“…For patients with balanced pelvis and spine, either fusion in situ or fusion with reduction and xation can be used. Our results show that the inter-and intra-observer agreement K value of SDSG classi cation are 0.704 and 0.861, respectively, which are slightly higher than that of the previous agreement studies by Mac-Thiong et al [21] (0.65, 0.74) and Bao et al [22] (0.648, 0.830), indicating relatively better consistency strength. In these studies, the case scope of assessment of SDSG classi cation covered dysplastic, degenerative and isthmic spondylolisthesis.…”

Background: Lumbar degenerative spondylolisthesis (DS) has been a common disease that make increasing patients suffer from different degrees of low back pain and radicular symptoms. SDSG and CARDS systems are commonly used to classify the disease, and help to make a more detailed treatment plan. The objective of this study is to evaluate the reliability and reproducibility of SDSG and CARDS classifications, and to explore their clinical application value.Methods/Design: All 117 patients with L5/S1 lumbar DS were enrolled. 5 spine surgeons who have certain clinical experience were selected. They determined the classification according to S SDSG and CARDS systems, we used kappa (K) value to check the coefficient consistency for multi-factor and assess the inter- and intra-observer agreement. After 12 weeks, we repeated the analysis.Results: The inter-observer reliability and intra-observer reproducibility of SDSG system were substantial with K values of 0.704 and 0.861, while those of CARDS system were substantial with values of 0.620 and 0.878.Conclusion: SDSG system has better inter-observer reliability in comparison with CARDS system, and though CARDS system is more intuitive and simpler, it is more likely to produce deviations when using it. Since both SDSG and CARDS systems show substantial agreement and have great significance in surgical strategy of L5/S1 lumbar DS, they can be widely used in clinical practice.

“…With great effort, the Spinal Deformity Study Group proposed a new classification of the lumbosacral spondylolisthesis. They divided the L5-S1 spondylolisthesis into six subtypes according to the slip grade, PI, and sagittal balance [11,12].…”

“…Spondylolisthesis is displacement of a vertebral body on the one below and may result from several etiologies, of which the most common are spondylolysis and spondylotic degeneration. 7 – 9 In our patient chronic degenerative spondylolisthesis at L5/S1 had resulted in spontaneous spinal arthrodesis, which may occur to some extent in as many as 20.9% of patients with spondylolisthesis. While the complications of spinal segmental instability with regards to neurological complications and back pain are well described, 10 – 12 the potential for distortion of the pelvic vasculature has not previously been widely recognized.…”

May-Thurner variant secondary to degenerative lumbar spondylolisthesis: a case report

et al. 2017

View full text Add to dashboard Cite

May-Thurner syndrome (MTS) is a rare condition in which patients develop iliofemoral deep venous thrombosis due to an anatomical variant in which the right common iliac artery overlies and compresses the left common iliac vein against the lumbar spine. We report a case of variant MTS, where vascular distortion secondary to spontaneous spinal arthrodesis of degenerative lumbar spondylolisthesis resulted in left common iliac vein compression and iliofemoral deep vein thrombosis. While the common complications of degenerative spondylolisthesis, such as spinal stenosis, are well described; the potential for pelvic vascular distortion secondary to anterior translation of the lumbar spine is not well recognized. The purpose in presenting this case is to describe the mechanism by which this variant of MTS occurs and highlight the need for vigilance for this unusual clinical entity.
