Anterior cervical discectomy and fusion (ACDF) is a common treatment for patients with diverse cervical spine pathologies. Despite its favorable outcomes, numerous complications are still existing. In this case report, we present a complication involving cage dislodgement following ACDF in a patient with cervical trauma. A 62-year-old man presented at our hospital with right arm weakness following a fall injury. Radiographic evaluation revealed a fracture of the right C5 lamina, a fracture of the C6 transverse process, and a ruptured disc with downward migration, leading to spinal cord compression and right foraminal stenosis. The patient underwent ACDF at the C5-6 level, resulting in improved symptoms and subsequent discharge. However, 2 months after, dislodgement of the cage occurred, leading to C5-6 spondylolisthesis. Nonetheless, no further deterioration of neurological function was observed. Without additional surgery, the patient's condition was monitored over the course of 1 year, during which time bone fusion was deemed to have successfully taken place. Routine X-rays are crucial for the regular monitoring of post-surgical ACDF patients, especially those with traumatic cervical injuries. If cage dislodgement and spondylolisthesis develop without worsening symptoms and with minimal impact on the spinal canal, close observation may be favored.
