Helmet use is up on ski slopes but no decline in brain injuries

Beaver Creek, Colo. • The fact that Michael Schumacher was wearing a helmet when he sustained a life-threatening head injury while skiing in France on Sunday probably did not come as a surprise to experts who have charted their increasing presence on slopes and halfpipes in recent years. That the helmet did not prevent Schumacher’s injury probably did not surprise them, either.

Schumacher, the most successful Formula One driver in history, suffered a traumatic brain injury when he fell and hit his head on a rock while navigating an off-piste, or ungroomed, area at a resort in Méribel, France. Although he was wearing a helmet, his injury has left him fighting for his life in a hospital in Grenoble, France.



Schumacher’s injury also focused attention on an unsettling trend. Despite the fact that more skiers and snowboarders in the United States than ever are wearing helmets — 70 percent of all participants, nearly triple the number from 2003 — there has been no reduction in the number of snow-sports-related fatalities or brain injuries in the U.S., according to the National Ski Areas Association.

Experts ascribe that seemingly implausible correlation to the inability of helmets to prevent serious head injuries like Schumacher’s and to the fact that more skiers and snowboarders are engaging in risky behaviors: skiing faster, jumping higher and riding out of bounds.

"The equipment we have now allows us to do things we really couldn’t do before, and people’s pushing limits has sort of surpassed people’s ability to control themselves," Chris Davenport, a professional big-mountain skier, said.

Dave Byrd, the ski association’s director of risk management, attributed the surge in helmet use to grass-roots efforts by resorts, helmet manufacturers and medical professionals to encourage their use. He also cited growing public awareness about brain injuries, a result of persistent news media attention on the issue in sports, particularly in the NFL; and several high-profile skiing fatalities, like the ones that killed actress Natasha Richardson and congressman Sonny Bono.

New Jersey is the only state that mandates helmet use, requiring it for children 17 and under.

The increase in helmet use has had positive results. Experts say helmets have reduced the incidence of less serious head injuries, like scalp lacerations, by 30-50 percent, and Schumacher’s doctors say he would not have survived his fall had he not worn a helmet.

But growing evidence indicates helmets do not prevent some of the more serious injuries, like the tearing of delicate brain tissue, said Jasper Shealy, a professor emeritus at Rochester Institute of Technology.

Shealy, who has been studying snow-sports-related injuries at Sugarbush resort in Vermont for more than 30 years, said that could be because those injuries typically involve a rotational component that today’s helmets cannot affect. He said his research had not seen any decline in what he called PSHI’s, for potentially serious head injury, a classification that includes a diagnosed concussion, skull fracture, closed head injury, traumatic brain injury or death by head injury.

In fact, some studies indicate that the number of snow-sports-related head injuries has increased.

A 2012 Western Michigan University School of Medicine study on head injuries among skiers and snowboarders in the U.S. found that the number of injuries increased 60 percent in a six-year period, from 9,308 in 2004 to 14,947 in 2010, even as helmet use increased by an almost identical percentage during the same period. A March 2013 study by the University of Washington concluded that the number of snow-sports-related head injuries among adolescents increased 250 percent from 1996 to 2010.

Experts agree that the roots of the trend are complicated and could be related to increased awareness about brain injuries and reporting them. But they also agreed on one element underpinning the trend: an increase in risk-taking behaviors that they said the snow-sports industry had embraced.

In recent years, many resorts have built bigger features in their terrain parks and improved access to more extreme terrain. At the same time, advances in equipment have made it easier to ski faster, perform tricks and venture out of bounds.

"There’s a push toward faster, higher, pushing the limits being the norm, not the exception," said Nina Winans, a sports medicine physician at Tahoe Forest MultiSpecialty Clinics in Truckee, Calif. "So, all of those factors — terrain parks, jumping cliffs and opening terrain that maybe wasn’t open in the past — play into some of these statistics with injuries."

The population most susceptible to this culture is the one that is dying, statistics show. Seventy percent of snow-sports fatalities involve men in their late teenage years to late thirties, according to the ski association, the same population that most often engages in high-risk behaviors like driving fast.

Head injuries remain the leading cause of fatalities in skiing and snowboarding, Shealy said, with about 30 such deaths in the U.S. each year.

"The helmet does a very good job at protecting against skull lacerations and skull fractures, but it doesn’t seem to have much effect on concussions or TBI’s," Shealy said, referring to traumatic brain injuries. "Our guess is that this is due to the fact that those injuries are occurring at such a high magnitude of energy that they overwhelm what a helmet can do for you."
