Résumé
Cervical facet dislocations are rare in patients sustaining traumatic subaxial injuries. They occur due to hyperflexion-distraction and can occur unilaterally or bilaterally resulting in significant spinal instability. Bilateral facet dislocations at one level are less common than unilateral dislocations, while bilateral facet dislocations at adjacent spinal levels have only been reported twice in literature. A 31-year-old male presented with bilateral facet dislocations at two adjacent cervical levels (C6/C7 and C7/T1) following a fall from 40 to 50 feet. The patient had undergone a C6/C7 disk arthroplasty a few weeks before the traumatic event. Here, we present the unique case of cervical bilateral jumped facets occurring at two adjacent levels (i.e., C6-C7 and C7-T1). Notably, the antecedent cervical C6-C7 arthroplasty likely contributed to the altered load distribution, leading to this unusual instance of bilateral adjacent level facet dislocations. In such cases, surgical reduction and fixation may prove technically challenging warranting, therefore, careful preoperative planning.

CASE DESCRIPTION
METHODS
A 31-year-old male presented with bilateral facet dislocations at two adjacent cervical levels (C6/C7 and C7/T1) following a fall from 40 to 50 feet. The patient had undergone a C6/C7 disk arthroplasty a few weeks before the traumatic event.
CONCLUSION
CONCLUSIONS
Here, we present the unique case of cervical bilateral jumped facets occurring at two adjacent levels (i.e., C6-C7 and C7-T1). Notably, the antecedent cervical C6-C7 arthroplasty likely contributed to the altered load distribution, leading to this unusual instance of bilateral adjacent level facet dislocations. In such cases, surgical reduction and fixation may prove technically challenging warranting, therefore, careful preoperative planning.
