【 摘 要 】

References(14)Cited-By(6)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° ± 10.3 ° for LCEA, 18.5° ± 7.3 ° for DARA, 0.40 ± 0.17 for CD index and 102.7° ± 6.9° 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.
