Nontraumatic anteroposterior atlantoaxial subluxation (AAS) has been described in several rheumatic or inherited disorders, especially rheumatoid arthritis and to a lesser extent the inflammatory spondyloarthropathies. We describe AAS secondary to osteoarthritis (OA) of the cervical spine in a 76-year-old man and a 73-year-old woman with severe cervical OA, symptomatic C1-C2 facet joints, and signs of generalized OA. Only 6 similar cases exist in the literature. OA should be added to the causes of AAS, and conversely AAS should be assessed in cases with severe OA of the upper cervical spine.
非创伤性寰枢椎前脱位（AAS）已在多种风湿性或遗传性疾病中被描述，尤其是类风湿关节炎，在炎性脊柱关节病中也有较少报道。我们描述了一名76岁男性和一名73岁女性因颈椎骨关节炎（OA）继发的AAS，他们患有严重的颈椎OA、有症状的C1-C2小关节以及全身性OA的体征。文献中仅存在6例类似病例。OA应被纳入AAS的病因中，反之，对于上颈椎严重OA的病例应评估是否存在AAS。
