Stoner undergoes wrist surgery

Ducati rider Casey Stoner underwent successful surgery on his wrist on Thursday in Italy and has already left hospital.

The Australian, who had been hindered by the injury since it reemerged during the latter part of the 2008 season, got two floating bodies removed from the area of the styloid process of the lower arm.

The 2007 world champion was treated for pseudoarthrosis on his left scaphoid before the removal of a staple, which had been inserted during an operation in 2003.

He also received a bone graft using the Herbert Bone Screw System, which is designed to promote early active motion.

Stoner will begin his rehabilitation over the next few days in Switzerland.
