Rossi was thrown from his Fiat Yamaha M1 bike as he went through Turn 13, with the temperature of his tyres having been cited as a likely factor in his highside crash. Doctor Roberto Buzzi of the CTO performed the surgery, assisted by Doctor Claudio Costa of the Clinica Mobile, in a two-and-a-half hour procedure that went according to plan.
"We received Valentino Rossi at the Careggi Hospital, where we made detailed checks in order to rule out any other injuries, and the results were satisfactory,” explained Doctor Buzzi in a post-operation statement. “We therefore decided to proceed with the surgery for the exposed fracture of the right leg. We performed a spinal block (epidural) and cleaned and washed the fracture, which was then aligned and stabilised with a pin. The surgery had good results; the alignment was good and the bone is now stable. The wound remains open, as is usual in these cases, and it will be stitched in the next few days with another short surgery. We are confident that Valentino will be able to leave the hospital in a week to ten days, able to put weight on the leg with the aid of crutches.”
Doctor Buzzi continued: "It is difficult to say how long the post surgery rehabilitation will take, we need to evaluate the progress of the patient and also what the X-rays will show. But I think that we can reasonably think of six weeks of partial weight-bearing with crutches, after which Valentino needs to be re-evaluated, according to his feedback and further x-rays."
