A variety of techniques were used to study the morbid anatomy of 19 spines demonstrating degenerative spondylolisthesis in order to define the precise changes which produce this lesion and its radiographic appearance. An association between this affliction and vascular disease is suggested. The studies indicate that the listhesis is basically a persistent rotary deformity and not a simple forward displacement. Furthermore, there is no construction of the neural canal at the site of the listhesis. These findings suggest that the myelographic defect and symptomatology arise from traction applied to the nerve root by the medially displaced pedicle.
采用多种技术研究了19例显示退行性椎体滑脱的脊柱病理解剖，以明确产生该病变及其影像学表现的确切变化。提示了这种疾病与血管疾病之间的关联。研究表明，椎体滑脱本质上是一种持续性旋转畸形，而非单纯的向前移位。此外，在椎体滑脱部位不存在神经管狭窄。这些发现提示，脊髓造影缺损和症状是由向内侧移位的椎弓根对神经根施加的牵引所致。
