I broke my hand a few years ago. Had to have 3 pins inserted as well. I never had a cast and was told to get moving it around immediately. I was good to go in 3-4 weeks with me exercising it constantly.
I separated the bones between my pinky and index finger in my hand.
Granted, I wasn’t catching balls from Allen, but was lifting weights and doing things normally again within 3-4 weeks.
