Pitching angle from elbow to wrist

#1

Is a 8 to 13 year old at greater risk to have to have Tommy John surgery throwing with an arm angle from elbow to wrist greater than 90 degrees? Please advise

#2

I throw with my arm up idk if that means elbow to wrist im 13 and i havent had any troubles.

#3

Keep the elbow below the shoulder plane and you’re okay.

I’m not sure I understand correctly, but the elbow to wrist is ALWAYS greater than 90 degrees when you throw a baseball. Do you have a pic or vid?

#5

Are we talking about how much the elbow is bent? At what point in the delivery?
