Could the Intraoperative Radiation Exposure (Fluoroscopy) of Percutaneous Pedicle Screw Fixation be Reduced Using an Electronic Conductivity Device?

Could the Intraoperative Radiation Exposure (Fluoroscopy) of Percutaneous Pedicle Screw Fixation be Reduced Using an Electronic Conductivity Device? A Prospective, Randomized Study

To compare classical pedicle finder versus pedicle finder with impedancemetry on the perioperative radiation exposure of PPTLO. These two devices are already used in common practice.

Inclusion Criteria:

• Men and women between 18 and 80 years-old;
• Patient with an indication of PPTLO for one or two segments
• Patient in a position to understand protocol information;
• Patient who received information about the protocol and who did not show opposition to participate

Exclusion Criteria:

• History of posterior spinal fusion surgery on the spinal level concerned by the study;
• Morbid obesity (body mass index greater than 35 kg / m²);
• Major incapable (safeguard of justice, guardianship) and persons deprived of liberty.
• Simultaneous participation in another research protocol involving the human person
