In a recent letter published to fans, U2 frontman Bono explains the severity of his injuries after suffering a bike injury in Central Park only a few months ago. The note explains that he hasn’t “been able to move around physically” for the past few weeks, and that he now has a titanium elbow. As for the injury itself, Bono says that he “blanked out on impact and have no memory of how I ended up in New York Presbyterian with my humerus bone sticking through my leather jacket.” He continues, saying, “Very punk rock as injuries go.”

The recovery process of the injuries has clearly taken a toll on the singer.

“Recovery has been more difficult than I thought. As I write this, it is not clear that I will ever play guitar again. The band have reminded me that neither they nor western civilization are depending on this.

“I personally would very much miss fingering the frets of my green Irish falcon or my (red) Gretsch. Just for the pleasure, aside from writing tunes.

“But then does the Edge, or Jimmy Page, or any guitarist you know have a titanium elbow, as I do now? I’m all elbows, I am.”

Bono continues, mostly rambling, saying that this will be his only communication for the first part of 2015, and that he will be focusing on recovering to get in shape for U2’s upcoming tour schedule. You can read the full letter here.
