Plain-English summary
A group of dogs with atlantoaxial instability (a condition affecting the neck) underwent surgery to stabilize their joints using two different techniques: polymethylmethacrylate fixation (PMF) and atlantoaxial plate fixation (APF). After the surgeries, the dogs were monitored for up to seven months. The results showed that while both techniques helped stabilize the joint, the APF method resulted in better bony fusion in most dogs compared to PMF. Overall, both methods were found to be safe and effective for treating this condition in dogs.

Abstract
We evaluated the completeness of bony fusion of the atlantoaxial joint (AAJ) through polymethylmethacrylate fixation (PMF) and atlantoaxial plate fixation (APF) using six canine models with dens partial resection. In both groups, the hydroxyapatite content at the AAJ was measured up to 7 months postoperatively using quantitative computed tomography. Histological assessment revealed fibrous fusion in the PMF group. Meanwhile, in the APF group, only one dog achieved fibrous fusion, whereas the remaining three showed bony fusion. To our knowledge, this study was the first to evaluate AAJ fusion histologically after PMF and APF. The present study demonstrates that PMF and APF may stabilize the AAJ without clinical complications. Therefore, PMF and APF are clinically useful fixation methods for atlantoaxial instability.
