CT-assisted percutaneous anterior cordotomy: technical note

Percutaneous radiofrequency cordotomy remains a useful modality for managing selected patients with unremitting pain due to malignancy. Although the lateral C1-C2 method is widely used, certain clinical situations may call for a low anterior cervical approach via the disc space. The anterior method can be technically exacting due to the need for precision in the angle of approach at the point of disc space entry. Here we describe how CT-imaging can be used to simplify target localization during percutaneous anterior cervical cordotomy.
