Clinical Trial: Robotic vs. Freehand Corrective Surgery for Pediatric Scoliosis
Study Status: Recruiting
Recruit Status: Recruiting
Study Type: Observational
Official Title: Multicenter, Prospective, Partially Randomized, Controlled Trial of Robotic-guided vs. Freehand Corrective Surgery for Pediatric Scoliosis
Brief Summary: To compare the accuracy and feasibility, curvature correction and clinical outcomes of pedicle screw instrumentation with versus without robotic guidance, in pediatric and adolescent scoliosis patients
Detailed Summary:
Sponsor: Mazor Robotics
Current Primary Outcome: Revision surgeries [ Time Frame: 1 year post-surgery ]
Original Primary Outcome:
- Clinical outcomes as measured on plain radiographs [ Time Frame: 2 years ]Curvature correction and shoulder balance
- Radiation exposure [ Time Frame: Day of surgery ]Reading of exposure in seconds (and KvP if available) from C-arm or other imaging system used in the operating room.
- Ratio of executed vs. planned screws [ Time Frame: Day of surgery ]number of screws planned to be robotically inserted and manually inserted instead and cause.
- Pedicle screw instrumentation accuracy [ Time Frame: Within 1 year of surgery, if indicated by surgeon and clinically neccessary ]Accuracy will be quantified in millimeters and scored using the Gertzbein-Robbins classification, based on postoperative CTs that are clinically necessary for the management of the patient.
- Surgical complications [ Time Frame: Within first year from day of surgery ]Implant-related durotomy, infection requiring return to surgery, excessive blood loss, air emboli, new neural deficits, implant failure
Current Secondary Outcome:
- Clinical performance of instrumentation technique [ Time Frame: Day of surgery ]instrumentation time per screw, total surgery time, excluding: exposure and closure time, Surgeon-specific surgical techniques that impact surgery time
- Neuromonitoring events [ Time Frame: Day of surgery ]
- Hypoplastic pedicles [ Time Frame: Day of surgery ]<4 mm in diameter
- Improvement of radiographic and health-related quality of life metrics [ Time Frame: up to 10 years post-operative ]post-operative radiographs and SRS22 questionnaire
- Length of convalescence [ Time Frame: within 2 years of surgery ]Length of hospital stay, destination at discharge, time to return to normal activities
- Clinical Outcomes as measured on plain radiographs [ Time Frame: 2 years ]Curvature correction and shoulder balance
- Radiation Exposure [ Time Frame: Day of surgery ]Reading of exposure in seconds (and KvP, if available) from C-arm or other imaging system used in the operating room.
