What was first described by the band as a "spill" with surgery required is actually numerous severe fractures, one of which was a fracture on the left side of his face "involving the orbit of his eye," according to a statement to the Los Angeles Times from orthopedic trauma surgeon Dr. Dean Lorich.
In addition to his facial injury, Bono's left shoulder blade was fractured into three pieces, the statement said.
The 54-year-old suffered a compound fracture to the elbow where "the bone of the humerus was driven through his skin, and the bone was in six different pieces."
Bono's elbow was repaired with three metal plates and 18 screws, according to the release. The singer also suffered a broken finger on his left hand.
Bono is expected to make a full recovery, the doctor's statement said, but will require "intensive and progressive" physical therapy.
Hospital officials said it was unclear how long Bono would be hospitalized.
Multiple calls to Interscope Records and Bono’s manager for comment were not returned.
The band has yet to release a new statement addressing future plans.
