We compared clinical outcomes after ventral fixation in dogs with atlantoaxial instability (AAI) on the basis of the presence or absence of atlantooccipital overlapping (AOO). Of 41 dogs diagnosed with AAI and treated ventral fixation, 12 exhibited AOO (AOO group), whereas 29 did not (non-AOO group). The AOO group had significantly higher neurological scores before (P=0.024) and 1 month after (P=0.033) surgery compared with the non-AOO group; however, no significant differences were observed between the groups 2 months after surgery. The presence of complicating AOO affected the clinical signs for dogs with AAI, but did not directly affect the outcome of surgical stabilization of AAI.
我们根据是否存在寰枕重叠（AOO），比较了患有寰枢椎不稳（AAI）的犬类进行腹侧固定后的临床结果。在41只被诊断为AAI并接受腹侧固定治疗的犬中，12只出现AOO（AOO组），而29只未出现（非AOO组）。与非AOO组相比，AOO组在手术前（P = 0.024）和术后1个月（P = 0.033）的神经学评分显著更高；然而，术后2个月两组之间未观察到显著差异。复杂AOO的存在影响了AAI犬的临床症状，但并未直接影响AAI手术稳定的结果。
