摘要
Study Design. A radiographic study of the sagittal sacral deformity in spondylolisthesis. Objectives. To characterize and classify the pathoanatomy bf Sagittal sacral deformation in spondylolisthesis. Summary of Background Data. Spondylolisthesis has been extensively described and reviewed in the literature. Deformity of the entire sacrum in spondylolisthesis potentially could affect the natural history, treatment options; and outcome. The sagittal contour of the entire human sacrum has never been quantitatively studied in spondylolisthesis. Methods. A literature search was performed and data was gathered retrospectively on patients with spondylolisthesis at the authors' institution. Cases of degenerative spondylolisthesis were excluded. Specifically those patients with F5-S1 spondylolisthesis were studied. The authors studied standing lateral radiographs and performed statistical analysis to understand morphologic relations. Results. A broad range of global sacral kyphosis (37-188 degrees) exists in spondylolisthesis. Increasing sacral kyphosis is significantly associated with increasing percent slip, sacral horizontal angle, Neuman's classification, lumbar lordosis, and lumbar index. A simple classification of the spectrum of sacral deformity in the sagittal plane is presented. Conclusion. The entire sacrum in spondylolisthesis can develop a significant kyphotic deformity in the sagittal plane, and this is associated with other abnormalities found in the lumbosacral spine. Sacral deformity is a significant factor in the assessment of the sagittal contour of the patient with L5-S1 spondylolisthesis.
