A retrospective clinical review of patients with atlanto-occipital dislocations.
To determine if fusion of the occiput to C1 can be accomplished without extension to the axis.
Patients with atlanto-occipital dislocations who have preservation of spinal cord function are quite rare. The standard approach to stabilization has been fusion of the occiput to the axis (C2). This may compromise rotation unnecessarily, however. The authors investigated the success of attempting to fuse only the occiput to C1 in children.
Two children with atlanto-occipital dislocation who had normal neurologic function underwent fusion from the occiput to the atlas after reduction.
Both cases showed successful fusion with no unwanted extension to lower levels. Full head rotation was preserved.
This technique restores stability without restricting rotation.
对寰枕关节脱位患者进行回顾性临床研究。
确定枕骨与C1融合而不延伸至枢椎是否可行。
脊髓功能保留的寰枕关节脱位患者非常罕见。标准的稳定方法是枕骨与枢椎（C2）融合。然而，这可能不必要地损害旋转功能。作者研究了在儿童中仅尝试枕骨与C1融合的成功率。
两名神经功能正常的寰枕关节脱位儿童在复位后接受了枕骨至寰椎的融合手术。
两例均显示融合成功，未向更低节段意外延伸。保留了头部的完全旋转功能。
该技术可恢复稳定性而不限制旋转功能。
