Iv done similar damage to my right wrist, but the pain isn't too bad, can still do pushups, but it less painful to do it on my knuckes, weirdly enough.

I don't find that weird at all, I've not had a wrist injury and I find that trying to do pushups with my hands flat on the floor is very uncomfortable and "tweaks" my wrists in a way that almost feels like I'm on the verge of spraining them or something. I think it's because in that position the forearms are pointing down towards the ground while the hands are almost bent back towards them and not taking a great deal of the stress... the stress of supporting one's weight is borne by the wrist joint, because that's where the "line" from shoulder to ground really ends.
Doing pushups from the knuckles with the hands in fists tends to keep the hands and forearms aligned in more of a straight line. The stress can travel down that line through the wrist joint and meet the ground at the knuckles and so the hand itself is bearing most of it.
I don't know if I'm explaining this right, I don't know the terms for it. But it's the same principle involved when throwing a punch - you make a fist and do not bend your wrist this way or that, when the arm is extended to deliver the force of the blow, the back of the hand making the fist should form a straight line with the forearm so that the power can travel straight down that line through the arm to the point of contact with the target. You wouldn't bend your fist back at the wrist and try to "push" the force of the blow into the target at the wrist joint, number one it would be a lousy punch and number two you'd be risking a wrist injury.
