What about six fingers?

Six fingers, also known as polydactyly, is a common orthopedic congenital disease, often related to heredity, with polydactyly of the fingers and toes visible at birth, which can occur individually or bilaterally symmetrically. Surgery is necessary to remove the extra fingers and restore the normal shape of the fingers and the appearance of the hand. If your child has six fingers, you must go to the hospital for surgery at an early stage in order to get a better result.
