They were younger (43.2 vs. 47.7 years, <jats:italic toggle=\"yes\">P<\/jats:italic> = 0.08) and more commonly involved in a motorized collision, (58.5% vs. 29.0%) and more often multiply injured: other orthopaedic injuries (66.2% vs. 31.0%) and other nonorthopaedic injuries (40.0% vs. 7.5%, all <jats:italic toggle=\"yes\">P<\/jats:italic> &lt; 0.001 vs. TAI).
