Abstract：
OBJECTIVE: To describe the prevalence of elbow dysplasia (ED) in 13 dog breeds in France.
METHODS: A total of 18,870 elbow radiographs taken from 2002 to 2022 were evaluated by 2 independent examiners.
METHODS: For each breed, the incidence of each of the 4 International Elbow Working Group scoring classes was extracted from the database. Breeds were excluded if fewer than 150 radiographs had been read for that breed.
RESULTS: This study included 17,861 records for 13 dog breeds: American Akita, Alaskan Malamute, Old German Shepherd (Altdeutscher Schäferhund), American Staffordshire Terrier, Australian Shepherd, Belgian Shepherd, White Swiss Shepherd, Bernese Mountain Dog, Cane Corso, Czechoslovakian Wolfdog, Rhodesian Ridgeback, Rottweiler, and Dogue de Bordeaux. The overall prevalence of ED was 11.4%, ranging from 1.1% in the Czechoslovakian Wolfdog to 32.2% in the Dogue de Bordeaux. The Dogue de Bordeaux, Rottweiler, Bernese Mountain Dog, and Cane Corso breeds were most commonly affected by ED. The prevalence of ED was significantly higher in male dogs than in female dogs (17.5% vs 10.5%, P < .05). Joint incongruity and fragmented coronoid process were the 2 most common primary ED lesions identified. The prevalence of ED among the dogs evaluated decreased over the timeframe of the study.
CONCLUSIONS: The results of this study help to clarify the prevalence of ED in different breeds in France. These data should be interpreted with caution as this study included a small percentage of the total number of dogs born for each breed in France over the study period.

摘要：
目的：描述法国13个犬种的肘部发育不良（ED）的患病率。
方法：由2名独立检查者评估了2002年至2022年拍摄的18,870张肘部X光片。
方法：对于每个品种，我们从数据库中提取了4个国际肘部工作组评分班的发生率.如果该品种的X射线照片少于150张，则排除该品种。
结果：这项研究包括13个犬种的17,861条记录：美国秋田，阿拉斯加Malamute,老德国牧羊犬（AltdeutscherSchäferhund），美国斯塔福德郡梗，澳大利亚牧羊人,比利时牧羊人,白色瑞士牧羊犬,伯尔尼山的狗，CaneCorso,捷克斯洛伐克狼狗,罗得西亚脊背,罗威纳,还有波尔多的狗.ED的总体患病率为11.4%，从捷克斯洛伐克狼犬的1.1%到波尔多时尚的32.2%不等。波尔多警犬,罗威纳,伯尔尼山的狗，和甘蔗Corso品种最常受到ED的影响。雄性犬的ED患病率明显高于雌性犬（17.5％vs10.5％，P<0.05)。关节不协调和破碎的冠状突是确定的2个最常见的原发性ED病变。在研究的时间范围内，评估的狗中ED的患病率降低。
结论：这项研究的结果有助于阐明法国不同品种的ED患病率。这些数据应谨慎解释，因为这项研究包括在研究期间法国每个品种出生的狗总数的一小部分。
