BACKGROUND CONTEXT: Cervical spine injuries related to non-traditional modes of transportation represent an emerging source of morbidity in the United States, particularly among younger populations. Although cervical spine trauma has been extensively studied in traditional motor vehicle crashes, epidemiologic data regarding injuries associated with non-traditional vehicles remain limited.
PURPOSE: To characterize the epidemiology, mechanisms, demographics, and temporal trends of cervical spine injuries associated with non-traditional vehicles presenting to United States emergency departments.
STUDY DESIGN/SETTING: Descriptive epidemiological study utilizing the National Electronic Injury Surveillance System (NEISS), a nationally representative database of emergency department visits in the United States.
PATIENT SAMPLE: A total of 1,410 sampled NEISS records representing approximately 66,750 estimated emergency department visits for cervical spine injuries associated with non-traditional vehicles between January 1, 2015, and December 31, 2024.
OUTCOME MEASURES: Primary outcomes included injury diagnosis, mechanism of injury, patient demographics, vehicle type, injury location, disposition, and temporal trends in annual injury estimates.
METHODS: The NEISS database was queried for cervical spine injuries occurring between 2015 and 2024. Cases were identified using the neck body-part code and relevant diagnosis codes in combination with product codes for all-terrain vehicles (ATVs), dirt bikes, electric bicycles, go-carts, mopeds, minibikes, power-assisted cycles, and utility vehicles. Injury narratives were reviewed to confirm cervical spine involvement and classify mechanisms. National estimates and weighted percentages were calculated by summing the sampling weights provided for eligible NEISS records. No funds were received in support of this work ($0), and no study-specific conflicts of interest were identified.
RESULTS: The 1,410 sampled NEISS records represented approximately 66,750 estimated emergency department visits nationally. Cervical strain or sprain was the most common diagnosis (45.7% of the weighted national estimate), followed by cervical fracture (21.4%). Males accounted for 62.4% of the weighted estimate. Four-wheel off-road ATVs were the most frequently involved vehicle type (30.6%), followed by two-wheeled powered off-road vehicles (17.7%). Patients aged 11-20 years represented the largest age group (25.7%). Weighted annual estimates increased significantly during the study period, with an average increase of 564 visits per year (P = 0.011). Non-contact mechanisms, including loss of control, rollover events, and falls from vehicles, predominated across age and sex groups. Most estimated visits resulted in treatment and release from the emergency department (76.0%).
CONCLUSIONS: Non-traditional vehicles were associated with a substantial estimated burden of cervical spine injuries treated in United States emergency departments, particularly among adolescent and young adult males. ATVs and dirt bikes accounted for the largest shares of the weighted national estimate, and non-contact mechanisms predominated across demographic groups. These findings identify opportunities for targeted injury-prevention and safety interventions.
