The writer's wife Chaz took to her Twitter.com page on Thursday (06Dec12) to announce the news, joking her husband's ""tricky disco dance moves"" are to blame for his latest hospital trip.
She adds, ""He is doing well, asking for computer, will probably tweet.""
Chaz Ebert tells the Associated Press that ""doctors are making assessments"" about when her husband can leave the hospital - and the movie critic took to his own Twitter page later in the day to assure fans he would not need an operation.
In a post, he wrote, ""Yes, fracture. But no surgery needed.""
The 70 year old has previously battled cancer of the thyroid and the salivary gland, which left him unable to speak. He has had a full-time, live-in nurse since 2010.
