Fifty\u2010two corridors were drilled on the right and the left sides by using unilateral and bilateral designs, respectively. Planned and postoperative trajectories (entry point, exit point, angle) were compared to establish the accuracy. Statistical analysis was used for accuracy comparison between designs.

Two corridors breached outside the vertebra. For all guides, mean entry and exit point deviations were less than 1 and 2\u2009mm, respectively. The maximum entry or exit point deviation in both groups was 4.7\u2009mm.
