BackgroundThough pedestrian versus motor vehicle (PVMV) accidents are a common cause of trauma admission and subsequent orthopaedic consult, the prevalence of upper extremity fracture (UEF) in such events and its association with lower extremity injury (LEI) is unknown. We sought to describe UEF in PVMV accident patients at the time of orthopaedic consult.MethodsA retrospective chart review was conducted for all pedestrian hit by motor vehicle cases for which an orthopaedic consult was performed at Jackson Memorial Hospital between July 2006 and January 2008. Fractures were recorded by location along with relevant clinical information. Logistic regression was used to calculate odds ratios (O.R.) and 95% confidence intervals (C.I.) for variables associated with UEF.Results336 cases were identified and reviewed. LEI was the most frequent injury type (67% of cases). UEF was also common, found in 25% of cases (humerus 11%, ulna 7%, radius 6%, hand 4%, and wrist 2%). Tibia or fibula fracture, femur fracture, and spine fracture were negatively associated with UEF in univariate analyses and after controlling for other associated factors.ConclusionsIn PVMV accident populations, UEF is a frequent injury often seen in the absence of any LEI. These findings emphasize the importance of carefully screening all PVMV accident patients for UEF and may call into question the usefulness of currently discussed injury pattern.
