The Influence of Wearing a Helmet on Facial Fractures Patterns in Injured Motorcycle Riders

ABSTRACT

PURPOSE: This study was undertaken in order to identify the influence of wearing a head protective device (helmet) on facial fracture patterns in injured motorcycle riders. METHODS: We retrospectively reviewed the medical records of patients who underwent facial bone computed tomography (CT) resulting from motorcycle riding injuries between May 2009 and July 2011. Data collected included age, gender, Glasgow Coma Scale (GCS), Revised Trauma Score (RTS), status of helmet use, alcohol intake, time of accident, seating position of the rider, traumatic head injury (THI) measure and facial fracture patterns. Facial fracture patterns were grouped as fracture of the upper-face (orbits), mid-face (maxilla, zygoma, nose) and lower-face (mandible). We assessed the association between facial fracture patterns and helmet use. RESULTS: Of the 180 patients included in this study, 163 (90.6%) were male, 60 (33.3%) suffered facial fracture, 85 (47.2%) wore a helmet and 30 (16.7%) suffered THI. Their mean age was 28.7+/-14.6 years. Between the helmeted and unhelmeted groups, there was statistically significant difference in age, GCS, RTS and THI. There was no significant association between wearing a helmet and type of facial fracture. Multivariate logistic regression analysis demonstrated that age was the only factor influencing helmet use. CONCLUSION: Wearing a helmet prevented traumatic head injury but did not prevent any particular type of facial fractures in the injured motorcycle riders assessed in this study.
