A DOCTOR has walked 10 kilometres in the snow after getting stuck in traffic gridlock in order to perform life-saving brain surgery.

Dr Zenko Hrynkiw was at the Brookwood Medical Centre in Alabama on Tuesday morning when he was called by the Trinity Medical Centre saying he was needed for emergency brain surgery.

Dr Hrynkiw jumped in his car but only got a few blocks due to the traffic issues created by a snowstorm that hit the southern US states.

"The cell service was bad so we were fading in and out," said Steve Davis, charge nurse in the neuro intensive care unit at Trinity. "At one point, I heard him say, 'I'm walking.'"

Mr Davis called police to see if they could find Dr Hrynkiw and bring him in, but with no luck.

After a few hours passed, he had completed his epic trek.

"He finally called me and said, 'Where's the patient? What's the status?'" Mr Davis said. "He spoke to the family and went off to surgery."

Dr Hrynkiw is Trinity's only brain surgeon.

"Without the surgery, the patient would have most likely died," Mr Davis said. "But he is doing well."

"This just speaks volumes to the dedication of the man," Mr Davis said. "When I saw him, all I could say is 'You are a good man.'"

Mr Davis said Dr Hrynkiw frequently walks for exercise.

No doubt he fulfilled his workout for the week.
