California has ranked among the top five states for ORV-related injuries and deaths for the past decade. Because ORVs are frequently used in rural areas with greater social vulnerability, concerns exist that injuries disproportionately affect disadvantaged populations. This study evaluates whether ORV injury rates and severity are associated with the Centers for Disease Control and Prevention\u2019s Social Vulnerability Index (SVI) in Southern California.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We performed a retrospective cohort study of 574 adult ORV trauma patients treated at a single level 1 trauma center between 2019 and 2024. Home ZIP codes determined patient classification into Low (0-0.249), Low-Medium (0.25-0.49), Medium-High (0.5-0.749), and High (0.75-1) SVI groups. The Injury Severity Score (ISS), Glasgow Coma Scale (GCS), and Abbreviated Injury Scale (AIS) assessed injury severity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The cohort was predominantly male (88%) with a median age of 32 years (IQR 21.25). 388 (67%) patients reported helmet use. Extremity injuries were the most common (upper: 66% and lower: 52%), followed by thoracic injuries (42.3%). Most patients resided in High SVI ZIP codes (54.3%), with 25.5% in Medium-High, 15.1% in Low-Medium, and 5.1% in Low SVI areas (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; .001).
