A fracture of unilateral pars interarticularis of the axis: a case report.
OBJECTIVE
To present a case of a fracture of the unilateral pars interarticularis of the C2.


METHODS
There is confusion in the use of anatomic terminology of the pars interarticularis and pedicle of the C2 in literature. A fracture of the unilateral pars interarticularis of the C2 was diagnosed and treated nonsurgically by a Philadelphia collar.


RESULTS
The patient was free of pain and obtained a full range of motion.


CONCLUSIONS
The presumed mechanism of injury in the fracture described here was hyperextension and axial loading.
