The purpose of this study was to obtain the computed tomography (CT) data for the hip joints of 22 Border Collies. The dorsolateral subluxation (DLS) score, lateral center edge angle (LCEA), dorsal acetabular rim angle (DARA) and center distance (CD) index were measured on the CT images in a weight-bearing position. Radiographic Norberg angle (NA) was also measured. The mean values were 45.7 +/- 10.2% for DLS score, 85.9 degrees +/- 10.3 degrees for LCEA, 18.5 degrees +/- 7.3 degrees for DARA, 0.40 +/- 0.17 for CD index and 102.7 degrees +/- 6.9 degrees for NA. Since the DLS score and LCEA showed strong correlation, combined use of these parameters might improve diagnostic accuracy. We consider CT evaluation in a weight-bearing position to be a useful method for multidirectional evaluation of hips.
本研究的目的是获取22只边境牧羊犬髋关节的计算机断层扫描（CT）数据。在负重位的CT图像上测量背外侧半脱位（DLS）评分、外侧中心边缘角（LCEA）、髋臼背侧缘角（DARA）和中心距离（CD）指数。还测量了X线Norberg角（NA）。DLS评分的平均值为45.7±10.2%，LCEA为85.9°±10.3°，DARA为18.5°±7.3°，CD指数为0.40±0.17，NA为102.7°±6.9°。由于DLS评分和LCEA显示出强相关性，联合使用这些参数可能会提高诊断准确性。我们认为负重位的CT评估是一种用于髋关节多方向评估的有用方法。
