Bono has been released from a Munich hospital after undergoing emergency back surgery late last week.
He'll begin a rehabilitation program to recuperate for at least eight weeks, Live Nation said in a statement.

"Bono suffered severe compression of the sciatic nerve. On review of his MRI scan, I realized there was a serious tear in the ligament and a herniated disc, and that conservative treatment would not suffice," said Dr. Muller Wohlfahrt. "I recommended Bono have emergency spine surgery with Professor Tonn at Munich's LMU University Hospital on Friday."
When Bono was admitted to the hospital Friday, "He was already in severe pain with partial paralysis in the lower leg. The ligament surrounding the disc had an 8mm tear and during surgery we discovered fragments of the disc had traveled into the spinal canal," said his surgeon, Professor Tonn.
"This surgery was the only course of treatment for full recovery and to avoid further paralysis. Bono is now much better, with complete recovery of his motor deficit. The prognosis is excellent, but to obtain a sustainable result, he must now enter a period of rehabilitation."
Dr. Muller Wohlfahrt said, "We are treating Bono as we would treat any of our athletes, and while the surgery has gone very well, the coming weeks are crucial for a return to full health. I
U2 manager Paul McGuinness, who was at the hospital in Munich said, "Our biggest and I believe best tour has been interrupted and we're all devastated. For a performer who lives to be on stage, this is more than a blow. He feels robbed of the chance to do what he does best and feels like he has badly let down the band and their audience. Which is of course nonsense. His concerns about more than a million ticket buyers whose plans have been turned upside down, we all share, but the most important thing right now is that Bono make a full recovery. We're working as fast as we can with Live Nation to reschedule these dates."
U2's 360° North American tour will be postponed until 2011.
