Helmets are known to reduce the incidence of traumatic brain injury (TBI) after bicycle-related accidents. The aim of this study was to assess the association of helmets with severity of TBI and facial fractures after bicycle-related accidents.
The authors performed an analysis of the 2012 National Trauma Data Bank abstracted information of all patients with an intracranial hemorrhage after bicycle-related accidents. Regression analysis was also performed.
A total of 6,267 patients were included. About 25.1% (n = 1,573) of bicycle riders were helmeted. Overall, 52.4% (n = 3,284) of the patients had severe TBI, and the mortality rate was 2.8% (n = 176). Helmeted bicycle riders had 51% reduced odds of severe TBI (odds ratio [OR] .49, 95% confidence interval [CI] .43 to .55, P < .001) and 44% reduced odds of mortality (OR .56, 95% CI .34 to .78, P = .010). Helmet use also reduced the odds of facial fractures by 31% (OR .69, 95% CI .58 to .81, P < .001).
The study concludes that bicycle helmet use provides protection against severe TBI, reduces facial fractures, and saves lives even after sustaining an intracranial hemorrhage.
