Predicting Multiplanar Cervical Spine Injury Due to Head-Turned Rear Impacts Using IV-NIC

This article discusses the possibility of sustaining multiplanar soft-tissue injury due to three-dimensional intervertebral motion that goes beyond physiological limit (whiplash). Research was conducted using a biofidelic whole human cervical spine model, with muscle force replication and surrogate head, in head-turned rear impacts. The research had three goals: 1) to correlate Intervertebral Neck Injury Criterion (IV-NIC) with multiplanar injury, 2) to determine the threshold for IV-NIC injury at each intervertebral level, and 3) to determine the when and how of the intervertebral motion that subsequently caused injury. The research showed that IV-NIC extension peaks correlated best with multiplanar injuries (P < 0.001). Injury thresholds for IV-NIC ranged between 1.1 at C0-C1 and C3-C4 to 2.9 at C7-T1. The correlation between IV-NIC and multiplanar injuries showed a direct link between three-plane intervertebral instability and head-turned rear impacts because of dynamic extension beyond physiological limit.
