We often take for granted how much our hands can accomplish, from opening pickle jars to reaching into a pocket to grab some change. For people with the hand deformity Dupuytren's contracture (pronounced du-pwe-TRANZ), these seemingly simple tasks pose much bigger challenges.
What Is Dupuytren's Contracture?
Dupuytren's contracture is a condition that causes thick, tough tissue to form under the skin of the palm. The thickened, shortened tissue eventually forces some of the fingers to curl inward toward the palm, creating a hand deformity.
Legend has it that the Vikings originally spread Dupuytren's through parts of Europe and Scandinavia hundreds of years ago. This is why Dupuytren's contracture is often referred to as "Viking's disease." The incidence of Dupuytren's contracture is still highest in countries like Norway, Scotland, Iceland, and Australia, where there are large numbers of people of northern European descent.
Swiss doctor Felix Platter was the first to describe Dupuytren's contracture in the 1600s. Many years later, the condition was named for French surgeon Baron Guillaume Dupuytren, who gave a now-famous lecture on retracted fingers in 1831.
What Causes Dupuytren's Contracture?
More than three centuries have passed since Dupuytren's was first discovered, yet doctors still don't know exactly what causes the condition. They believe that at least some cases are related to genes and inherited through families.
Dupuytren's Contracture Symptoms
The first sign of Dupuytren's contracture is a hard knot or lumps of connective tissue that form under the skin of the palm. These lumps might feel tender to the touch, but they usually aren't painful. Over a period of many years, the knots become bands of thick tissues. The bands extend up the fingers -- usually the ring and pinky fingers, although other fingers can be affected.
As the bands tighten, they pull the involved fingers in toward the palm. Eventually it becomes impossible to fully straighten the fingers. The shortening of the fingers caused by the thick tissue is called contracture.
Both hands can be affected by Dupuytren's contracture, but one hand is usually more severe than the other.
The hand deformity makes it harder to grasp large objects. You may have more trouble doing things like opening jars or doors or combing your hair. You should still be able to pick up small objects, because the thumb and index finger usually aren't involved.
The palm is the most common site of Dupuytren's contracture. However, Dupuytren's can be associated with conditions that cause contractures in other areas of the body, including the:
- Knuckle pads (Garrod knuckle pads)
- Soles of the feet (Ledderhose disease)
- Penis (Peyronie's disease)
Tests for Dupuytren's Contracture
Your doctor should be able to tell that you have Dupuytren's contracture just by looking at your bent fingers and feeling the tissue on your palm. The doctor might also check the strength and range of motion in your affected hand.
One test that can help diagnose the condition and determine whether you need surgery is the "table top" test. During this test, place your hand, palm side down, on a table. If the hand does not lie flat, the symptoms of Dupuytren's contracture are probably significant enough that you need to have surgery.
