Dupuytren's contracture vs trigger finger: what is the difference?
- Jun 2

If one or more of your fingers has started to bend and you cannot straighten it properly, two conditions often come up: Dupuytren's contracture and trigger finger. Both affect the fingers and both can interfere with everyday life, but they are different conditions with different causes, different symptoms and different treatments. Understanding the distinction matters, because the right treatment depends entirely on getting the diagnosis correct.
This guide explains how the two conditions differ, what symptoms to look out for, and when it is worth seeing a specialist.
What is Dupuytren's contracture?
Dupuytren's contracture is a condition in which the tissue beneath the skin of the palm gradually thickens and tightens. Over time, this tissue forms thick cords that pull one or more fingers into a permanently bent position. The ring finger and little finger are most commonly affected, though any finger can be involved.
The condition develops slowly, usually over months or years. In the early stages there may be a firm lump or nodule in the palm, which is often the first sign. As the condition progresses, the cords become more prominent and the affected fingers begin to curl towards the palm. The bending is permanent: the finger cannot be straightened, even passively.
Dupuytren's (also known as Viking disease) is more common in men, particularly those of Northern European descent, and tends to run in families. It becomes more prevalent with age, most often appearing in people over 50. It is not usually painful, though the early nodules can be tender to the touch.
What is trigger finger?
Trigger finger, known medically as stenosing tenosynovitis, affects the tendons that control finger movement. The tendons that flex your fingers run through a series of protective tunnels called pulleys. In trigger finger, inflammation causes the tendon or the tunnel around it to thicken, which makes the tendon catch as it tries to slide through. This produces the characteristic triggering sensation: the finger clicks, locks or snaps as it moves.
Unlike Dupuytren's contracture, trigger finger often causes pain, particularly at the base of the finger or in the palm. In mild cases the finger clicks when bent and straightened. In more severe cases it becomes locked in a bent position and may need to be manually straightened with the other hand. In the most severe cases the finger locks completely and cannot be moved at all.
Trigger finger can affect any finger, including the thumb (where it is sometimes called trigger thumb). It tends to come on more quickly than Dupuytren's and is associated with repetitive gripping activities and conditions such as diabetes and rheumatoid arthritis.
Dupuytren's contracture vs trigger finger: key differences at a glance
A summary of the main differences between dupuytren's contracture vs trigger finger:
Cause
Dupuytren's: thickening of the palmar fascia (connective tissue in the palm). Trigger finger: inflammation of the tendon sheath causing the tendon to catch on a pulley.
Which fingers are affected
Dupuytren's most commonly affects the ring and little fingers. Trigger finger can affect any finger and is especially common in the ring finger and thumb.
Type of bending
Dupuytren's causes a gradual, permanent bending of the finger that cannot be reversed passively. Trigger finger causes locking, catching or clicking that may resolve when the finger is forced straight.
Pain
Dupuytren's is usually painless, though nodules may be tender early on. Trigger finger typically causes pain at the base of the finger or palm, especially when gripping.
Speed of onset
Dupuytren's develops slowly over months to years. Trigger finger tends to develop over weeks to months.
Who is affected
Dupuytren's is more common in older men of Northern European descent. Trigger finger can affect adults of any background and is more common in people with diabetes.
How are they diagnosed?
Both conditions are diagnosed clinically, meaning a surgeon or doctor can usually identify them through a physical examination without the need for scans or blood tests. Your surgeon will examine the shape of your hand at rest, assess how far you can bend and straighten each finger, check for cords or nodules in the palm, and ask about how your symptoms developed and how quickly.
In some cases, particularly when the diagnosis is uncertain or when both conditions may be present, an ultrasound scan can provide useful information about the tendons and surrounding tissue.
Can you have both conditions at the same time?
Yes, it is possible to have Dupuytren's contracture and trigger finger simultaneously. Both conditions are more common in people with diabetes, and some patients develop both independently. This can make diagnosis more complex, which is one reason why an assessment by a specialist hand surgeon is valuable. Treating one condition without identifying the other will not fully resolve the problem.
Treatment options
Treating Dupuytren's contracture
For mild Dupuytren's where the finger can still be straightened, monitoring may be all that is required initially. When the condition progresses to the point where function is affected, the main treatment is surgery. A fasciectomy involves removing the thickened cords and tissue from the palm to allow the fingers to straighten again. In selected cases, needle fasciotomy (dividing the cord using a needle) or collagenase injection may be considered.
Treating trigger finger
Trigger finger treatment depends on severity. Mild cases may respond to a splint or anti-inflammatory medication. A steroid injection into the tendon sheath is effective for many patients, particularly in the early stages. If the triggering persists or recurs, or if the finger has locked, surgical release of the tight pulley is the most reliable solution. This is a straightforward day-case procedure performed under local anaesthetic.
When to see a specialist
If your finger is bent and you cannot straighten it, or if it is catching and clicking when you move it, it is worth seeking an expert assessment. Both conditions are very treatable, and the sooner they are properly diagnosed, the more options are available to you.

FAQ
Can trigger finger turn into Dupuytren's contracture?
No. They are separate conditions with different underlying causes. Trigger finger involves the tendon and its sheath, while Dupuytren's involves the connective tissue beneath the skin of the palm. Having one does not cause the other, though both can occur in the same person at the same time.
Is it possible for a bent finger to straighten on its own?
A finger bent by Dupuytren's contracture will not straighten on its own; the condition is progressive. A finger locked by trigger finger may occasionally loosen, particularly with splinting or anti-inflammatory treatment, but in moderate to severe cases it requires active treatment to resolve.
Does Dupuytren's contracture affect the right and left hand equally?
Dupuytren's can affect one or both hands. When both hands are affected, the dominant hand tends to be more severely affected. The condition does not spread from one hand to the other but can develop independently in both.
How long does it take to recover from trigger finger surgery?
Most patients can use the hand for light activities within a few days of trigger finger release surgery. The finger usually returns to normal movement within four to six weeks, though full recovery can take up to three months depending on how long the finger was locked before surgery.
Is Dupuytren's contracture the same as a Dupuytren's nodule?
A Dupuytren's nodule is the earliest sign of Dupuytren's contracture. The nodule is a firm lump in the palm, often at the base of the ring or little finger. Not all nodules progress to full contracture, but they are part of the same condition and should be monitored by a specialist.
