The researchers examined 30 studies that analyzed the use of conventional fluoroscopy, two-dimensional fluoroscopic navigation and three-dimensional fluoroscopic navigation. There were 1,973 patients involved in the studies and 9,310 pedicle screw insertions.
The researchers found:
• 68.1 percent accuracy with the conventional fluoroscopy
• 84.3 percent accuracy with 2D fluoroscopic navigation
• 95.5 percent accuracy with 3D fluoroscopic navigation
“Three-dimensional fluoroscopic image guidance systems demonstrated significantly higher pedicle screw placement accuracy than conventional fluoroscopy or 2D fluoroscopic image guidance methods,” the researchers concluded.
