UPDATE: Governor Dayton Recovering from Spinal Surgery

Dayton spokeswoman Kathleen Tinucci  says the Mayo Clinic surgeon who performed the procedure Thursday reports it went as planned, without any complications. She says the governor was out of surgery and awake by mid-afternoon.

Dayton hopes the operation will relieve a constriction in his lower back, known as stenosis, which Mayo says is generally caused by normal wear-and-tear on the spine due to aging. The procedure involves fusing vertebrae that shift out of alignment.

Dayton turns 66 in a few weeks.

He is scheduled to be released by Monday and will then return to St. Paul. He plans to work from the Governor's Residence during his recuperation period.
