Colorado, and the Oort Cloud expert who had provided scientific data for the scene. 'We didn't create it — David did,' Faherty said. 'This is David's simulation, and it's grounded in physics. It has a totally good physical explanation for why it should be there.' At first, Nesvorny suspected artifacts — abnormalities or distortions in the data visualization — but once he looked at his data, he confirmed the presence of the spiral and eventually published a scientific paper about the discovery in April in The Astrophysical Journal. 'Weird way to discover things,' he said. 'I should know my data better, after years of working with it.' The existence of the Oort Cloud was first proposed in 1950 by Dutch astronomer Jan Oort, who imagined it as a shell of icy bodies swirling around the sun from up to 1.5 light-years away. The cloud is the most distant region in our solar system, stretching as much as halfway to the next star, according to NASA. It's composed of leftovers from the making of our solar system, which were scattered in every direction by the planets after they formed. That means many of the icy bodies in the Oort Cloud don't share the same orbital plane as the solar system itself but travel at various inclinations, which is why the Oort Cloud is pictured as a sphere. If one of those icy bodies gets flung inward toward the sun, the heat starts vaporizing some of the material in the body, creating a tail — and what we call a comet. 'Every now and again, some of these icy bodies come into the inner solar system, and we can see the orbit that they're on,' Faherty said. 'And they're on these really crazy, long orbits. It can take them millions of years to go around the sun. And when they come in, they help us understand how far away they may have come from.' The problem with trying to imagine what the Oort Cloud looks like is that scientists have never seen it, even though we are technically surrounded by it. That's because the bodies that make it up are small — fewer than 60 miles (97 kilometers) in diameter — and even though they potentially number in the trillions, they are far away, making observations with telescopes difficult. The spiral was hiding in Nesvorny's data because he had never thought of visualizing it three-dimensionally. 'I never looked at it in Cartesian coordinates — I didn't have a good reason to do so,' he said. 'But once you do that, it's obvious. It's there.' To confirm the findings, Nesvorny used one of the most powerful computers in the world, NASA's Pleiades Supercomputer, to run simulations that took weeks to complete. 'I thought, maybe just this particular simulation (I gave the planetarium) is showing it, and all the other simulations with other stellar encounters, other parameters, will not show it, in which case it wouldn't be so interesting,' he said. 'But all the simulations, all the models I have, show the spiral.' The reason it's there, he said, is that objects in the Oort Cloud are far away enough from the sun's gravity that they also start being affected by the galactic tide — the gravitational field of our galaxy, exerted by the stars and the dark matter in it. This field is acting on the small bodies and comets in the Oort Cloud by twisting their orbital planes to create a spiral. The spiral, Nesvorny added, is in the inner part of the Oort Cloud, the closest to us, and he still believes that the outer portion is spherical or shell-shaped. The problem of observing the Oort Cloud remains, even though the Vera C. Rubin Observatory, a powerful telescope that recently came online in Chile, could offer a hand by discovering and observing individual icy bodies in the cloud. However, according to Nesvorny, the telescope will likely discover dozens of these bodies — not the hundreds that would be required to produce a meaningful visualization of the spiral. The spiral theory helps to illuminate the dynamics of our solar system, according to Faherty. 'If you're going to come up with a theory of how solar systems evolve, you should take into account the kind of shapes you might have in their structure,' she said. 'Maybe comets helped deliver water to Earth. Maybe the building blocks of life could be out there in the Oort Cloud, so if you want to talk about the potential building blocks of life that surround our solar system, you need to understand its shape.' It's a 'dream,' she added, to be able to present science so recent in a show aimed at the general public. 'I truly believe that the planetarium, the dome itself, is a research tool,' Faherty said. 'I like to say that this is science that hasn't had time to reach your textbook yet.' The spiral finding is a wonderful example of just how much we can learn through visualizing the universe in new ways, said Malena Rice, an assistant professor of astronomy at Yale University who did not participate in the study. 'This result reshapes our mental image of our home solar system, while also providing a new sense for what extrasolar systems' Oort clouds may look like,' Rice added. 'It unites our models of the solar system with what we know about the broader galaxy, placing it into context as a dynamic system. We are not static, and we are not isolated — our solar system is shaped by its broader ecosystem, and the Oort spiral exemplifies that.' While the paper is interesting, it is almost entirely theoretical, as it is based on numerical simulations of the interactions between the sun's gravity and the gravitational pull of the rest of the Milky Way galaxy's motion, said Edward Gomez, an astrophysicist and honorary lecturer at Cardiff University in the UK. He also was not involved with the study. 'Long period comets enter the inner solar system at a range of angles, which the authors try to model using their spiral arm idea,' Gomez said in an email. 'What they are proposing could be true, but it could also be modelled by other shapes of the Oort cloud or physical processes. How to test this is their major issue, because only a handful of potential Oort cloud objects are known about.' Confirming the findings will be a challenge, noted Simon Portegies Zwart, a professor of numerical star dynamics at Leiden University in the Netherlands who was not part of the team behind the research. 'It is interesting that they found the spiral, (but) it seems unlikely that we are going to witness (it) in the foreseeable future,' he said. With luck, he added, the Vera Rubin observatory will detect a few hundred inner Oort Cloud objects, but the spiral would only be visible if many more are found: 'It therefore seems unlikely to be a clearly detectable structure.'
