The atlantoaxial joints of a patient with lateral subluxation of the atlas were studied post mortem by dissection. There was severe erosion of the left lateral atlantoaxial joint and an asymmetrical erosion of the cartilages of the median atlantoaxial joint which prevented reduction of the lateral subluxation. The atlantoaxial ligaments were remarkably intact. It is emphasised that osseous factors rather than ligaments confer lateral stability to the atlantoaxial joints and that destruction of these leads to lateral subluxation.

对一名寰椎侧方半脱位患者的寰枢关节进行了尸体解剖研究。左侧寰枢外侧关节有严重侵蚀，寰枢正中关节软骨存在不对称侵蚀，这使得侧方半脱位无法复位。寰枢韧带显著完整。需要强调的是，赋予寰枢关节侧方稳定性的是骨性因素而非韧带，这些骨性结构的破坏会导致侧方半脱位。
