Robotic navigation assistance for spinal fixation in Marfan syndrome: a case report addressing anatomical challenges

At the six-month and three-year follow-ups, the patient reported significant improvements in back pain and functionality, with imaging demonstrating progressive fusion without loosening of the implants. RNA effectively addressed the unique anatomical challenges of hypoplastic pedicles and sacral body scalloping in a patient with MFS-associated spinal deformity. This technology enabled an individualized surgical approach through preoperative planning of instrumentation at each spinal level, allowing for precise placement of juxtapedicular and S2AI screws to achieve stable fixation in anatomically constrained regions.
