Orthopedic Considerations in the Pedestrian versus Motor Vehicle Accident Polytrauma Patient

Pedestrian versus motor vehicle accidents (PVMVAs) are a common cause of morbidity and mortality around the globe. Past models of PVMVAs assume lower-extremity vehicle contact as the initiating event, with a subsequent predicted injury sequence consisting of a lower extremity injury followed by injury to the body, head, and upper extremities. The term "fatal triad" was first coined by Farley, which described concomitant injuries to the skull, pelvis, and extremity fractures. Over the years, this once well-accepted model of injury has been under scrutiny by numerous orthopedic researchers, and it has lost credibility. This case presentation glaring reveals that the patient incurred which is referred to as the "fatal triad", in contrast to the commonly circulated thoughts of biodynamic mechanisms of PVMVA fractures. More research in this arena is warranted. This lack of information contributes to the morbidity and mortality associated with such devastating injuries. The overlying theme displayed in the data analyzed in this paper demonstrates the vital importance of the orthopedic surgeon in the management of the PVMVA patient. No matter the particular mechanism of injury, occurrence, or agreed-upon treatment protocol, the role of the orthopedic physician is instrumental to the wellbeing of the PVMVA trauma patient.
