Symptomatic canal stenosis at the level of atlas (C1) without atlantoaxial dislocation is thought to be very rare in children. Though common, anomalies of the arch of atlas are generally incidental findings in X-rays. High cord compression due to a narrow canal from a bifid posterior arch, or an absent posterior arch, is a very rare condition. We report 5 children with high cord compression from stenosis of C1 arch.
寰椎（C1）水平出现症状性椎管狭窄且无寰枢椎脱位的情况在儿童中被认为非常罕见。虽然寰椎弓异常很常见，但通常是X线检查中的偶然发现。由双裂后弓或后弓缺如导致的椎管狭窄引起的高位脊髓压迫是一种非常罕见的情况。我们报告了5例因C1弓狭窄导致高位脊髓压迫的儿童病例。
