Hannah Weyerhauser was 5 years old, playing on the zipline at her family’s house in New Hampshire, when she started complaining that her older cousins and siblings were going faster than she was. So her mother, Annie, gave Hannah an extra big push. But when Hannah sped to the end of the zipline, she stopped short, flew into the air, did a back flip, and landed on her neck.
“For a few minutes she was really pale and out of it,” said her mother, a Boston doctor (and a friend of mine). She called an ambulance, and paramedics put a collar on Hannah’s neck on the way to the local emergency department. Ultimately, the little girl was fine, although she probably had a minor concussion, her mother said. But Annie shudders as she thinks of what could have happened: “If she had fallen a little differently she could have broken her neck.”
Others are not so lucky. Increasingly, zipline disasters are making the news. A 12-year-old girl in North Carolina died after falling off a zipline at the YMCA’s Champ Cheerio in June. And last year, a 10-year-old boy died after a backyard zipline accident in Easton, Massachusetts, in which the tree holding the line fell on the child.
Indeed, injuries related to ziplines are rising as the lines proliferate, according to a new report: In 2012 alone, there were over 3,600 zipline-related injuries, or about 10 a day. The study, which researchers say is the first to characterize the epidemiology of zipline-related injuries using a nationally representative database, found that from 1997-2012, about 16,850 zipline-related injuries were treated in U.S. emergency departments.
The report on ziplines (first used over a century ago to transport supplies in the Indian Himalayas) found that most of the injuries resulted from falling off the zipline, and many involved young children. I asked one of the study authors, Tracy Mehan, manager of translational research with the Center for Injury Research and Policy at Nationwide Children’s Hospital in Ohio, a few questions about the report, published in the American Journal of Emergency Medicine.
Here, edited, is what she said.
Rachel Zimmerman: Are you surprised by this sharp increase in zipline injuries?
Tracy Mehan: The number of commercial ziplines grew from just 10 in 2001 to over 200 by 2012. When you include the number of amateur ziplines that can also be found in backyards and at places like outdoor education programs and camps, the number skyrockets to over 13,000. The increase in the number of injuries is likely due largely to the increase in number of ziplines and shows this is a growing trend.
What are the most common types of injuries?
The majority of zipline-related injuries were the result of either a fall (77 percent) or a collision (13 percent) with either a tree, a stationary support structure or another person. The most frequent type of injuries were broken bones (46 percent), bruises (15 percent), strains/sprains (15 percent) and concussions/closed head injuries (7 percent). Approximately one in 10 patients (12 percent) were admitted to the hospital for their injury. Continue reading
