Case report and brief literature review.
To describe a unique complication following C1/2 fusion in a pediatric patient.
Os odontoideum, if symptomatic or unstable, should be treated by internal fixation. Posterior instrumented fusion of the cervical spine is not an uncommon surgical procedure.
Direct observation and management of the patient during representation with postoperative complication.
This case report details the previously unrecorded and unusual migration of a fixation device through the skull into the brain and outlines its subsequent removal.
Failure of bony fusion can result in micromotion and subsequent migration of fixation device components. This can occur even if the screw fixation is apparently sound. Extended routine radiographic follow-up would identify migration earlier.

描述儿童 C1/2 融合术后的一种独特并发症。
如果有症状或不稳定的齿状突，应通过内固定治疗。颈椎后路器械融合并非一种不常见的手术。
直接观察和管理有术后并发症表现的患者。
本病例报告详细描述了一种以前未记录的、不常见的固定装置通过颅骨迁移至大脑的情况，并概述了其随后的移除。
骨融合失败可导致固定装置部件发生微动和随后的迁移。即使螺钉固定明显良好，也可能发生这种情况。延长常规影像学随访将更早发现迁移。
