I am 20 years male recently broke my pinky finger at a 70 degree angle from the middle joint up to my knucle. I done so playing basketball and I'm in a cast for 8 weeks. My question is when my cast is off can I give basketball 100 percent or will I want to take it easy due to a possible re-break or what I just have no ideal... I've never had a broken bone

You probably have to take it easy. Rest would be good. Chelax for about 2 weeks.
