Researchers capture breakthrough data on cervical spine injuries
Date:7/26/2011

DURHAM, N.H. A high school football player's broken neck from which he's recovered has yielded breakthrough biomechanical data on cervical spine injuries that could ultimately affect safety and equipment standards for athletes. University of New Hampshire associate professor of kinesiology Erik Swartz collaborated on the study, which appears in a letter in the prestigious New England Journal of Medicine.

Swartz and lead author Steven Broglio of the University of Michigan captured this groundbreaking spinal fracture data while studying concussions. Broglio had fitted the helmets of football players at a high school in the Midwest with padded sensors as part of the Head Impact Telemetry System (HITS), which measures the location and magnitude of impacts to the helmet. During a head-down tackle, an 18-year-old cornerback in the study suffered both a concussion and a fracture of his cervical spine, or neck. (He has since fully recovered.)

"This is really novel," says Swartz, explaining that all previous research on cervical spine injuries have been done on cadavers, animals, or via mathematical modeling. "You can't create a cervical spine fracture in a healthy human, but here you have an actual event where we captured data during an actual cervical spine injury," he says.

Swartz notes that this research will bring real-world information to the study of axial load impact to the head and its effects on the spine. "We now have data that we know caused a serious spine injury in a healthy, 18-year-old strong-bodied athlete," he says.

Swartz, who teaches athletic training, was tapped by Broglio for his expertise in cervical spine injuries in athletes. Swartz helped analyze the acceleration data from the in-helmet sensors in collaboration with sideline video footage of the tackle to describe the effects of the impact to the player.

The authors see far-reaching implications for this work in the quest for greater saf
