Acute headache attributed to whiplash in arcuate foramen and non-arcuate foramen subjects.

Methods Retrospective study of 128 patients that suffered a whiplash. The presence or absence of AF was recorded after a radiographic study, as well as the presence or absence of acute headache after the whiplash. Results The frequency of AF was 17.2%. Patients with bilateral AF presented a significant (p = 0.000, Fisher’s test) increase in the frequency of acute headache (90.9%) in comparison with the non-AF group (5.7%). The ratio between the presence and absence of acute headache was 166.6 times higher (IC 95% 18.2–1526.22) in subjects with bilateral AF in comparison with non-AF subjects. Conclusions The presence of bilateral AF is associated to an increased frequency of acute headache after suffering a whiplash, information of interest for the attention to these patients.engjournal article1432-0932https://doi.org/10.1007/s00586-016-4856-yrestricted access572Acute headacheArcuate foramenCervical spineWhiplashAntropología biológica2402 Antropología (Física)
