Robot vs. freehand spine surgery: 5 key notes on 2 new studies

Spinal Tech

Data from two new clinical studies on the Mazor robotic technology were presented at the International Meeting on Advanced Spine Techniques” in Washington, DC.

The initial study examined the robotic-guided outcome for patients with adult degenerative spine procedures, comparing the open freehand approach to minimally invasive procedures using the robotic technology. There were 705 adult degenerative spine patients studied. Here are three key findings:

 

• Experienced surgeons can significantly reduce complications and revision surgery with the robotic guidance compared to fluoro-guidance for minimally invasive procedures
• There was a three-fold higher rate of complications in the freehand cases than the minimally invasive cases.
• Revision rates were 3.8 times higher in the freehand minimally invasive cases than cases using the robot.

 

The second study compared robotic guidance to freehand pedicle screw placement for minimally invasive lumbar surgery. The researchers found:

 

• Robotic guidance significantly reduced complications
• Revision rates were lower in the robotic guidance group
