Whiplash Injury and Brain DamageExperimental whiplash injury in rhesus monkeys has demonstrated that experimental cerebral concussion, as well as gross hemorrhages and contusions over the surface of the brain and upper cervical cord, can be produced by rotational displacement of the head on the neck alone, without significant direct head impact. These experimental observations have been studied in the light of published reports of cerebral concussion and other evidence for central nervous system involvement after whiplash injury in man.

Coup and contre-coup injury: observations on the mechanics of visible brain injuries in the rhesus monkey✓ The distribution of coup and contre-coup contusions and subdural hematomas after frontal and occipital impacts has been studied in the rhesus monkey. The effect of skull fracture on these lesions is noted, and the data compared to known postmortem observations in man. The translation/cavitation theory for brain injury as presently conceived is not supported by these data. The skull distortion and head rotation hypothesis offers opportunities for developing a better theory for brain injury by direct as well as indirect impact. The significance of these observations for design of protective devices is briefly discussed.
