Congenital absence of part of the anterior arch of the atlas, a rare disorder, was observed in two patients. The defect in the C1 cervical vertebrae, caused by congenital nonfusion of the arch of C1, may be confused with a cervical spinal fracture on plain radiographs of the cervical spine. The diagnosis is established by characteristic radiological changes, especially in the CT scan and bone scan. Because congenital anomalies of the cervical spine may predispose to instability of the cervical spine and can be confused with traumatic lesions, thorough evaluation is warranted. Treatment should be based on signs of instability, if present.
在两名患者中观察到寰椎前弓部分先天性缺失，这是一种罕见的病症。C1颈椎的缺损是由C1椎弓先天性未融合引起的，在颈椎X线平片上可能会与颈椎骨折相混淆。通过特征性的放射学改变来确诊，尤其是在CT扫描和骨扫描中。由于颈椎先天性异常可能易导致颈椎不稳定，并且可能与创伤性病变相混淆，因此有必要进行全面评估。如果存在不稳定迹象，治疗应基于这些迹象。
