This trial will prospectively evaluate screw deviation from pre-planned trajectory using the standard of care Mazor X robotic system. Patients undergoing posterior thoracolumbar arthrodesis procedures utilizing pedicle screw instrumentation at previously uninstrumented levels for degenerative conditions, spinal deformity, spinal infection, trauma, or neoplastic processes between T2-S1 will be asked to participate in this prospective cohort study.~This single centered study will enroll up to 50 patients to achieve a total number of 250 screws for assessment. Subjects will be followed till discharge following surgery. All subjects enrolled in the study will be recruited from a pool of subjects eligible for posterior thoracolumbar arthrodesis surgery.
The purpose of the study is to assess screw deviation from pre-planned trajectory using the Mazor X robotic system in patients undergoing posterior thoracolumbar arthrodesis procedures between T2-S1.
