Supreme Court justice Ruth Bader Ginsburg is back at home after being released from the hospital. She had been admitted for treatment and observation on Thursday morning after fracturing three ribs in a fall at her office in Washington on Wednesday, triggering widespread concern about the 85-year-old judge’s wellbeing.

The supreme court issued a statement on Friday morning saying Ginsburg had been allowed out of hospital. The supreme court spokeswoman, Kathy Arberg, said she is “doing well”, but is already back at work, although working from home.

The court had previously said the justice fell in her office at the court building on Capitol Hill on Wednesday evening and went to George Washington University Hospital in Washington the following morning after experiencing discomfort overnight. It was then confirmed that she had broken her ribs.

Ginsburg broke two ribs in a fall in 2012. She had two prior bouts with cancer and had a stent implanted to open a blocked artery in 2014. The liberal-leaning judge has previously said she would stay on the bench for as long as she felt fully fit and able to give the job her all. Her outspoken nature, in contrast to her diminutive stature, has earned her the popular nickname Notorious RBG, a play on the late rapper Biggie Smalls, known as Notorious BIG.
