4 Corner Wrist Fusion

I wrecked my sport bike about 3 years ago. I had to have carpal tunnel surgery as well as a 4 corner fusion. My Scaphoid was removed. All happened on my left wrist. I used to be an avid lifter while in the military. I’ve gone a couple times since the accident and I’m afraid of RE-injurying my wrist. Has anyone gone through this type of injury and what have you done to get back into the gym? What did you have to do for alternative exercises?
