Biomechanical Engineer Discusses Injuries Suffered by Skier at Terrain Park

This case involves an injury suffered by a patron at a ski resort terrain park. On the date of the incident in question, the plaintiff – who was a talented downhill skier – had spent the majority of the day skiing various trails at the resort. Towards the end of the day, the man and his friends decided to spend some time on the terrain park. The park had recently been fitted with a large air bag, which was intended to provide soft landings following jumps from a large ramp. On the plaintiff’s first attempt to use the device, he performed a backflip and landed on the airbag. During the landing the man severely injured his lower back, causing permanent paralysis.

Question(s) For Expert Witness

1. Please briefly describe your experience working with injury biomechanics as it relates to skiing and/or snowboarding.

2. Do you have any level of participation in the winter sports industry setting any types of rules or standards for safety / injury prevention?

3. Can you speak specifically to the kinematics and biomechanics of front flips and back flips? Is one any more dangerous than the other?

Expert Witness Response E-115138

inline imageI have a PhD Biomedical Engineering studying the injury biomechanics of catastrophic neck injuries in head-first impacts, and I am an expert-level snowboarder with prior experience riding, coaching, and competing in terrain parks and halfpipes. My PhD thesis dealt exactly with this type of head-first impact and I am very comfortable and knowledgeable with the literature surrounding catastrophic neck injuries from head-first impacts. I have been a snowboarder for about 30 years. In the 1990's I was a sponsored rider and appeared in several magazines and movies. I suffered a (snowboard) career-ending injury in 1995 when I ruptured the extensor mechanism in my right knee. This was my foray into injury biomechanics and marked the start of my university education. While I have a deep understanding of the biomechanics of snowboarding I have not yet worked on any cases involving snowboarding injuries as a forensic biomechanical engineer up until this point. I can specifically speak to the kinematics and biomechanics of front flips and back flips. Both front flips and back flips can be dangerous however front flips tend to be less dangerous because the inverted part of the aerial occurs earlier and generally it is easier to keep rotating once started. With backflips, without proper technique, it is easier to end up performing only half the rotation and then landing head-first.
