RT Journal A1 Crompton JG, Oyetunji TA, Pollack KM, et al T1 Association between helmets and facial injury after a motorcycle collision: An analysis of more than 40 000 patients from the national trauma data bank JF Archives of Surgery JO Archives of Surgery YR 2012 FD July 1 VO 147 IS 7 SP 674 OP 676 DO 10.1001/archsurg.2012.894 UL http://dx.doi.org/10.1001/archsurg.2012.894 AB Motorcycle collisions are increasing at a precipitous rate, and reliable and valid data regarding all aspects of helmet safety are needed to better inform ongoing debates on mandatory helmet laws. The objective of this study was to determine the effect of motorcycle helmets on the likelihood of a facial injury after motorcycle collisions, using data from the National Trauma Data Bank, version 7.0, on 46 362 patients from January 1, 2002, through December 31, 2006. Multiple logistic regression was used to analyze the independent association between helmets and facial injury with adjustment for potential confounders. Helmeted motorcyclists were less likely to suffer facial injuries after a motorcycle collision, with a lower adjusted odds ratio of facial injury (0.40; 95% CI, 0.37-0.43) and a lower prevalence of specific types of facial injury compared with their nonhelmeted counterparts.
