  3. Primary abnormalities of bones (e.g. osteogenesis imperfecta)
  4. Primary muscle diseases, such as muscular dystrophy
  5. Neurologic diseases (e.g. Charcot-Marie Tooth, Guillain-Barre syndrome, cerebral palsy, spina bifida, or neurofibroma)
  6. Spinal cord abnormalities with any neurologic symptoms or signs
  7. Spinal cord lesions requiring neurosurgical interventions, such as hydromyelia
  8. Patients who have participated in a research study involving an investigational product in the 12 weeks prior to surgery
  9. Patients requiring anterior release or instrumentation
  10. 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.

Study & Design

Study Type
OBSERVATIONAL
Study Design
Not specified
Primary Outcome Measures
NameTimeMethod
Revision surgeries1 year post-surgery

All cause revisions, including medical and surgical complications.

Secondary Outcome Measures
NameTimeMethod
Pedicle screw instrumentation accuracyWithin 1 year of surgery, if indicated by surgeon and clinically necessary

Accuracy will be quantified in millimeters and scored using the Gertzbein-Robbins classification, based on post-operative CTs that are clinically necessary for the management of the patient.

Ratio of executed vs. planned screwsDay of surgery

Number of screws planned to be robotically inserted and manually inserted instead, and cause.

Surgical complicationsWithin first year from day of surgery

Implant-related durotomy, infection requiring surgery, excessive blood loss, air emboli, new neural deficits, implant failure

Clinical performance of instrumentation techniqueDay of surgery

instrumentation time per screw, total surgery time, excluding: exposure and closure time, Surgeon-specific surgical techniques that impact surgery time

Improvement of radiographic and health-related quality of life metricsup to 10 years post-operative

post-operative radiographs and SRS22 questionnaire

Length of convalescencewithin 2 years of surgery

Length of hospital stay, destination at discharge, time to return to normal activities

Radiation ExposureDay of surgery

Reading of exposure in seconds (and KvP, if available) from C-arm or other imaging system used in the operating room.
