Former Speedway GP contender Leigh Adams has undergone surgery following his devastating crash while preparing for the Finke Desert Race on Tuesday, with doctors confirming he has suffered extensive spinal cord damage.

Adams, 40, has been confirmed that have fractured several vertebrae, as well as suffering extensive spinal cord damage, punctured lungs, broken ribs, a broken scapula and a small fracture in his neck.

The 10-time Australian Speedway Champion was flown to Adelaide on Tuesday night from Alice Springs and yesterday underwent a marathon six-hour operation on his back to stabilise and strengthen his badly injured spine.

Surgeons are understood to be very happy with the outcome of the operation.

Leigh’s wife, Kylie, says he is doing better than expected given the magnitude of his injuries.

“He has no feeling in his legs at present except a little bit in one thigh,” Kylie explained. “But, that situation could certainly change and improve in the weeks and months ahead. He faces a long hard road to recovery.

“He’s currently in intensive care but could be moved out today into the special spinal unit. He’s actually very stable and probably a bit too well to be in intensive care. He’s very alert and talking.

“Leigh has no head injuries at all which is wonderful news. He’s just very sleepy due to the pain medication being administered,” Kylie concluded.

The international speedway star, who only retired from active competition in January this year, following a stellar 20 year career at the top level, had aspired to compete in the gruelling Finke Desert race for some time and was excited to be finally fulfilling a long held ambition.

It’s uncertain if Adams will require further surgery to his injuries in the coming days.
