Abstract：
Canine hip dysplasia is a complex and multifactorial disease. The early diagnosis of dysplastic dogs under one year of age helps veterinarians to plan proper preventive/therapeutic methods. Having an accurate screening method increases the chance of the early detection of dysplasia. The goal of our study was to assess the inter-observer reliability of eight radiographic parameters in four-month-old Rottweilers. Radiographs of the 28 Rottweilers were investigated by five experienced observers. The radiographs were taken in ventrodorsal view with extended legs, frog-leg ventrodorsal view, distraction view, and dorsal acetabular rim view. Four quantitative parameters such as Norberg angle (NA), distraction index (DI), dorsal acetabular rim slope (DARS), and center edge angle (CEA) and four qualitative parameters such as sclerosis of the cranial acetabular rim (SCAR), location of the center of the femoral head (LCFH), grading of the degenerative joint disease (GDJD), and grading of the dorsal acetabular rim (GDAR) were evaluated. High inter-observer agreements were recorded for quantitative values, whereas the inter-observer agreement of the qualitative parameters was low. It can be deduced that the evaluated quantitative parameters are reliable, and a combination of these methods with clinical examinations might increase the accuracy of the examinations.
摘要：
犬髋关节发育不良是一种复杂的多因素疾病。一岁以下发育不良犬的早期诊断有助于兽医计划适当的预防/治疗方法。具有准确的筛查方法增加了早期发现发育异常的机会。我们研究的目的是评估四个月大的罗威纳犬的八个射线照相参数的观察者间可靠性。五名经验丰富的观察员调查了28只罗威纳犬的射线照片。射线照片是在腹背视图中用伸展的腿拍摄的，青蛙腿腹背视图，分心的观点，和髋臼背侧边缘视图。四个定量参数，如诺伯格角(NA)，分心指数(DI)，髋臼背侧边缘坡度（DARS），和中心边缘角（CEA）和四个定性参数，例如颅骨髋臼边缘硬化（SCAR），股骨头中心的位置（LCFH），退行性关节病（GDJD）的分级，评估髋臼背侧边缘（GDAR）的分级。记录了高观察员之间的协议的数量值，而观察者之间对定性参数的一致性较低。可以推断，评估的定量参数是可靠的，将这些方法与临床检查相结合可能会提高检查的准确性。
