Keeping his cool in a sticky situation, an otherwise healthy, and seriously lucky, 40-year-old man drove himself to the hospital with a tree branch piercing out of the side of his neck after taking a nasty fall from his mountain bike during an off-road excursion.

“With a branch in his neck, he jumped back on the bicycle, rode the bicycle to his car, and then drove the car to the hospital,” which was about 20 miles from the accident, Lev Deriy, MD, of the University of New Mexico Health Sciences Center, in Albuquerque…

A stick lodged that far inside a person’s neck could have easily caused vascular, airway, nerve, and cervical spine injuries, the authors wrote, but this patient miraculously came out with nothing more than a small flesh wound. And kudos to the patient for not yanking the stick out on his own…

At the hospital, the surgeons removed the stick, explored for vascular and airway injuries, irrigated the wound and stitched it up. The patient’s postop was uneventful, and he “will definitely mountain bike again,” Deriy added.

And why not? After this, he should be used to staying calm when the stakes are high.
