Copenhagen - Danish Crown Prince Frederik has undergone surgery after sustaining a leg injury while sledging with his children, the palace said Wednesday.

The procedure was conducted Tuesday at Copenhagen University Hospital. The 41-year-old heir to the Danish throne was likely to leave hospital on Thursday.

The prince sustained the shinebone fracture while sledging during a recent ski holiday in Switzerland.

His children, Prince Christian and Princess Isabella, were not hurt in the crash.

The prince will likely wear a cast for the coming six weeks, but according to the palace was expected to carry out his official schedule. (dpa)
