Navigation-assisted C1-ring osteosynthesis for an unstable atlas fracture: a case report

Navigation-assisted ORIF of unstable C1 fractures is a safe, effective, and motion-preserving strategy that achieves reliable reduction and stabilization. It represents a valuable alternative to fusion procedures in young patients in whom fusion carries very high morbidity. Stereotactic navigation enhances the accuracy and safety of lateral mass screw placement and may reduce complication risk. This case adds to the growing literature supporting posterior C1-ring osteosynthesis as a safe approach for select unstable atlas fractures.
