Have You Noticed That Your Pinky Finger Has An Extra Crease? There Are Relatively Few People Around the Globe Who Possess It.

Only a minuscule fraction of people have a pinky that has this additional crease.

It's possible you're not aware of it, but your pinky can have a trait that's quite unusual and little understood. An additional interphalangeal transverse is what it is called, and all it is is a third crease on the little finger.

It's also known as a supernumerary digital flexion crease, and it's normally located right above the spot where a ring would rest on the little finger, just below the crease that's made by the primary bend in the finger. Even though the little amount of study that has been done on extra finger creases has focused on the fact that they are found on the little finger, additional grooves have been observed on other fingers as well.

Consider the fact that your finger has this tiny minor flaw, which is a real rarity if it is present.

A phenomenon that emerged in Japan in 1978, when researchers collected 551 individuals and measured the number of wrinkles on their pinkies. Only six of the 1,102 young fingers that were examined were found to have an additional transverse wrinkle. It is interesting to note that the additional creases were only seen on one of the male participants' little fingers, but on both of the little fingers of the female participants they were observed.

It was hypothesized in research that it could be somewhat more prevalent in boys than in girls, but it was based on a single sample of 307 individuals in India, so the results may not be generalizable.

The manner in which connective tissue is connected to the underlying bone is related to the formation of wrinkles in the skin. In most cases, they may be found in the joints, since this is the location where connective tissue has to be attached to the underlying tissues. On the other hand, those whose fingers have an extra interphalangeal transverse do not have an extra joint in those fingers.

Nobody really knows why some individuals have additional wrinkles in their fingers, but some people definitely have them. Several research have been conducted in an effort to establish a connection between it and various health concerns; however, no one ailment has ever been shown to have a clear and direct connection to it.

If you've only recently realized that you have an additional pinky crease, there is no need for you to get into a state of panic.

There is a possibility that it is influenced in some way by genetics, but there is no evidence that researchers have ever looked at this. After all, this is not precisely a subject that needs an immediate answer in the field of biological research.

The investigation of additional interphalangeal transverse may, on the other hand, have some applications in the real world.

A research that was conducted in 2015 focused on the potential applications of the characteristic in the area of forensics. For example, if the handprint of the perpetrator of the crime has an additional crease, then it should, in theory, be rather simple to exclude some of the potential candidates. In a similar vein, the added crease might serve as a distinguishing characteristic that aids in the identification of a victim or a missing individual, much in the same way as a noticeable scar, mole, or tattoo would.
