George H.W. Bush released from hospital

Former U.S. President George H.W. Bush was released Sunday from a Maine hospital where he had received four days of treatment after breaking a bone in his neck in a fall at his summer home, his spokesman said.

Bush, 91, fell on Wednesday in his family's vacation home in coastal Kennebunkport and was taken to Maine Medical Center in Portland.

Spokesman Jim McGrath on Twitter described the former president as "very grateful" for his care.

In a Thursday press conference, his physician said that Bush did not sustain any spinal damage from the fall, though it left him with a cracked C2 vertebrae.

Bush served as vice president during Ronald Reagan's two White House terms before being elected president in 1988.

Bush is the father of former President George W. Bush and former Florida Governor Jeb Bush, who is seeking the 2016 Republican presidential nomination.

Bush, who has a form of Parkinson's disease that has him using a motorized scooter or wheelchair for mobility, has suffered a few other recent health setbacks. He was hospitalized in Houston in December for about a week for treatment of shortness of breath.

He spent Christmas 2012 in intensive care at the same Houston hospital while being treated for a bronchitis-related cough and other issues. He was discharged in January 2013 after a nearly two-month stay. During the winter, Bush and his wife, Barbara Bush, live in Houston.
