Riyadh: Saudi Arabia`s royal palace says the kingdom`s aging ruler has had a second successful back operation in New York City.
The palace says the 86-year-old King Abdullah will start physical therapy following Friday`s surgery to stabilise a number of vertebrae.
Abdullah flew to New York on November 22 for medical treatment for what the palace said was a slipped disk and a blood clot pressing on nerves in his back.
His first surgery at the Presbyterian Hospital was to extract the clot and correct the disk.
Before he left for the United States, Abdullah temporarily handed control of the kingdom to Crown Prince Sultan, his 85-year-old half brother.
