The clinical and radiological incidence of lumbosacral (LS) disease was studied on 57 German Shepherd dogs (GSDs) used in active service. The study included a clinical history, a neurological examination, and plain radiographs of the caudal lumbar vertebrae. The neurological examinations revealed lower back pain and/or neural deficits in 21 dogs, of which 14 had a history of pain or pelvic gait abnormalities. Radiographic findings were spondylosis at L7-S1, degeneration of L7-S1 disc, LS malalignment, transitional LS vertebrae and/or primary spinal canal stenosis in 15 dogs with neurological abnormalities and/or back pain and in 18 dogs with no clinical signs. No correlation between the neurological and the radiographic findings were found. This study demonstrates that even prominent radiographic LS abnormalities are of minimal value in the evaluation of LS disease in the GSD.
对57只现役德国牧羊犬（GSD）的腰骶部（LS）疾病的临床和放射学发病率进行了研究。该研究包括临床病史、神经学检查以及腰椎尾段的X线平片。神经学检查发现21只狗存在下背部疼痛和/或神经功能缺损，其中14只狗有疼痛史或骨盆步态异常。在15只伴有神经功能异常和/或背痛的狗以及18只无临床症状的狗中，X线检查结果显示L7-S1椎体骨质增生、L7-S1椎间盘退变、腰骶部排列不齐、过渡性腰骶椎和/或原发性椎管狭窄。未发现神经学检查结果与X线检查结果之间存在相关性。这项研究表明，即使是明显的腰骶部X线异常在评估德国牧羊犬的腰骶部疾病时价值也很小。
