OBJECTIVE AND IMPORTANCE: A disadvantage of transarticular and C2 pedicle screws is vertebral artery (VA) injury as a result of screw misplacement. If unilateral occlusion of the VA is present, @entity1317 of the dominant side will cause fatal complications as a result of @entity1887 . Several authors have recently reported the usefulness of C2 laminar screws because of their safety on @entity1317 . We used transarticular and C2 laminar screws combined with the atlas hook in a @entity1 with C1-2 instability and unilateral VA occlusion, in order to reduce the risk of further @entity1317 . CLINICAL PRESENTATION: A 64-year-old @entity1 with @entity309 and @entity4048 . Preoperative MR angiography showed a left side VA occlusion. TECHNIQUE: The @entity1 underwent atlantoaxial, posterior fusion using a transarticular screw on the side of the occlusion and a C2 laminar screw on the dominant side combined with a bilateral atlas hook. The transarticular screw was inserted using a navigation system and image intensifier, and the laminar screw was inserted free hand. Bone grafting from the iliac crest was performed. CONCLUSION: Transarticular and C2 laminar screws fixation combined with the atlas hook in a @entity1 with unilateral VA occlusion is a useful technique, in order to reduce the risk of further @entity1317 .

Safety of atlantoaxial fusion using laminar and transarticular screws combined with an atlas hook in a XXXX with unilateral vertebral artery occlusion (case report).
