“…Multiple research works analyzed the correlation of LLA and PI suggesting a significant positive relationship of r = 0.40 to 0.72 (p < 0.001). 4,9,12,27 This showed that as the PI decreases, lumbar lordosis decreases and disc pressure increases and degeneration occurs in the disc leading to low back pain. In this study, we also found a positive significant correlation of r = 0.492 having a pvalue < 0.001 between PI and LLA.…”

Objective: To determine the significance of the correlation between spinopelvic parameters in patients with chronic low back pain. Materials and Methods: 129 patients with chronic low back pain of a minimum of 03 months duration were included in our study from September 2020 to February 2023. Sagittal standing spinopelvic radiographs were done on all patients. Various spinopelvic measurements were done including PI, PT, LLA, SLA L1 – L3, SLA L3 – S1, LSA, SHA, and SIA. Pearson correlation was used to determine the correlation coefficient. Results: The mean age was 36.45 ± 9.54 years. Males were 59 and females 70. Mean and SD of spine pelvic measures were LLA = 57.32 ± 12.45, SLA L1-L3 = 15.31 ± 3.75, SLA L3 – S1 = 42.46 ± 8.34, LSA = 8.94 ± 4.72, SHA = 38.10 ± 7.94, SIA = 52.42 ± 6.84, PT = 11.21 ± 5.83, PI = 48.72 ± 8.90. PI has a significant positive correlation with LLA ( r= 0.492 and p-value < 0.001). Conclusion: PI and LLA are important spinopelvic parameters and have significant correlation with other spinopelvic parameters and derangement of one of them can affect the overall spine sagittal balance resulting in chronic low back pain.

“…In people with spondylolisthesis, changes are observed in the SS, PI and PT angles as the pelvic positions change. It is thought that the increase in SS, PI and PT angles leads to the progression of spondylolisthesis and many spinal problems [24]. People with L5-S1 spondylolisthesis have an increased SS angle, which affects the progression of spondylolisthesis.…”

Objective: In recent studies, the relationship between sacrum morphology and orientation and spondylolisthesis has gained importance. The present study aimed to compare the morphometry of the sacrum between patients with L5-S1 spondylolisthesis and healthy subjects on multidetector computed tomography (MDCT) images. Methods: In this study, abdominopelvic MDCT images of 191 individuals (age range 20-92 years; 101 males and 90 females; 56 patients diagnosed with L5-S1 spondylolisthesis and 135 healthy individuals) were retrospectively evaluated. In this study, the sacrum parameters (Intercornual distance (ICD), sacral hiatus length (LHS), anteroposterior diameter of hiatus at the apex of sacral hiatus(APCWHSA), sacral height (SH), sacral table angle (STA), sacral table index (STI), S1 superior angle (S1A), sacral slope(SS)) evaluated morphometric and morphological in healthy individuals and patients with L5-S1 spondylolisthesis. Kolmogorov–Smirnov test was used to test the normality, which is one of the parametric test assumptions, of the data. Results: Age parameter was found statistically significant higher in the patient group (p<0.001). STA, S1A, SH, LHS and APCWHSA measurements were found to be significantly higher in the healthy group. (p<0.001, p<0.001, p=.008, p=.005, and p=.002, respectively). STI and ICD were found to be significantly higher in women in the healthy group (p=.031, p=.010), while SH parameter was found statistically significant higher in men in the healthy group (p=.007). SS was found statistically significant lower in the healthy group (p<0.001). S1A, L5-S1 spondylolisthesis was found statistically significant higher than Grade 1, Grade 2 according to the degree of slippage (p=.045). Conclusion: The results of this study showed that sacral morphology is important in the development or at least progression of spondylolisthesis.

“…That is, a large PI is accompanied by a small STA, and a small PI was associated with a large STA [ 11 ]. Previous investigations have demonstrated that patients with large STA were more susceptible to lumbar disc herniation, whereas patients with small STA were prone to lumbar degenerative spondylolisthesis [ 20 , 21 ]. Ergun had also reported that the degree and risk of intervertebral disc degeneration and herniation increases in parallel to the increase of STA in the case of the same PI [ 22 ].…”

Background The sacrum plays an important role in sagittal balance of the spine, whereas the exact association between sacral parameters, specifically the sacral table angle (STA) and spinopelvic parameters has been only scarcely assessed. It aims to investigate the correlations between the sacral parameters and spinopelvic sagittal alignment parameters in healthy adults. Methods A cohort of 142 Northern Chinese healthy adults between 18 and 45 years old were recruited between April 2019 and March 2021. Full-spine standing X-ray films were performed for every volunteer. The sacral parameters were measured: sacral table angle (STA), sacral inclination (SI) and sacral slope (SS). The spinopelvic sagittal alignment parameters included: pelvic incidence (PI), pelvic tilt (PT), lumbar lordosis (LL), thoracic kyphosis and the apex of lumbar lordosis (LLA). The correlations analysis, as well as the linear regression analysis, were performed between STA, SI and the spinopelvic parameters. Results An equation ‘STA = SI + 90 − SS’ was revealed to represent the interrelationships between STA, SI and SS. STA was statistically correlated with PI (rs = − 0.693), PT (rs = − 0.342), SS (rs = − 0.530), LL (rs = 0.454), and LLA (rs = 0.438). SI correlated with STA (rs = 0.329), PT (rs = − 0.562), SS (rs = − 0.612) and LL (rs = 0.476). Simple linear regression analysis also verified the correlation between STA and PI (y = − 1.047x + 149.4), SS (y = − 0.631x + 96.9), LL (y = 0.660x − 117.7), LLA (y = 0.032x + 0.535), and SI (y = 0.359x + 8.23). Conclusion The equation ‘STA = SI + 90 − SS’ indicates the exact geometric relationship between STA, SI and SS. The sacral parameters, both STA and SI, correlate to the spinopelvic sagittal alignment parameters in healthy adults. The linear regression analysis results also give predictive models for spinopelvic sagittal alignment parameters based on the invariant parameter STA, which are helpful for surgeons in designing an ideal therapeutic plan.
