“…[9][10][11][12][13][14] Five studies reported a correlation between PI and slip grade, [9][10][11][12][13] all finding that PI was significantly higher in spondylolisthesis patients compared to controls (e.g. 76° vs. 48.2-53.2°, respectively).…”

“…S1 remodeling by dysplastic L5 and loss of L4 and S1 articulation makes border identification dificult. Vialle et al noted that patients with low SS had a more easily reduceable spondylolisthesis 14 and that SS, PT, and LL measurements in HGS were compensatory for high PI. 13 Schuller et al found that BMI was significantly higher in a spondylolisthesis group compared to control and suggested that increased PT in HGS patients most likely results from a compensatory posterior pelvic tilt.…”

Surgical Treatment Strategies for High-Grade Spondylolisthesis: A Systematic Review

et al. 2015

View full text Add to dashboard Cite

Background HGS is a severe deformity most commonly affecting L5-S1 vertebral segment. Treatment available for HGS includes a range of different surgical options: full or partial reduction of translation and/or abnormal alignment and in situ fusion with or without decompression. Various instrumented or non-instrumented constructs are available, and surgical approach varies from anterior/posterior to combined depending on surgeon preference and experience. The aim of this systematic review was to review the literature on lumbosacral high-grade spondylolisthesis (HGS), identify patients at risk for progression to higher-grade slip and evaluate various surgical strategies to report on complications and radiographic and clinical outcomes.

“…We, therefore, recommend the use of the posterior border of S1 as the landmark to measure Dubousset's LSA. With progression of slippage, the inferior endplate of L5 tends to become dysplastic [19,28] and the L5 vertebral body may adopt a trapezoidal shape [31]. Moreover, remodeling of the S1 endplate can occur and is referred to as sacral doming or rounding [20,31] (Fig.…”

Assessment of lumbosacral kyphosis in spondylolisthesis: a computer-assisted reliability study of six measurement techniques

et al. 2008

Although recognized as an important aspect in the management of spondylolisthesis, there is no consensus on the most reliable and optimal measure of lumbosacral kyphosis (LSK). Using a custom computer software, four raters evaluated 60 standing lateral radiographs of the lumbosacral spine during two sessions at a 1-week interval. The sample size consisted of 20 normal, 20 low and 20 high grade spondylolisthetic subjects. Six parameters were included for analysis: Boxall's slip angle, Dubousset's lumbosacral angle (LSA), the Spinal Deformity Study Group's (SDSG) LSA, dysplastic SDSG LSA, sagittal rotation (SR), kyphotic Cobb angle (k-Cobb). Intra-and inter-rater reliability for all parameters was assessed using intra-class correlation coefficients (ICC). Correlations between parameters and slip percentage were evaluated with Pearson coefficients. The intra-rater ICC's for all the parameters ranged between 0.81 and 0.97 and the interrater ICC's were between 0.74 and 0.98. All parameters except sagittal rotation showed a medium to large correlation with slip percentage. Dubousset's LSA and the k-Cobb showed the largest correlations (r = -0.78 and r = -0.50, respectively). SR was associated with the weakest correlation (r = -0.10). All other parameters had medium correlations with percent slip (r = 0.31-0.43). All measurement techniques provided excellent inter-and intra-rater reliability. Dubousset's LSA showed the strongest correlation with slip grade. This parameter can be used in the clinical setting with PACS software capabilities to assess LSK. A computer-assisted technique is recommended in order to increase the reliability of the measurement of LSK in spondylolisthesis.

“…[1][2][3][4][5][6][7][8][9][10][11][12][13] On the opposite, measurement techniques 5,6,14 that only express the relative position or shape of the dome have no clear association with slip grade. Second, results have shown that the SDSG index is in agreement with the clinical knowledge and perspectives of the 5 spine surgeons involved in this study.…”
