The geometry of the lumbosacral region has been suspected to play a role in the development of degenerative lumbosacral stenosis in the dog. In this study, 50 dogs (21 German Shepherd dogs and 29 dogs of other breeds) with clinical signs of cauda equina compression were studied by magnetic resonance (MR) imaging. The orientation of the articular process joints in the L5-S1 region and the angle difference between two adjacent motion segments were calculated. Intervertebral disc degeneration of the same region was identified and classified in four stages. A positive association between MR-imaging stage and articular process joint angle difference in the transverse plane was found in the two groups of animals. German Shepherd dogs and dogs of other breeds had different geometry of the lumbosacral region with different articular process joint angles in the transverse plane and statistically different stages of disc degeneration.
腰荐部的几何结构被怀疑在犬退行性腰荐部狭窄的发生中起作用。在本研究中，对50只出现马尾神经压迫临床症状的犬（21只德国牧羊犬和29只其他品种犬）进行了磁共振（MR）成像研究。计算了L5 - S1区域关节突关节的方向以及两个相邻运动节段之间的角度差。对同一区域的椎间盘退变进行识别并分为四个阶段。在两组动物中均发现MR成像阶段与关节突关节在横平面的角度差呈正相关。德国牧羊犬和其他品种犬的腰荐部几何结构不同，横平面的关节突关节角度不同，椎间盘退变阶段在统计学上也不同。
