ABSTRACT
STUDY

DESIGN:

A retrospective study.

OBJECTIVES:

This study was performed by probing vertebral artery injuries and their radiologic characteristics in cervical spine fractures, and analyzing MRI findings of vascular injuries. SUMMARY OF LITERATURE REVIEW Vertebral artery injuries are found relatively often in cervical spine fractures. MATERIALS AND

METHODS:

We evaluated 57 cases of cervical spine fractures that occurred beginning in June 2011 and ending in February 2003. The characteristics of each fracture were evaluated using conventional radiographs, CT, and MRI. The presence of a vertebral artery injury was based on the absence of signal void in multilevel transverse foramens.

RESULTS:

Twelve out of the 57 cases (21.1%) were found to have unilateral vertebral artery injuries. Clinically, impairment in cerebral circulation was not found. We found no statistical correlation between the signal change in the spinal cord and in the vertebral artery injury (P=0.424). We noted fractures of transverse processes in 7 cases, 6 of which showed vertebral artery injuries. Thus, the transverse process facture was associated with t vertebral artery injury (P=0.000). There seemed to be no relationship between the vertebral artery injury and each of following fracture level (P=0.416), fracture type (P=0.723) and severity of soft tissue injury (P=0.195).

CONCLUSIONS:

Unilateral vertebral artery injuries were frequently found in the cervical spine fractures. And of all radiographic factors associated with vertebral artery injury, only the presence of transverse process fracture was statistically significant. Absence of signal void at multi-section MR images is considered to be a useful guide to commence additional vascular evaluation.
