PORTLAND — A 14-year-old surfer had his left arm reattached by surgeons following a collision with a dory boat near Pacific City.

Dr. Steven Madey, a surgeon at Portland’s Legacy Emanuel Hospital, said Tuesday it may take months to know whether Cole Ortega of Bend will regain use of the arm, which had been severed just above the elbow.

But he said the arm wouldn’t have been reattached at all if not for the efforts of numerous people after Sunday’s incident. The boyfriend of Ortega’s sister applied a tourniquet and another surfer recovered the severed limb that was quickly put on ice. Madey also credited an emergency room physician who happened to be on the beach and the teams responsible for rushing the boy to Portland.
