ABSTRACT
Imaging appearance and classification systems of ossification of the posterior longitudinal ligament (OPLL) on computed tomography and magnetic resonance imaging will be reviewed. Computed tomography evaluation most accurately demonstrates OPLL length and thickness, whereas magnetic resonance imaging has the advantage of demonstrating abnormal signal in the cord. Neurologic symptoms are most common in the cervical spine and are related to the degree of spinal stenosis and presence of cord edema. Surgical treatment usually involves cases of cervical OPLL and includes anterior or posterior decompression.

OBJECTIVE: Specific CT angiography (CTA) signs of vascular injury can be readily detected, and additional information regarding osseous and soft-tissue injuries can also be routinely obtained. In this article, we illustrate the important CTA signs of lower extremity vascular injury. CONCLUSION: CTA is efficient and accurate in the evaluation of clinically significant lower extremity arterial injuries after trauma.
