The literature review includes a short anatomical description of the lumbosacral area, etiology, symptoms, diagnosis and therapy of CECS. Two hundred and twenty-seven large-breed dogs were examined clinically, neurologically and radiologically for diseases of the lumbosacral area. Radiological findings, such as dorsal dislocation of L7, spondylosis deformans, sloped craniodorsal contour of S1, sclerosis of the cranial plate of S1 as well as narrowing and increased density of the intervertebral foramen L7/S1 were compared with clinical and neurological results. In 15 dogs dorsal dislocation of L7 by 1 to 8 mm was found. An extended position proved to be more successful in demonstrating that finding than the flexed one. All other pathological changes were found either individually or in combination in patients with lumbosacral spondylolisthesis. One hundred and thirty-six dogs showed no sign of dorsal dislocation but all the other described changes. All detected changes have to be interpreted as instability of the lumbosacral area and resultant chronic and degenerative pathological processes. A definite correlation between spondylolisthesis of L7/S1 and compression of the cauda equina could not be found on plain radiography.
文献综述包括腰骶部的简短解剖描述、马尾综合征的病因、症状、诊断和治疗。对227只大型犬进行了腰骶部疾病的临床、神经学和放射学检查。将放射学检查结果，如L7背侧脱位、脊柱畸形、S1颅背侧轮廓倾斜、S1颅板硬化以及L7/S1椎间孔变窄和密度增加，与临床和神经学检查结果进行了比较。在15只犬中发现L7背侧脱位1至8毫米。伸展位在显示该结果方面比屈曲位更成功。所有其他病理变化在腰骶部脊椎滑脱患者中单独或合并出现。136只犬没有L7背侧脱位的迹象，但有所有其他所述变化。所有检测到的变化都必须解释为腰骶部不稳定以及由此导致的慢性和退行性病理过程。在普通X线片上未发现L7/S1脊椎滑脱与马尾神经受压之间存在明确的相关性。
