We report an 11-year-old girl who had previously undergone an operation for basilar invagination involving a foramen magnum decompression and midline wire fixation. After improving initially, her neurological condition worsened again. Repeated investigations showed a firm midline craniovertebral fixation and bone fusion. However, she was found to have a vertical mobile and reducible atlantoaxial dislocation. Treatment of the vertical dislocation by lateral mass fixation resulted in lasting relief from her symptoms. Vertical instability at the atlantoaxial joints needs to be identified and appropriately treated as it may be a cause of failure of midline fixation.
我们报告了一例 11 岁女孩，她曾因颅底凹陷症接受过枕骨大孔减压和中线钢丝固定手术。最初病情改善后，她的神经状况再次恶化。反复的检查显示中线颅颈固定和骨融合牢固。然而，她被发现存在垂直可移动和可复位的寰枢椎脱位。通过侧块固定治疗垂直脱位，使她的症状得到持久缓解。需要识别和适当治疗寰枢关节的垂直不稳定性，因为它可能是中线固定失败的原因。
