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

Study design: Case Report
Abstract: Background: Patients with Marfan syndrome (MFS) can experience spinal deformity characterized by thoracolumbar kyphoscoliosis, severe spondylolisthesis, dural ectasia, vertebral body scalloping, and hypoplastic pedicles. These unique anatomical features complicate conventional spinal instrumentation techniques, rendering robotic navigation assistance (RNA) a viable option in such cases. Case Description: stage occurred one month postoperatively and involved a L3-L5 lateral lumbar interbody fusion (LLIF) and a L5-S1 anterior lumbar interbody fusion (ALIF), also guided by RNA. Conclusions: 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.
