Background: Pelvic incidence (PI) and pelvic parameters (PP) regulate the sagittal alignment of the spine and the pelvis in normal populations. Correlation of PI even more so than PP with lumbar spondylolisthesis (LS) would be useful for surgical planning.
Methods: This study included 45 patients randomly selected with LS. They were divided into two groups; Group S had LS and Group C had low back pain due to other causes. All patients received lateral standing radiographs of the spine and pelvis. Based on these films, we measured the sacral slope, pelvic tilt, PI, and lumbar lordosis (LL).
Results: There were significant correlations between the PI and the sacral slope, pelvic tilt, and LL in Group S (P
Conclusion: Changes in spinopelvic parameters reflecting pelvic compensatory mechanisms differ depending on the extent of PI in patients with LS. In short, higher PI values correlated with more significant degrees of degenerative LS in Group S population.

The previous reports demonstrate that the pelvic incidence (PI) determines the sagittal spinal and pelvic alignment in normal populations. Understanding sagittal balance, including spinal alignment and the pelvic orientation, is critical for spine surgeons. Here, we evaluated the role of PI as it related to lumbar spondylolisthesis (LS) in patients under consideration for lumbar surgery.
We randomly selected 45 patients with LS. Patients were all above 18 years of age and had LS. Those who had prior surgery were excluded from the study. Patients were divided into two groups; Group S (45 patients) had LS, while Group C (45 patients) had low back ache due to other causes. Patients were assessed utilizing lateral standing radiographs to determine sacral slope, pelvic tilt lumbar lordosis (LL), and the PI.
Data were analyzed using the Statistical Package for the Social Sciences version 20.0 software. For qualitative data, various rates, ratios, and percentage (%) were calculated. For quantitative data, mean, SD, median, etc., were calculated. A two-tailed test with P < 0.05 was considered as statistically significant.
Wang et al. identified the influence of PI on spinopelvic parameters in patients with degenerative lumbar scoliosis (DLS).[
Changes in spinopelvic parameters reflect pelvic compensatory mechanisms that differ depending on the extent of PI in patients with LS.
