Former US President George H.W. Bush suffered a neck fracture in a fall at his home in Maine late yesterday, though he was listed in stable condition and his hospital stay was expected to be brief, his spokesman said.
Bush, 91, who served as America's 41st president, was last hospitalized in Houston for a week in December 2014 after experiencing breathing difficulties.
Bush was taken to Maine Medical Center in Portland, where he is expected to be held overnight, a hospital spokesman told NBC News.
McGrath told CNN the former president was never disoriented and that his stay at the facility was not expected to be long.
Bush is the father of President George W. Bush and of former Florida Governor Jeb Bush, who is now seeking the Republican nomination for the 2016 presidential election.
The elder Bush, a Republican like his sons, served as vice president for eight years during Ronald Reagan's two terms in the White House before being elected president, defeating former Massachusetts Governor Michael Dukakis, the Democratic nominee, in 1988.
Bush took office in 1989 and served four years in the White House, during which he organized the US-led military coalition that defeated Iraqi forces after Saddam Husseininvaded Kuwait.
He lost his 1992 re-election bid to Democrat Bill Clinton.
Bush previously served as a congressman, a U.N. ambassador, a U.S. envoy to China and director of the Central Intelligence Agency before becoming Reagan's running mate in 1980.
A Navy pilot during World War Two, he celebrated his 90th birthday on June 12, 2014, by skydiving near Kennebunkport, Maine, with the Army's Golden Knight parachute team. He currently suffers from Parkinson's disease and cannot use his legs.
