Did you know that only a few people in the world have an extra wrinkle on the bottom of their little finger? Congratulations if you are one of them!
Only a few people in the world have an extra crease on their little finger.
My left little finger has an extra joint crease but no extra joint by u/SHoo98 in slightly interesting
Take a look at your hands now; if you’re in the majority, you’ll notice two creases on your little finger.
If you have a third, you are one of a very small and rare number of people who have an extra transverse interphalangeal.
That sounds difficult, but it just means you have an extra crease on your little finger. As you may know, the phalanges are the bones that make up the fingers and toes, each finger has three and the thumb has only two.
If you don’t want to call it an extra transverse interphalangeal muscle because it sounds too ‘Marvel’ for you, how about a supernumerary digital flexion fold? Both options are available to you.
Anyway, if you look at your hands right now, the extra crease is most likely just above where a ring would go on your little finger, and while it happens most of the time on that finger, you can see it on other fingers as well. . .

There is no specific explanation for this function.
There isn’t much research on the subject, why should there be? – but what is there tends to focus on the smallest finger. So, let’s talk about the rarity of this feature.
In 1978, Japanese scientists collected data on 551 people and determined that only six of 1,102 tiny fingers (one on each hand, obviously) had this extra wrinkle.
Fascinatingly, or not, you decide, all the men had them on one little finger, while the women had them on both hands. Another study, which included just 307 people, found that the abnormality is more common in men than women.
Obviously, that’s a small study, so we shouldn’t read too much. There is no specific explanation as to why this feature might appear, nor is there any information on whether it is tied to anything.
It will almost certainly be related to genetics, but there has been little scientific interest in it since, let’s face it, it doesn’t seem like a particularly relevant or intriguing topic in medical science.
However, it could be useful in forensics. Because it is so rare, it can be beneficial to recognize the handprint of someone who was involved in an incident. Therefore, it could be used in that field as a scar, a tattoo or any other identifying feature.
In any case, if you simply looked at your hand and noticed an extra crease on your finger, you now have something to brag about that sets you apart from the vast majority of people. Isn’t that lovely?
