Thoroughbred racehorse Centralinteligence underwent successful surgery after sustaining a hairline condylar fracture during the Breeders’ Cup Dirt Mile at Santa Anita Park, in Arcadia, Calif., and has an excellent chance to return to racing, trainer Ron Ellis said Nov. 7.

The condyle is the bulbous bottom or distal end of the cannon bone that fits into the fetlock joint.

The 5-year-old son of Smarty Jones returned to Ellis’ barn Nov. 6 after Wayne McIlwraith, BVSc, PhD, FRCVS, Dipl. ACVS, Dipl. ECVS, operated on him over the weekend, the trainer said. McIlwraith mended bone in the right front leg and inserted a couple stabilizing pins.

"He came out of surgery really well," Ellis said of Centralinteligence. "(McIlwraith) said the bone came back together very well. They do come back from this sort of injury. He gave him a 70% to 80% chance of returning to racing
