One of the more unusual conditions affecting the hands and fingers is Dupuytren's contracture (also called Dupuytren's disease). Here, one or more fingers become curled, which can make it difficult to pick up or hold objects or perform everyday activities.
Legend says the condition originated with the Vikings of Northern Europe, although this is debated. It was later named after the 19th-century French surgeon Guillaume Dupuytren, who did the first successful operation on the condition. Fast-forward to the 21st century, and Dupuytren's contracture now affects about one in 20 Americans.
What is Dupuytren's contracture?
Fascia is a sheet of fibrous tissue beneath the skin of the fingers and the palm. Dupuytren's contracture is a thickening and shortening of this tissue.
This thickened area begins as a hard lump called a nodule. Over years to decades, it may progress to a thick band called a cord that causes one or more fingers to curl toward the palm and become stuck in a bent position. This can make it difficult to grasp objects, button clothes, use a computer, or perform other daily tasks.
The condition does not always get progressively worse. It may be stable for years or even improve in some people.
Which fingers are most likely to be affected?
The ring and pinky fingers are most often affected. But the condition can strike all fingers and the thumb.
"In about half of cases, the condition can affect both hands," says Dr. Phillip Blazar, an orthopedic surgeon and Division Chief of Hand and Upper Extremity at Harvard-affiliated Brigham and Women's Hospital. Fortunately, it rarely causes pain.
What causes Dupuytren's contracture?
Currently, the cause is unclear. Still, several factors can increase a person's risk, such as
People with diabetes and seizure disorders are also more likely to have Dupuytren's. The condition may appear and/or worsen after trauma to the hand.
How is Dupuytren's contracture treated?
Although there is no cure, treatments and occupational or physical therapy can help address symptoms and improve finger mobility. "Many people who have mild cases of Dupuytren's find it has little impact on their ability to use their hands," says Dr. Blazar.
However, moderate or severe cases can interfere with hand function. It's possible to restore normal finger motion with nonsurgical treatments, such as:
"Your hand surgeon will discuss both treatment options to determine which is best for your situation," says Dr. Blazar. "There are also some variations in the anatomy of the disease which may make one treatment or the other less favorable for a particular person or finger." Both of these treatments don't remove the cords, and the condition can return and require additional treatment.
What about surgical treatment?
If nonsurgical treatment does not relieve symptoms or you have a severe condition, surgery may be recommended. Surgical approaches include:
You wear a splint on the repaired hand during recovery. People should expect some pain, stiffness, and swelling afterward. The length of recovery varies for each individual, and also with how many fingers were operated on and which ones.
"Most people largely recover by three months, but some may not feel fully recovered for quite a bit longer," says Dr. Blazar. Hand therapists can also help with strength and flexibility exercises to speed recovery.
Most people's fingers move better after surgery. However, as with nonsurgical treatments, the contracture can come back, so some people may need additional surgery later on.

In parts of the United States and Canada, warming temperatures driven by climate change may be contributing to a rise in tick-borne illnesses. Ticks are now thriving in a wider geographic range, and appearing earlier and sticking around later in the shoulder seasons of spring and fall. That means we need to stay vigilant about protecting ourselves against ticks that cause Lyme disease and other illnesses — even during winter months in many warmer states and provinces.
Here's a timely reminder about why preventing Lyme disease is important, and a refresher on steps you can take to avoid tick bites.
What are the symptoms of Lyme disease?
Lyme disease is best known for its classic symptom, a bull's-eye red rash that appears after a bite from an infected tick (scroll down to see photos of classic and non-classic rashes). However, 20% to 30% of people do not develop a rash. And a rash can be easy to miss because ticks tend to bite in dark body folds such as the groin, armpit, behind the ears, or on the scalp. Some people have flulike symptoms such as a headache, fever, chills, fatigue, and aching joints. So if you notice a rash or have these symptoms, call your doctor for advice. At this stage, prompt antibiotic treatment can wipe out the bacterial infection.
When people don't receive treatment because they didn't see the rash or didn't have other early symptoms, the bacteria can spread to different parts of the body. Not only can the bacteria itself cause problems, but the body's immune system can over-respond to the infection. Either process, or sometimes both, may harm joints, the heart, and/or the nervous system. And some people treated for any stage of Lyme disease develop post-Lyme disease syndrome, which can cause a range of debilitating symptoms that include fatigue, brain fog, and depression.
How to avoid getting Lyme disease
Preventing tick bites is the best way to avoid Lyme disease and other tick-borne illnesses. Blacklegged ticks (also called deer ticks) may be infected with the bacteria that causes Lyme disease. If you live in one of the areas where the incidence of Lyme disease is high, these steps can help.
