The American experience is different because road building is done with our own peculiar type of labor-saving equipment. More anomalous, however, is the likelihood of a rising incidence of spinous process fractures among passengers on our own superhighways, resembling those of the manual workers on the older GermanAutobahnen.3 Among 480 x-ray examinations of the neck in our files, 38 cases were found with isolated or multiple calcareous deposits or fragments near the cervicodorsal spinous processes. A history of an automobile collision was disclosed in 14 of these cases. Not
