Ilio-sacral screws used in pelvic fixation for neuromuscular scoliosis (early onset or extremely frail patients) are difficult to position. We reviewed 10 patients (20 implants) operated on with iliosacral screw insertion using robotic assistance. The trajectory planned was compared with the iliosacral screws; actual real position using pre- and post-surgery flat-panel CT images. All the screws were perfectly located within the sacrum. Robot-assisted implantation was associated with a high level of agreement between the planned and achieved screw positions.
