Britain's former prime minister Margaret Thatcher had successful surgery to insert a pin into her arm Friday, her son said, after she broke it in a fall last week.
The 83-year-old is expected to remain in hospital until at least Wednesday, Mark Thatcher said outside the Chelsea and Westminster Hospital in London.
AdvertisementThe increasingly frail Thatcher was taken to hospital last Friday after having fallen at her central London home.
Her son said he was "relieved" and "delighted" that the general anaesthetic operation went well. He said described the operation as "a complete success".
The fracture to the former premier's upper arm had been "moving about a little bit" and had struggled to repair due to its position under the deltoid muscle, he said.
"Every time she moved her shoulder the fracture site was moving, which prevented proper union.
"She will probably be going back to the ward this evening... we are relieved it has gone so well.
"I shall be coming back to see my mother when she comes out of recovery."
He added: "There is no prospect of her leaving at the weekend... She wants to go home as quickly as possible but that's in the hands of the people in charge of her aftercare."
Baroness Thatcher's daughter Carol is recovering from eye surgery but has also visited her mother.
The former prime minister's spokesman said the operation was "a routine surgical procedure to insert a pin into the bone of her upper arm, in order to assist the healing process.
Thatcher, dubbed "the Iron Lady" for her uncompromising leadership style, is Britain's only female prime minister. She headed a Conservative government between 1979 and 1990 and overhauled the British economy during the 1980s.
Thatcher has suffered a series of strokes in recent years and now suffers from dementia. She generally avoids public speaking on doctors' advice.
She spent a night in hospital in March last year after feeling unwell during dinner with friends.
But she has been spotted out and about recently -- last week, she celebrated the 30th anniversary of her first election victory at a London club.
