Significance of Correlation Between Spinopelvic Parameters in Patients of Chronic Low Back Pain

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.
