German driver Sophia Floersch broke her spine in a high-speed crash during a Formula 3 race in Macau but said she was "well" at the hospital.
The 17-year-old driver lost control of his Van Amersfoort car at a speed of just under 280 km / h on Sunday.
Her car hit teammate Sho Tsuboi before being catapulted by air and fencing.
Floersch was aware and transported to the hospital, later tweeting that he would undergo surgery on Monday.
"I just wanted everyone to know I'm fine, but I'm going to have surgery tomorrow morning," she said.
Officials said she suffered a fractured spine.
Ferrari's Chinese driver, Guan Yu Zhou, was behind Florsch at the time of the crash and blamed the yellow warning lights flashing on the straight.
"First of all, it was such a scary time," Zhou said.
"Sophia was very close to Jehan, so when Jehan braked early she did not have time to react.
"She hit Jehan's right rear, and that led her straight to Lisbon, and she flew into the other car. I just hope she's okay.
Her father had told DPA before that she was able to move her whole body.
Four other people were taken to the hospital, including Japanese driver Tsuboi, two photographers and a track marshal. All were aware of and treated for several back, head and face injuries, the reports said.
Floersch, who will turn 18 on December 1, is competing in his first season in the junior F3 series. She was in 15th place when the accident happened on the fourth round of the street circuit.
The race continued after a break of about an hour and was defeated by the British pilot Daniel Ticktum, 19 years.
The German Mick Schumacher, son of the great Michael Schumacher of Formula 1, was one of several motorsport stars to send messages of support to the teen star.
