Angela Merkel's spokesman Steffen Seibert told reporters the chancellor suffered what she first thought was just a bruise to her left rear pelvic area while cross-country skiing but doctors later determined it was an "incomplete'' bone fracture that will require her to rest for three weeks.
"The doctors' orders are to lie down,'' Seibert said, adding that she had canceled a Wednesday visit to Warsaw, Poland. Luxembourg Prime Minister Xavier Bettel has also called off his trip to Berlin which had been set for Thursday.
Angela Merkel would continue to preside over Cabinet and government meetings, using a walking aid to get around, he said.
Last week Angela Merkel sent wishes for a speedy recovery to German Formula One legend Michael Schumacher, who suffered a serious head injury while downhill skiing in France.
Seibert noted that Merkel, 59, had been engaged in the more placid pursuit of cross-country skiing and the fall had occurred "at low speeds.'' He was unable to say if another person was involved.
The accident happened around Christmas during Angela Merkel's annual ski trip to the Engadin region in southeast Switzerland.
