My son has crooked pinky fingers on both sides. It is very obvious now. But I never noticed it when he was a baby..not until he was about two. One day I was cutting his nails and thought oh my he broke his pinky...until I saw the other one!
The orthopedist told me that he always had it but it became more obvious over time because as the fingers grow the growth plates, which are placed in the wrong place so not directly under the joint but partly to the side, push the finger the wrong way--sort of crooked instead of up. Turns out this is usually inherited and the gene for this is an autosomal dominant. So when it is in the family (either parent) all the kids get it to some degree. It is usually mild. Turns out my pinky fingers are slightly bent but it is so subtle I never noticed it. My son's brother is the same way and so mild you wouldn't even notice. I had no clue but all my siblings and my dad have it too! My sister's pinky fingers are more dramatic like my son's are so she was aware but I certainly wasn't.
Do either you or his dad have slightly bent pinky fingers? If so do a search for clinodactyly.
It is just one pinky, the other is fine. He can almost straighten it just by trying (when I ask him to), but not quite. I can force it straight if I try. My pinkies look fine, but I will check my husband's when he gets home. Which way do your son's bend sideways or down?
