Background: With the recent increase in size and horsepower of all-terrain vehicles (ATVs), it is imperative that preventable injuries be identified to protect the large population using ATVs. Currently, many states have no laws regulating ATV or helmet use. By identifying preventable injuries, the legislature can design appropriate laws to protect both children and adults.
Methods: A retrospective review of all patients with ATV injuries presenting between the years 2005 and 2010 was conducted. The data were grouped in several ways for analysis. This included age less than 9 years, weight less than 30 kg, crash at night, substance abuse, and presence of a helmet.
Results: There were 481 patients included in the study. Only 28 (8%) were using a helmet at the time of the crash. Helmet use was associated with less intracranial hemorrhage (3% vs. 22%, p = 0.01) and a decreased incidence of loss of consciousness (14% vs. 35%, p = 0.01). Patients testing positive for alcohol intoxication with or without drugs were significantly more likely to have intracranial hemorrhage, to crash at night, to have facial fracture, to have rib fracture, to arrive intubated, and to have a higher Injury Severity Score (ISS) (p < 0.01 for all).
Conclusion: With the recent increase in size and horsepower of ATVs, it is imperative that preventable injuries be identified to help protect a growing population of ATV operators. This study reveals a high rate of intracranial hemorrhage following an ATV crash in operators who do not use a helmet. Legislative efforts to implement strict helmet laws for ATV operators may be warranted.
Level of evidence: Prognostic study, level III.
