Laxity of canine hip joint in two positions with computed tomography.
Computed tomographic (CT) examination of 20 canine hip joints was carried out in two positions, normal-standing and weight-bearing. In normal (dorsal acetabular rim angle: DARA < 15 degrees ) or slightly abnormal (DARA, 15 degrees to 20 degrees ) hip joints, the values of parameters to laxity were evaluated as more severe in the weight-bearing position. Comparisons of results using various indicators, including the center distance (CD) index, dorsolateral subluxation score, and lateral center edge angle, revealed that the CD index may be a useful marker of functional laxity in the canine hip joint under CT scanning. Further, CT scanning in the weight-bearing position was more sensitive than in the normal-standing position for the detection of laxity in hips with normal or only slightly abnormal DARA.
