Robert Kubica has completed a seven hour operation under Italian hand surgery specialist Prof Igor Rossello, but it will be some time before his true condition becomes clear.

“We have to wait at least a week to see if his hand survives,” Rossello told Italian media, apparently adding that it could take a year for the Pole to be able to use his right arm again.

Rossello, a specialist from the nearly San Paulo Hospital in Savona, was joined by Renault’s own doctor, Riccardo Ceccarelli.

Kubica underwent bone reconstruction before the doctors attended to tissue damage.
