OBJECTIVE: Current protocols for spine immobilization of the injured skier/snowboarder have not been scientifically validated. Observing changes in spine alignment during common rescue scenarios will help strengthen recommendations for rescue guidelines.
METHODS: Twenty-eight healthy volunteers (18 men, 10 women) age 47±17 (range 20-73) (mean ±SD with range) underwent a mock rescue in which candidate patrollers completing an Outdoor Emergency Care course performed spine immobilization and back boarding in 3 scenarios: 1) Ski helmet on, no c-collar; 2) helmet on, with c-collar; and 3) helmet removed, with c-collar. After each scenario, a lateral radiograph was taken of the cervical spine to observe for changes in alignment.
RESULTS: Compared with the control group (helmet on, no collar), we observed 9 degrees of increased overall (occiput-C7) cervical extension in the helmet on, with collar group (P < .001), and 17 degrees in the helmet off, with collar group (P < .001). There was increased extension at the occiput-C2 intersegment in the helmet on, with collar group (9 degrees, P < .001) and at both the occiput-C2 (9 degrees, P < .001) and C2-C7 (8 degrees, P < .001) intersegments in the helmet off, with collar group.
CONCLUSION: Ski helmet removal and c-collar application each leads to increased extension of the cervical spine. In the absence of other clinical factors, our recommendation is that helmets should be left in place and c-collars not routinely applied during ski patrol rescue.
