Sponsor Decision

To quantify potential short- and long-term benefits of robotically-guided minimally invasive (MIS) or open-approach spine surgery in adult patients undergoing multi-level spinal instrumentation surgery, in comparison to image- or navigation-guided instrumentation in a matching cohort of control patients, performed using a freehand technique, both in MIS and open approaches.

Inclusion Criteria:

1. Adult patients (age 21 years and older), undergoing long (5 consecutive vertebrae or more) spinal fusion surgery, between T1 to the sacrum.
2. Cases may include surgeries involving iliac screws (e.g., Galveston technique or S2AI screws) although these screws will not be included in the data analysis.
3. Cases may include augmented cases (when one or more of the screws are inserted into vertebrae after a vertebral augmentation procedure, such as kyphoplasty or vertebroplasty).
4. Patient capable of complying with study requirements
5. Signed informed consent by patient

Exclusion Criteria:

1. Infection or malignancy
2. Primary abnormalities of bones (e.g. osteogenesis imperfecta)
3. Primary muscle diseases, such as muscular dystrophy
4. Neurologic diseases (e.g. Charcot-Marie Tooth, Guillain-Barre syndrome, cerebral palsy, spina bifida, or neurofibroma)
5. Spinal cord abnormalities with any neurologic symptoms or signs
6. Spinal cord lesions requiring neurosurgical interventions, such as hydromyelia
7. Paraplegia
8. Patients who have participated in a research study involving an investigational product in the 12 weeks prior to surgery
9. Any other significant disease or disorder which, in the opinion of the Investigator, may either put the participants at risk because of participation in the study, or may influence the result of the study.
10. Pregnancy
11. Patient cannot follow study protocol, for any reason
12. Patient cannot or will not sign informed consent

Adult patients (age over 21 years) undergoing long (5 or more consecutive vertebrae) open or minimally invasive instrumentation, correction and fusion sugery in the thoracic, lumbar or sacral spine who have been found to have kypho/scoliotic curve, sagittal or coronal imbalance or a combination of these.
