•  By use of an AP fluoroscopic image, key bony landmarks are identified:

– midline (spinous processes)

– pedicular line (lateral edge of the pedicle)

vertical

horizontal

– skin incision line

For laminectomies, the incision is made closer to the midline.

For fusions, the incision is made lateral to the midpedicular line (1.0 cm).

– The size of the skin incision is dependent upon the size of the final working portal (15-26 mm).
