Pediatric and adolescent injury in motocross.

Motocross is a competitive outdoor extreme sport in which motorcyclists race across vast courses of jumps, berms and long straightaways of unpredictable terrain. While the sport has gained notoriety in adult popular culture through contests like the X Games, motocross is also increasingly popular among youth in the Unites States and beyond. In the setting of contemporary discussions on traumatic brain injury, this poses an obvious challenge to those advising children and parents on the risks of motocross to the developing brain and spine. The available literature demonstrates that even when practiced with appropriate protective equipment, motocross poses an increased risk for acquiring major trauma to the brain, spine and limbs for which the long-term consequences have been poorly studied. Riders and parents should be counseled about the risks of these injuries prior to participation and in accordance with state laws. Furthermore, formal return-to-play guidelines following concussions should be developed.
