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.
犬髋关节发育不良是一种复杂的多因素疾病。对一岁以下发育不良犬只进行早期诊断有助于兽医制定适当的预防/治疗方法。拥有准确的筛查方法可增加发育不良早期检测的机会。我们研究的目的是评估四个月大的罗威纳犬八个放射学参数的观察者间可靠性。由五位经验丰富的观察者对28只罗威纳犬的X光片进行研究。X光片拍摄体位包括双腿伸展的腹背位、蛙腿腹背位、牵引位和髋臼背侧缘位。评估了四个定量参数，如诺伯格角（NA）、牵引指数（DI）、髋臼背侧缘斜率（DARS）和中心边缘角（CEA），以及四个定性参数，如髋臼前缘硬化（SCAR）、股骨头中心位置（LCFH）、退行性关节病分级（GDJD）和髋臼背侧缘分级（GDAR）。定量值的观察者间一致性较高，而定性参数的观察者间一致性较低。可以推断，所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。
