A patient receiving lower back surgery typically lies in the prone position with an option of different variations, according to Pfiedler Enterprises. The body rests horizontally on the stomach with the head facedown and the arms draped along the side.
The Andrews Frame variation of the standard prone position provides direct access to the lower lumbar region of the spine, according to the University of Pittsburgh. The patient assumes a kneeling position with the arms extended to the side in an L-shape and the hands toward the head. Horseshoe headrests and other pillow cutouts allow the head to remain facedown with free range of movement for essential surgical tubes.
