Push Ups with a bad wrist...how to

I think push ups are cool and I am in awe of people who can do them. I struggle to do them because of my injured wrist. I had a surgery previously on it, plus I suspect something like RSI. I can do 5 to 10 on a fresh wrist, and about 3, after doing any kind of exercise that involves the use of the wrist.  AND I have to do an adjustment. I do push ups on my knuckles/fingers, too painful to do on a flat palm.
The push ups I was doing on the pic, were done at the end of my weight training. It was chest day, so heavy dumbells 10-12kg flys and press ups. So obviously, with every 3rd push up I was falling flat on my face :)))
