David Cifaldi of Billings fell while hiking at high elevation and unintentionally impaled himself on one of his own trekking poles. “By the time I rolled over, I kind of knew something wasn’t right,” David Cifaldi, the impaled hiker, told KTVQ. “Through my skin I could feel the trekking pole.” They had to backtrack 10 miles to the trailhead with Cifaldi impaled. The surgeon attached a drain to the pole so as the pole was pulled out, the drain was pulled in.
