Bush senior at Mayo for hip replacement

ROCHESTER (AP) -- Former President Bush had his left hip replaced Tuesday morning at the Mayo Clinic, and the clinic reported that things went well.

The surgery was completed at 7:40 a.m., the clinic said in a statement. The clinic did not say how long the surgery lasted. Bush, 76, was resting comfortably in his hospital room.

He was expected to be hospitalized for five days.

Former first lady Barbara Bush also had successful hip replacement surgery at the Mayo Clinic in December 1997.

Both Bush and his wife also have a thyroid disorder, called Graves' disease.
