The progression of hip dysplasia was investigated in 116 military working dogs. Serial pelvic radiographs were graded for degree of dysplasia and degenerative joint disease (DJD). Norberg angles, angles of inclination, and joint space widths were measured. There was a significant correlation between the Norberg angle and the degree of dysplasia (p less than 0.0001). Angles of inclination and joint space width measurements did not demonstrate a correlation to canine hip dysplasia. Dysplastic dogs had a significant estimated risk for development of DJD compared to normal dogs (p less than 0.0001; odds ratio of 70.2). Dogs with normal hip conformation at 24 months of age or older did not develop moderate nor severe DJD.
对116只军犬的髋关节发育不良进展情况进行了研究。对系列骨盆X光片的发育不良程度和退行性关节病（DJD）进行分级。测量了诺伯格角、倾斜角和关节间隙宽度。诺伯格角与发育不良程度之间存在显著相关性（p<0.0001）。倾斜角和关节间隙宽度测量结果与犬髋关节发育不良无相关性。与正常犬相比，发育不良的犬发生DJD的估计风险显著更高（p<0.0001；优势比为70.2）。24月龄及以上髋关节结构正常的犬未发生中度或重度DJD。
