Hip palpation has been used to provide semiquantitative information regarding passive joint laxity and susceptibility to hip dysplasia. The purpose of this study was to: (1) evaluate the intra- and inter-examiner repeatability of the hip reduction angle measured at 4 months of age by three examiners using manual goniometry and an electromagnetic tracking system; (2) compare the hip reduction angle measured with manual goniometry to the hip reduction angle measured with the electromagnetic tracking system; and (3) evaluate the hip reduction angle, distraction index and Ortolani manoeuvre at 4 months of age as predictors of the development of hip osteoarthritis at 12 months of age in 11 Labrador Retriever dogs. Intra- and inter-examiner repeatability was demonstrated for both the manual and electromagnetic goniometric measurement of the hip reduction angle (coefficient of variation < 4.3% and < 6.1%; and P = 0.163 and P = 0.836 respectively). The hip reduction angle measured by manual goniometry was moderately correlated to the hip reduction angle measured by the electromagnetic tracking system (r = 0.603, P < 0.0000). The hip reduction angle measured by manual and electromagnetic goniometry was a poor predictor of osteoarthritis at 12 months of age (r = 0.231, P < 0.062, and r = 0.321, P < 0.01). The distraction index was moderately correlated with the development of osteoarthritis by 12 months of age (r = 0.493, P < 0.0000). The Ortolani sign was sensitive (100%) but not specific (41%) for the development of osteoarthritis at 12 months of age. The hip reduction angle did not further quantify the Ortolani manoeuvre as a predictor of osteoarthritis in Labrador Retrievers.
髋关节触诊已被用于提供有关被动关节松弛度和髋关节发育不良易感性的半定量信息。本研究的目的是：(1) 评估三名检查者在4月龄时使用手动测角仪和电磁跟踪系统测量的髋关节复位角度的检查者内和检查者间重复性；(2) 比较使用手动测角仪测量的髋关节复位角度与使用电磁跟踪系统测量的髋关节复位角度；(3) 评估11只拉布拉多猎犬在4月龄时的髋关节复位角度、牵张指数和奥托拉尼手法，作为12月龄时髋关节骨关节炎发展的预测指标。髋关节复位角度的手动和电磁测角测量均显示出检查者内和检查者间的重复性（变异系数分别<4.3%和<6.1%；P = 0.163和P = 0.836）。手动测角仪测量的髋关节复位角度与电磁跟踪系统测量的髋关节复位角度呈中度相关（r = 0.603，P < 0.0000）。手动和电磁测角法测量的髋关节复位角度在12月龄时对骨关节炎的预测效果较差（r = 0.231，P < 0.062，以及r = 0.321，P < 0.01）。牵张指数与12月龄时骨关节炎的发展呈中度相关（r = 0.493，P < 0.0000）。奥托拉尼征对12月龄时骨关节炎的发展敏感（100%）但不特异（41%）。在拉布拉多猎犬中，髋关节复位角度并未进一步量化奥托拉尼手法作为骨关节炎预测指标的作用。
