Positioning for midline approach (posterior procedures)
The patient is positioned onto a radiolucent table prone on two horizontally placed padded bolsters (one at the level of sternum and another one at the level of anterior iliac spine) or a frame.
- The abdomen should hang free to avoid increased intraabdominal pressure to prevent excessive bleeding
- Adequate padding needs to be provided to elbows and knees to avoid pressure sores
- The head is rested either in a padded head holder or a Mayfield rest to avoid pressure on the eyes.
Make sure that there are adequate personnel to receive and turn the patient from supine to prone position on the operating table.
