Jorge Lorenzo has undergone successful surgery on the collarbone injury that ruled him out of the MotoGP Sachsenring weekend.
The Spaniard flew to Barcelona on Friday night in order to have an operation on his damaged shoulder. He bent the titanium plate inserted onto his Assen collarbone break when he was flicked off his Yamaha exiting Turn 10 early on in second practice.
Doctors at the Hospital General de Catalunya said they had been forced to change the plate, and also inserted bone substance taken from Lorenzo's pelvis in a bid to hasten his recovery. The Spaniard's participation in next weekend's Mazda Raceway Laguna Seca race remains uncertain.
"As a result of the trauma suffered in the crash yesterday the original fracture suffered a little movement that required a new surgery, to close the space and reduce the fracture by the osteosynthesis method and with a new plate," surgeon Dr. Joaquin Rodriguez reported.
"The new plate needed 10 screws plus 1 inter fragmentary screw. We then needed to take out some bone substance from the pelvis that was mixed with dried bone. We placed this implant into the collarbone to stimulate the creation of the callus and help speed up the consolidation of the bone. The operation lasted two hours."
