摘要

寰枢椎脱位被认为是一种罕见的颈椎异常。根据其类型，它可能会也可能不会导致寰枢椎不稳定，这可能会导致前脱位（最常见的类型）或后脱位，后者极为罕见。寰枢轴后脱位尤其危险，因为它会通过各种机制逐渐导致脊髓病变，最终可能导致四肢瘫痪甚至死亡。

Dystopic Os Odontoideum With Chronic Posterior Atlantoaxial Subluxation: A Case Report.

Os odontoideum is considered a rare cervical spine anomaly. Depending on its type, it may or may not result in atlantoaxial instability, which can lead to anterior subluxation (the most common type) or posterior subluxation, with the latter being extremely rare. Posterior atlantoaxial subluxation is particularly dangerous, as it can progressively lead to myelopathy through various mechanisms and may ultimately result in quadriplegia or even death.
