Do you know there are some famous figures who have more than five fingers? Call it Hritik Roshan (bollywood actor), Antonio Alfonseca (ball thrower in Major League Baseball), Gemma Arterton (actress), Hound Dog Taylor (blues guitarist), and Gary Sobers (West Indian cricketer). Surely the extra fingers in his hand did not prevent them from continuing to work in his life. But why do these people have more fingers than normal people?
The phenomenon of having more than five fingers and toes is referred to as polidaktili.
What is polyactivity?
Polidaktili is a congenital physical disorder in humans that is characterized by having extra fingers or toes so that it looks more than five. Polydactyly comes from the Greek "polys", which means "lots", and "daktylos, which means" finger. "
Polidaktili is usually only on one side of the hand. Additional fingers are usually located on the side of the thumb (radial), pinkie (ulnar), or in the middle (central). Post-axial polydactyly is most commonly found in black populations. Whereas in Asia, the most common fingers found are in the thumb (pre-axial polydactyly). The advantages of these fingers are perfectly shaped like normal fingers, but there are also abnormal growths; smaller and "live" with other fingers.
Polidaktili is diagnosed after a thorough medical history and a careful physical examination. X-rays are often used to diagnose and identify each bone of the fingers and hands.
What causes someone to have more than five fingers?
During the development of the embryo in the womb, the hand which is originally shaped like a duck's paddle will split into five fingers separated from one another. Polidaktili occurs when there is an error in this process, so that an additional finger is formed from one finger which is split again into two.
Many cases of polydactylliy occur for no apparent reason, while some other cases occur due to genetic defects. Polydactyl can also occur due to offspring. Polydactyl is the most common birth defect and is experienced in about 1 in every 1,000 births.
Here are some of the possible causes of known polycytili:
1. Genetic and chromosomal abnormalities
Polidaktili can be genetically inherited (autosomal dominant). If one spouse has a polyacetyl, it is very likely that the child will experience the same thing. Genetic abnormalities in the father or mother are also likely to affect the polydactyles experienced by the child.
2. Factors of birth defects
This physical disorder can be caused by various factors that cause children to be born with physical disabilities, for example, exposed to exposure to nuclear radiation, gamma rays, and x-ray. X-rays that are too frequent and repetitive at pregnancies less than 12 weeks can provide a disability in the form of birth defects in the fetus.
Many substances and drugs used to treat certain diseases are also at high risk of causing birth defects in children if consumed during pregnancy. Alcohol is one of them. Pregnant women who consume liquor, especially in the first trimester can cause physical disability in their fetus, also increase the risk of abnormalities known as fetal alcoholic syndrome.
Exposure to severe viruses during pregnancy, such as TORCH, Toxoplasma, rubella, cytomegalovirus, syphilis, and herpes can also increase your child's risk of having more than five fingers. TORCH infection can cause various birth defects, miscarriages, until the death of the fetus in the womb.
Can this disorder be treated?
Polydactyl treatment can only be done surgically, and the technique also varies. The simplest is surgery to remove the entire extra finger, or more complex, surgery involving the bones, ligaments, and tendons in the hand tissue.
