The surgery that occurred last Wednesday in the Oasis Center of San Diego was the hopeful solution to fix an injury that has plagued Hayden since it began following crashes at Indianapolis Motor Speedway and Motorland Aragon back in 2012.Some positive news arrived Friday when the Drive M7 Aspar team reported its rider Hayden is recovering well. Dr. James Chao, the physician in charge of the surgery, said the procedure was a success and the 2006 MotoGP Champion’s recovery is on track.But in order for 100-percent fitness and to regain full movement of his throttle wrist, Hayden must sit out the next rounds at Indianapolis Motor Speedway and Brno in the Czech Republic. The Drive M7 Aspar team reports that the 2009 British Superbike Champion Leon Camier (UK) will substitute for Hayden at those two rounds.Speaking of the recover, Nicky Hayden says “Although undergoing surgery is not usually a positive thing -not least because you lose a lot of time- I’m happy with how the operation went last week. Sometimes it is difficult, but we know that injuries are part of our sport and we must learn to manage them. Everyone knows that my wrist has been causing me problems, especially at recent races.“I underwent an operation in June, which helped me to complete the first half of the season, but the truth is I’ve been riding with a lot of discomfort, and have been unable to perform at my best. So, together with the team, we decided to make an important decision and undergo a larger operation to treat an injury that comes from three years ago -when I broke my scaphoid and did not heal well.“According to Dr. Chao the operation was a success and I am very happy, and focusing on my recovery. My right wrist still needs to be immobilised for another week. Then I will begin rehabilitation therapy, and I’ll slowly recover mobility. I want to thank the team, sponsors and fans for all the support they are giving me at this time.“In the first examination, a week after surgery, I received an injection of platelet-rich plasma to help heal bones. According to the doctor my recovery is on course, which is very positive. It takes patience, but if I have made the decision to have surgery it is to get back to my best. I made the decision thinking about being healthy for the end of the season and already thinking about next year.”The team reports that a fitness plan has been devised for Hayden to keep in shape during his layoff, so that when he returns to action he will be at 100 percent.
