Michael Schumacher is set to have stem cell surgery by a world renowned doctor in a bid to regenerate his nervous system.
The Formula One icon suffered his devastating skiing accident six-and-a-half years ago and his physical condition has largely been closely guarded by those around him.
Schumacher suffered a severe brain injury in 2013 and the latest operation will take place in the coming days, according to Italian media reports.
The operation will be performed by French professor and cardiologist Dr Philippe Menasche.
He is a world renowned medical pioneer and is understood to have operated on Schumacher before, last September.
He pioneered the technique of grafting stem cells onto a damaged heart and results have shown it is a safe procedure.
The 51-year-old former Formula One supremo is having damaged cells replaced with healthy ones that have been harvested from bone marrow or blood.
He was in a coma for six months after the head injury suffered whilst skiing off-piste in the popular resort of Meribel in the Alps.
Italian publication Contro Copertina report that the seven-time world champion is suffering from being bed-ridden for so long with his muscles wasting away and his bones becoming weak.
The latest operation is part of an ongoing series of them and they are ‘part experimental’.
A spokeswoman for Schumacher declined to comment.
Schumacher fell and hit his head on December 29, 2013 while skiing off-piste with his son Mick. He suffered a traumatic brain injury, was air-lifted to hospital and placed in a medically induced coma.
After 254 days he returned home, where he has largely remained ever since.
Although specifics have been kept secret, Jean Todt, former manager of Ferrari, said last year that the driver was making ‘good progress’ and can watch F1 races on TV.