Know where ticks are likely lurking. Ticks usually crawl up from leaves or blades of grass on the ground to the legs. So be extra careful when walking through fields or meadows and on hikes where you may brush up against bushes, leaves, or trees. Try to walk on well-cleared paths.
Wear protective clothing. Long pants tucked into socks is the best way to keep ticks from crawling up under the pant leg. Lighter-colored clothing can make ticks easier to see.
Use repellents. You can buy clothing that's pretreated with the insecticide permethrin (which repels ticks). Or you can spray your own clothes and shoes; just be sure to follow the directions carefully. On all exposed skin, use a product that contains DEET, picaridin, oil of lemon eucalyptus (OLE), IR3535, para-menthane-diol (PMD), or 2-undecanone. This search tool from the EPA can help you find a product best suited for your needs. Pay attention to the concentration of active ingredients: for example, at least 20% but not more than 50% with DEET; between 5% to 20% with picaridin; and 10% to 30% with oil of lemon eucalyptus. Many products come in pump spray bottles or as sticks or wipes, which may make them easier to apply where needed.
Get a tick check. After spending time in tick-infested areas, ask a partner to check you for ticks in areas on your body that you can't see very well. The common bite areas are the back of the knee, the groin, under the arms, under the breasts in women, behind the ears, and at the back of the neck. The tick species that transmits Lyme disease is about the size of a sesame seed. Note that a tick has to be attached to your skin for 24 to 36 hours for it to transmit enough bacteria to give you the disease.

Need a little motivation and structure to ramp up your walking routine? Want to wake up your workouts but not quite ready for a mud run? Consider trying a couch-to-5K program.
Dr. Adam Tenforde, medical director of the Spaulding National Running Center at Harvard-affiliated Spaulding Rehabilitation Network and a sports medicine physician at Mass General Brigham Sports Medicine, shares tips on what to know and do before lacing up your sneakers.
What is a couch-to-5K program?
These free or low-cost coaching plans are designed to help would-be runners train for a 5-kilometer race, which is about 3.1 miles. The programs are available online, or as apps or podcasts. They typically feature timed walking and running intervals that gradually phase out the walking over a period of about nine weeks.
Why try a couch-to-5K program?
"One purpose of a couch-to-5K program is to give you time to acclimate and start to enjoy the benefits of running and the sense of accomplishment of completing a distance safely," says Dr. Tenforde. Running provides many cardiovascular benefits, such as lower blood pressure and a reduced cholesterol level, as well as an enhanced sense of well-being, he adds.
What's more, adding even short bursts of running or other vigorous physical activity to a workout — a practice known as high-intensity interval training or HIIT — appears to help improve mental health, according to a study that pooled findings from 58 randomized trials of HIIT.
Are you ready to tackle a couch-to-5K?
Even though the couch-to-5K programs sound as though they're geared for completely sedentary couch potatoes, that's not necessarily true, Dr. Tenforde cautions. These programs often assume you can walk continuously for 30 minutes, which doesn't apply to everyone.
For some people, an even easier, more gradual training regimen may be more appropriate. Also, keep in mind that you don't have to run to do a 5K. Many of these races also encourage walkers to participate as well. You'll still reap the other rewards from committing to a race, such as being more challenged and motivated — and possibly more connected to your community. Many charitable "fun runs" benefit local schools or needy families. Some are in memory of people affected by illness or tragedy. Visit Running in the USA to find 5K races near you.
What to do before you start
If you're planning to walk or run your first 5K, get your doctor's approval before you start training. That's especially important if you have heart disease or are at risk for it.
Comfortable walking or running shoes are a wise investment. Shoes that are too old or too tight in the toe box can cause or aggravate a bunion, a bony bump at the outer base of the big toe. Despite suggestions that people with flat feet or high arches need specific types of shoes, studies have found that neutral shoes (designed for average feet) work well for almost everyone. Walk or jog around the store when you try them on to make sure they feel good and fit properly.
You don't need to buy special clothes; regular sweat pants or comfortable shorts and a t-shirt will suffice. Women should consider getting a supportive sports bra, however.
Go slow and steady when training
Remember that you can always repeat a week. You're less likely to sustain an injury if you make slow, steady progress. Pay close attention to your body and don't push yourself too much, Dr. Tenforde advises. Former athletes who haven't run in years may think they can pick up where they left off, but that's not a smart move — they should also start low and go slow.
