Brief Summary:
The main objectives of the study are to evaluate the acceptance into operating flow, performance and safety of the AQrate Robotic Assisted System during the spinal fusion surgery

Condition or disease Intervention/treatment Phase
Degenerative Disc Disease Spinal Stenosis Spondylolisthesis Spondylosis Device: AQrate Robotic Assistance System Not Applicable

Detailed Description:

Based on the literature review of similar devices and on the pre-clinical tests performed with the AQrate System on bench and cadavers, the study is build around the following hypothesis:

  1. The design and principle of operation of the AQrate System permits a correct integration in the surgical procedure flow thus enabling the surgeon to benefit from its advantages while not generating any additional operational difficulties
  2. The stability and ease of use of the device will permit the surgeon to achieve any planned spinal fusion without requiring additional assistance from the medical staff compared to a conventional spinal fusion surgery.
  3. A spinal fusion surgery procedure that is performed with the use of the AQrate System is similar to conventional spinal fusion surgery. If correctly used, no additional adverse event should be observed.
  4. The exposure to x-ray should decrease as the need of intraoperative recheck of pedicle screws placed should be reduced
  5. The precision of placement of pedicle screw should not be adversely affected by the use of the system compared to conventional spinal surgery.

Arm Intervention/treatment
Experimental: Device: AQrate Robotic Assistance System
Precise positioning of surgical instruments and spinal implants during general spinal surgery.
Device: AQrate Robotic Assistance System
Robotic guidance during spinal fusion surgery

Primary Outcome Measures :
  1. clinical acceptance of the performance of the AQrate Robotic Assistance System. [ Time Frame: Day of surgery ]
    The acceptance of the performance of the AQrate System will be measured by scale given to total of 8 questions.

Secondary Outcome Measures :
  1. Intraoperative exposure to radiation [ Time Frame: Day of surgery ]
    Exposure of radiation in seconds from O-arm or other imaging system used during surgery

  2. Accuracy of spinal screws placed [ Time Frame: Within one month of surgery ]
    The assessment of the accuracy of pedicle screw will be evaluated post operatively on the CT scan, at discharge with the Gertzbein grading scale and copared to a freehand technique
