Whiplash is a compression injury. It is not a flexion/extension or acceleration/deceleration injury. Following impact, the trunk is thrust upwards, against the inertia of the head. This causes compression into a sigmoid deformation of the cervical spine at about 110ms after impact. During the deformation, the lower cervical segments undergo abnormal rotation into extension. The anterior annulus fibrosis is strained, and the facet joints are impacted. Extension is completed as the base of the neck descends.[1]
Specific tissue damage are tears of the anterior anulus fibrosis, strain or tears of the facet joint capsules (rim lesions and avulsions), and impaction injuries of the facet joints. Impaction injuries include contusions of the intra-articular meniscoids with intra articular haemorrhage, and subchondral and transarticular fractures.[1]
Prognosis
There is good recovery after the first year, but then it tails off. At 24 months 14% have not fully recovered, and 4% are severely affected.[2]
