Abstract

Atlantoaxial instability frequently causes extrinsic cervical myelopathy via anterior displacement of the posterior arch of the atlas. However, upper cervical myelopathy resulting from atlantodental osteo-arthritis with the hypertrophic dens due to atlantoaxial instability is very rare. We present a case of upper cervical myelopathy secondary to atlantoaxial instability and atlantodental osteoarthritis. Although there was no atlantoaxial subluxation on the flexion and extension radiographies, hypertrophic changes of the anterior arch of the atlas with the dens axis and a fusion of the atlanto-dental joint resulting from atlantoaxial instability were determined on computed tomography and magnetic resonance imaging.

摘要

寰枢椎不稳常通过寰椎后弓向前移位导致外在性颈髓病。然而,由寰枢椎不稳引起的齿突肥大性寰枢椎骨关节炎导致的上颈髓病非常罕见。我们报告一例继发于寰枢椎不稳和寰齿骨关节炎的上颈髓病病例。尽管屈伸位X线片上没有寰枢椎半脱位,但计算机断层扫描和磁共振成像显示存在寰椎前弓与齿状突的肥大性改变以及由寰枢椎不稳导致的寰齿关节融合。
