Patient Positioning in Lumbar Fusion Surgery and Its Impact on Spinal Sagittal Balance and Surgeon Satisfaction

Hyperlordotic positioning will be achieved through pelvic pads positioned low on iliac crest to maximize lumbar hyperlordosis and increased hip flexion with as many pillows as tolerated at thighs and knees to allow for increased sacral slope. Regular position will involve the pelvic pads at above or iliac crest and without extra pillows at thighs and legs.
