Another famous guitarist with hand injuries was Django Reinhardt, jazz player in 30s/40s (I think). He was this gypsy dude whose hand got burned when his caravan caught fire. He lost his 2 middle fingers I think. Nonetheless, some years later the famous classical guitarist Andres Segovia heard him play and asked where he could get some of his music from. He was told that he couldn't, it was improvised... Respect!!
Under-rated, Shaun Baxter. I listened to Satriani for years before I heard him and had acclimatised to being demoralised by widdley playing but this guy REALLY scared the crap out of me. What's'more nobody else sounds like him. It's really jazzy yet heavy with tons of freaky expressive bending, sweeps, taps and pinches and the oddest timings conceivable. Some people would say its soul-less but that's not always the case, he can play beautiful music when he's not playing stunt guitar.
