From: Comparison of three imaging and navigation systems regarding accuracy of pedicle screw placement in a sawbone model

Figure 5

Mean distance to lateral and medial pedicle cortex with 95% confidence interval as assessed by the observers dependent on the combination of imaging system and navigation system used. The measurements from both observers are displayed resulting in two data points for each screw. The screws in the area marked in red represent the clinically relevant perforations.
