Slicing open my hand renders my left thumb useless, is this true?

Well, A few years ago, when I was about 9-10, I sliced open the webbing between my left point finger and my left thumb. Only until now I have noticed I could never bend my left thumb, I can't make a good fist because its always pointing straight.





Was it slicing my Hand open that rendered my thumb unbendable, or was it from birth, because I don't remember doing anything else that could harm my thumb.Slicing open my hand renders my left thumb useless, is this true?
Look at your right hand and wiggle the thumb in various ways. Notice where the muscles and tendons have to be located and how they pull. If the slicing went though one of those areas then that motion won't work any more.Slicing open my hand renders my left thumb useless, is this true?

ask a doctor. they can even tell you on the phone for free i betcha.
Yes slicing open your hand injuried your nerve or tendon and since this wasn't treated you can't move your hand
