This comparative study demonstrates that PLC injury reduces O-arm navigation accuracy in thoracolumbar fractures, suggesting repeat scans may be necessary.
PLC injury significantly compromises the accuracy of O-arm-guided pedicle screw placement in thoracolumbar fractures. Increased navigation errors and critical breaches were observed despite protocol adherence, likely because of segmental instability. Surgeons should consider repeat scans for accuracy.
