LOS ANGELES — U2 lead singer Bono has been released from Ludwig Maximilians-University (LMU) Hospital in Munich, where he underwent emergency surgery on Friday for a back injury.
"Bono suffered severe compression of the sciatic nerve," Dr. Muller Wohlfahrt said in a statement on the band's official Web site. "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. I recommended Bono have emergency spine surgery with Professor Tonn at Munich's LMU University Hospital on Friday."
"He was already in severe pain with partial paralysis in the lower leg," added Tonn. "The ligament surrounding the disc had an 8mm tear and during surgery we discovered fragments of the disc had traveled into the spinal canal. 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."
Bono, 50, will need at least eight weeks of rehab to recuperate.
"While the surgery has gone very well, the coming weeks are crucial for a return to full health," Wohlfahrt said. "In the next days, he will start a light rehabilitation program, with increasing intensity over the next eight weeks. In our experience, this is the minimum time."
On Tuesday, U2 canceled a planned appearance at next month's Glastonbury Festival.
"I'm heartbroken," said Bono, who personally called Glastonbury founder Michael Eavis to share the disappointing news. "We really wanted to be there to do something really special - we even wrote a song especially for the Festival."
U2 also postponed the upcoming leg of its 360° North American tour until 2011 in order to allow Bono sufficient time to recuperate.
"Our biggest and I believe best tour has been interrupted and we're all devastated," said the band's manager, Paul McGuinness. "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."
