하위 경추 신연-굴곡 손상에 대한 전방 유합술 후 발생한 골절 및 양측 후관절 탈구.

A bilateral facet dislocation after anterior cervical fusion with a plate in distraction-flexion injury without significant instability in plain radiography is very rare. This paper reports a case with a confirmed injury status (C6–7 and C7–T1) by magnetic resonance imaging and computed tomography with no visible fractures or displacement on plain radiography. Anterior cervical fusion (C6–T1) was performed with a cage and plate. On the other hand, three days later, C6–7 bilateral facet dislocation developed with severe neck and radiating pain, and posterior decompression and fusion were performed. [ABSTRACT FROM AUTHOR]
