Outcome Measures

Primary Outcomes (1)

  • Accuracy of the screw implantation by Gertzbein-Robbins scale

    Mean and STD of Gertzbein-Robbins classification scale based on a low-dose post-operative CT scan

    Post-operative CT scan to be performed before hospital discharge and evaluation can be done right after or at the end of the of the data collection

Secondary Outcomes (2)

  • Evaluate radiation exposure dose and time in the operating room during the procedure in each study arm and comparatively.

    24 hours after surgery

  • Evaluate time-per-screw for the experimental device arm (PKS) arm.

    Values to be collected during each surgery once the last screw insertion is completed (1-2 hours within the surgery)

Study Arms (2)

Medical Device- PathKeeper System (PKS)

EXPERIMENTAL

One to ten-level posterior, open, instrumented spine surgery using unilateral or bilateral pedicle screw instrumentation under PKS intraoperative navigation guidance. Intervention: Medical Device - PKS. The PKS spine navigation system is for spatial positioning and orientation of surgical instruments during pedicle screw instrumentation in patients undergoing posterior fusion in single or multiple levels.

Device: Medical Device - PKS

2D Fluoroscopy

ACTIVE COMPARATOR

Control arm: Standard of care - free-hand technique guided by intra-operative 2D Fluoroscopy One to ten-level posterior, open, instrumented spine surgery using unilateral or bilateral pedicle screw instrumentation under free-hand technique guided by intra-operative 2D fluoroscopy

Device: Medical Device - PKS

Interventions

The PKS spine navigation system is for spatial positioning and orientation of surgical instruments during pedicle screw instrumentation in patients undergoing posterior fusion in single or multiple levels.
