未经评估:被动髋关节松弛(PHL)被认为是犬髋关节发育不良(HD)的主要危险因素,在应力髋部射线照片中,使用分心指数(DI)。该研究旨在使用Trás-os-Montes和AltoDouro大学(DisUTAD)的臀部分散器将早期的PHL与晚期HD成绩联系起来。
未经证实:共有41只狗(82髋)接受了后续研究。首先,在4到12个月之间,使用DisUTAD髋关节牵引器对狗进行射线照相,并确定每个髋关节的DI。然后,12个月后,使用常规的髋关节腹背投影重新评估狗的HD,并使用国际妇科医生联合会(FCI)评分系统评估髋关节的HD。
未经评估:在FCI等级为A(n=28)的第二次检查中,狗的臀部B(n=11),C(n=22),D和E(n=21)的早期DI分别为0.32±0.1、0.38±0.08、0.50±0.12和0.64±0.11。使用一般线性模型单变量进行统计分析,以DI为因变量和FCI等级,侧和性别作为固定因素,事后Bonferroni校正检验显示FCI等级之间存在显着差异(p<0.05)。
UNASSIGNED:这些结果显示早期DI和晚期FCIHD等级之间存在关联,建议将DisUTAD用于早期犬HD诊断。
UNASSIGNED: Passive hip laxity (PHL) is considered the primary risk factor for canine hip dysplasia (HD) and is estimated, in stress hip radiographs, using the distraction index (DI). The study aimed to associate the early PHL using the hip Distractor of University of Trás-os-Montes and Alto Douro (DisUTAD) and the late HD grades.
UNASSIGNED: A total of 41 dogs (82 hips) were submitted to a follow-up study. First, between 4 and 12 months of age, dogs were radiographed using the DisUTAD hip distractor and were determined the DI for each hip joint. Then, after 12 months of age, dogs were reevaluated for HD using the conventional hip ventrodorsal projection and hips were evaluated for HD using the Fédération Cynologique Internationale (FCI) scoring system.
UNASSIGNED: Hips of dogs\' in the second examination with FCI grades of A (n=28), B (n=11), C (n=22), and D and E (n=21) had an early DI of 0.32±0.1, 0.38±0.08, 0.50±0.12, and 0.64±0.11, respectively. Statistical analysis using the general linear model univariate, with the DI as dependent variable and the FCI grades, side and sex as fixed factors, and the post hoc Bonferroni correction test showed significant differences among FCI grades (p<0.05).
UNASSIGNED: These results show the association between early DI and the late FCI HD grades and the DisUTAD is recommended for the early canine HD diagnosis.
