When my wrist was giving me some pain here are some variations I did, it wasnt as serious as what youve mentioned however:
EZ curl bar standing curls and preachers
Cable push downs for triceps
You might want to experiment with different width grips on the barbell also, for any types of free weight presses. Dumbells will probabally be the worst for your wrist. It may take some experimentation to see what feels best. Hope that helps!!
