In Miller 2025 et al., on spinal drill guide accuracy, what was the reported mean deviation between planned and actual screw entry/exit points?
A. Less than 2 mm
B. Between 2 and 4 mm
C. Between 4 and 6 mm
D. Over 6 mm
E. Zero deviation
Answer: Less than 2 mm
Explanation: The mean deviation was less than 1 mm across all entry and exit points, supporting guide accuracy.
In Miller 2025 et al., on spinal drill guide accuracy, what was a reported technical benefit of the SOP plate when used with the 3D-printed guides?
A. Required no dissection
B. Prevented any deviation
C. Acted as a reduction guide
D. Needed no screw tightening
E. Eliminated need for imaging
Answer: Acted as a reduction guide
Explanation: The plate helped realign vertebrae during screw placement, effectively serving as a reduction aid.
In Miller 2025 et al., on spinal drill guide accuracy, how long did it take to apply each drilling guide during surgery?
A. Less than 30 seconds
B. 1–2 minutes
C. 5 minutes
D. 10 minutes
E. Over 10 minutes
Answer: Less than 30 seconds
Explanation: Each vertebral guide took less than 30 seconds to place and drill, improving surgical efficiency.
In Miller 2025 et al., on spinal drill guide accuracy, what software was used to segment canine spines for guide creation?
A. 3D Studio Max
B. Blender
C. Slicer
D. Materialise Mimics
E. AutoCAD
Answer: Slicer
Explanation: 3D Slicer was used to segment CT data and generate 3D spinal models.
In Miller 2025 et al., on spinal drill guide accuracy, what was the Zdichavski classification for all screw placements?
A. Grade 1: Optimal placement
B. Grade 2a: Medial wall breach (partial)
C. Grade 2b: Medial wall breach (complete)
D. Grade 3a: Lateral wall breach (partial)
E. Grade 3b: Lateral wall breach (complete)
Answer: Grade 1: Optimal placement
Explanation: All 140 screw holes were classified as Grade 1, indicating fully contained, optimal placement.
