The aims of this study were to evaluate the prevalence and anatomical characteristics of thoracic caudal articular process dysplasia in French bulldogs, English bulldogs and Pugs presenting for problems unrelated to spinal disease. In this retrospective cross-sectional study, computed tomography scans of the thoracic vertebral column of these three breeds were reviewed for the presence and location of caudal articular process hypoplasia and aplasia, and compared between breeds. A total of 271 dogs met the inclusion criteria: 108 French bulldogs, 63 English bulldogs, and 100 Pugs. A total of 70.4% of French bulldogs, 84.1% of English bulldogs, and 97.0% of Pugs showed evidence of caudal articular process dysplasia. Compared to French and English bulldogs, Pugs showed a significantly higher prevalence of caudal articular process aplasia, but also a lower prevalence of caudal articular process hypoplasia, a higher number of affected vertebrae per dog and demonstrated a generalized and bilateral spatial pattern more frequently. Furthermore, Pugs showed a significantly different anatomical distribution of caudal articular process dysplasia along the vertebral column, with a high prevalence of caudal articular process aplasia between T10 and T13. This area was almost completely spared in French and English bulldogs. As previously suggested, caudal articular process dysplasia is a common finding in neurologically normal Pugs but this also seems to apply to French and English bulldogs. The predisposition of clinically relevant caudal articular process dysplasia in Pugs is possibly not only caused by the higher prevalence of caudal articular process dysplasia, but also by breed specific anatomical characteristics.
本研究的目的是评估因非脊柱疾病问题前来就诊的法国斗牛犬、英国斗牛犬和哈巴狗胸椎尾侧关节突发育异常的患病率及解剖学特征。在这项回顾性横断面研究中，对这三个品种犬的胸椎计算机断层扫描图像进行了回顾，以确定尾侧关节突发育不全和发育不良的存在及位置，并在品种间进行比较。共有271只犬符合纳入标准：108只法国斗牛犬、63只英国斗牛犬和100只哈巴狗。共有70.4%的法国斗牛犬、84.1%的英国斗牛犬和97.0%的哈巴狗有尾侧关节突发育异常的迹象。与法国斗牛犬和英国斗牛犬相比，哈巴狗尾侧关节突发育不全的患病率显著更高，但尾侧关节突发育不全的患病率更低，每只犬受影响的椎骨数量更多，且更频繁地表现出广泛的双侧空间模式。此外，哈巴狗尾侧关节突发育异常在脊柱上的解剖分布明显不同，在T10至T13之间尾侧关节突发育不全的患病率很高。在法国斗牛犬和英国斗牛犬中，这个区域几乎完全没有受到影响。如先前所述，尾侧关节突发育异常在神经功能正常的哈巴狗中是常见的发现，但这似乎也适用于法国斗牛犬和英国斗牛犬。哈巴狗临床相关尾侧关节突发育异常的易感性可能不仅是由于尾侧关节突发育异常的患病率较高，还由于品种特异性的解剖学特征。
