翼状靱帯損傷後の不安定性評価に頚椎開口位側屈撮影が有用であった1例

Key Points

• To assess the utility of dynamic imaging in evaluating instability after wing ligament injury in the acute phase.
• Conducted dynamic imaging in the open mouth position during acute care.
• Performed manual reduction of dislocation and monitored the patient post-accident.
• Evaluated instability through cervical X-ray and MRI analyses.
• Dynamic imaging revealed abnormal mobility between the odontoid process and the lateral masses, indicating instability.
• Manual reduction was successfully performed, and by 6 weeks, the patient was independent in daily activities with controlled neck pain.
• MRI showed poor visualization of the left wing ligament, highlighting challenges in assessment.
