MIS ReFRESH: Robotic vs. Freehand Minimally Invasive Spinal Surgeries Surgeries
To quantify potential short- and long-term benefits of robotically-guided minimally invasive spine surgery (MIS) for adult patients with lower back degeneration, in comparison a matching group of control patients operated in a minimally invasive approach whether freehand or with image guidance or navigation techniques.
Degenerative Disc Disease
|Study Design:||Observational Model: Case Control
Time Perspective: Prospective
|Official Title:||Multi-center, Partially Randomized, Controlled Trial of MIS Robotic vs. Freehand in Short Adult Degenerative Spinal Fusion Surgeries|
- Intra-operative exposure to x-ray radiation [ Time Frame: Day of surgery ] [ Designated as safety issue: No ]Reading of exposure in seconds (and KvP if available) from C-arm or other imaging system used in the operating room.
- Surgical complications [ Time Frame: Within first year from day of surgery ] [ Designated as safety issue: No ]New neural deficits, implant-related durotomy, infection requiring return to surgery, hardware failure requiring removal, vertebral body fracture, failure to fuse
- Revision surgeries [ Time Frame: 2 years ] [ Designated as safety issue: No ]All cause revisions
- Pedicle screw instrumentation accuracy [ Time Frame: Within 1 year of surgery, if indicated by surgeon and clinically necessary ] [ Designated as safety issue: No ]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.
- Incidence of pseudoarthrosis (malunion) [ Time Frame: Within 10 years from surgery ] [ Designated as safety issue: No ]Failure of the operated spinal segment to fuse.
- Length of convalescence [ Time Frame: Within 2 years of surgery ] [ Designated as safety issue: No ]Length of stay at the hospital, destination at discharge, time to return to normal activities, time to return to work
- Times of intra-operative stages [ Time Frame: Day of surgery ] [ Designated as safety issue: No ]instrumentation time per screw, total surgery time
- Ratio of executed vs. planned screws [ Time Frame: Day of surgery ] [ Designated as safety issue: No ]number of screws planned to be robotically inserted and manually inserted instead and cause.
- Quality of life assessment [ Time Frame: Each visit up to 10 years ] [ Designated as safety issue: No ]Health related quality of life questionnaires, including: back and leg Visual Analog Scale (VAS), Oswestry Disability Index (ODI), European Quality % Dimensions (EQ-5D-5L)
