Current Perspectives on Percutaneous Vertebroplasty: Current Evidence/Controversies, Patient Selection and Assessment, and Technique and Complications
Figure 3
Spot fluoroscopic images from two separate patients obtained during PV. (a) demonstrates left bone cannula insitu. The right pedicle has been cannulated, and is advanced in the AP plane staying clear of the pedicle medial cortical margin. Arrow indicates the medial pedicle cortex. (b) Lateral projection demonstrates tip of needle anterior to posterior vertebral cortex (dashed white line). Once this landmark is reached, the cannula can be safely advanced to 1 cm posterior to the anterior vertebral cortex under lateral projection fluoroscopic guidance. Cementing is also performed in this projection.
