For safety reasons, I think the most important thing is to work on your flexibility and getting your elbows really high.
I also had an old wrist injury (stress fracture from 2 years ago) that left my right wrist considerably less flexible than my left. Last week, I was doing heavy cleans, ran out of juice, and wasn't able to get under it fast enough. Bent my wrist really badly, and now it's most likely sprained (same injury, potentially). But part of that was because the flexibility in that one was bad, so be really careful and just work on getting your elbows up super fast.
