Spinal Disc Herniations in Occupants Involved in Frontal Impacts
Disc herniations in the spine are commonly associated with degenerative changes, and the prevalence increases with age. Though rare, spinal disc herniations can also be caused by trauma. With increasing number of older drivers on U.S. roads, there is an expected proportionate increase in clinical findings of disc herniations in occupants involved in vehicle impacts. Our goal in this study is to determine whether there is a causal relationship between frontal impacts and the occurrence of disc herniations in the occupants of these impacts. We further aim to determine the prevalence of different types of spinal injury and to evaluate the effects of crash severity and other parameters on different types of spinal injury in such impacts. Using data from the National Automotive Sampling System - Crashworthiness Data System (NASS-CDS) database from 1993 through 2014, we examined the reported occurrence of all spine injuries for adult occupants in frontal impact.
