Résumé
Perched facet joint syndrome is a common post-traumatic condition encountered at the level of subaxial cervical spine in acute settings but more rarely found in a chronic manner. We define this dislocation as old subaxial cervical facet dislocation (OSCFD) when adequate treatment is not established within 3 weeks after initial trauma. It is a clinical entity, moreover, associated with significant impact on neurologic functions such as nerve root or spine compression. Many factors are attributed to explain delayed diagnosis, such as living in a developing country, misreading or inadequate imaging, the presence of multiple injuries, or an absence of symptoms at the time of trauma. We report 2 typical examples of long-lasting OSCFD (up to 6 months), treated both by an anterior cervical approach but with 2 different surgical strategies, associated with similar subsequent clinical restoration and neuroradiologic realignment. We also review the related literature regarding the mechanisms underlying this unusual observation and varied surgical strategies adopted, finally explaining the reasons for our choosing the always-anterior strategy. In OSCFD, performing a vertebral canal decompression and realignment of the cervical spine column is crucial. More options are purposed to treat this challenging condition, and more of them could be complicated by time-consuming resetting in the operating room, prolonged anesthesiologic procedures, and elevated risk of 360° instrumentation surgical maneuvers. The one-stage combined anterior-approach only (corpectomy or discectomy) is an effective, fast, and safe surgical strategy for treating OSCFD.

BACKGROUND
Perched facet joint syndrome is a common post-traumatic condition encountered at the level of subaxial cervical spine in acute settings but more rarely found in a chronic manner. We define this dislocation as old subaxial cervical facet dislocation (OSCFD) when adequate treatment is not established within 3 weeks after initial trauma. It is a clinical entity, moreover, associated with significant impact on neurologic functions such as nerve root or spine compression. Many factors are attributed to explain delayed diagnosis, such as living in a developing country, misreading or inadequate imaging, the presence of multiple injuries, or an absence of symptoms at the time of trauma.
CASE DESCRIPTION
We report 2 typical examples of long-lasting OSCFD (up to 6 months), treated both by an anterior cervical approach but with 2 different surgical strategies, associated with similar subsequent clinical restoration and neuroradiologic realignment. We also review the related literature regarding the mechanisms underlying this unusual observation and varied surgical strategies adopted, finally explaining the reasons for our choosing the always-anterior strategy.
CONCLUSIONS
In OSCFD, performing a vertebral canal decompression and realignment of the cervical spine column is crucial. More options are purposed to treat this challenging condition, and more of them could be complicated by time-consuming resetting in the operating room, prolonged anesthesiologic procedures, and elevated risk of 360° instrumentation surgical maneuvers. The one-stage combined anterior-approach only (corpectomy or discectomy) is an effective, fast, and safe surgical strategy for treating OSCFD.
