2010 was his back surgery. Don’t think there was a specific incident mentioned for him having to have that surgery but the bike accident that ended his guitar playing days was definitely late 2014.
But in the fall of 2014, right before they were scheduled to do a bunch of SOI promo shows, Bono had a significant injury after a bicycle accident in Central Park. All scheduled appearances were cancelled, and Bono didn't appear in public for several months, until the lead up to the SOI Tour in May 2015. The nerve damage apparently caused him to lose motion/dexterity in some of his left fingers, thus he can no longer play guitar.
