The purpose of this review article is to summarize the epidemiology, pertin
ent anatomy, mechanisms of injury, and classification systems of occipital
condylar fractures (OCFs), as well as their clinical presentation and scree
ning, the importance of computed tomography (CT) for detection, and current
treatment options. The authors emphasize the rate of occurrence of OCFs, w
hich may be detected in as many as 16% of patients with craniocervical inju
ry. Clinical presentation is not specific, and OCF is not readily diagnosed
at physical examination. Failure to diagnose may result in substantial mor
bidity, and thus accurate diagnosis is mandatory for both therapeutic and m
edicolegal implications. The diagnosis is most likely to be made with CT. T
hin-section CT technique is the method of choice to evaluate the traumatize
d craniocervical junction. OCFs should be suspected in all patients sustain
ing high-energy blunt trauma to the head and/or upper cervical spine, resul
ting from axial loading, lateral bending and/or rotation, and/or direct blo
w. Besides a CT study assessing potential intracranial injuries, these pati
ents require CT of the craniocervical junction. Radiologists should be awar
e of the types of OCFs and associated injuries.
