Abstract:Objective To analyze the association between hip and pelvic stability and non-specific low back pain (NSLBP)by comparing the coronal and sagittal imaging parameters.Methods We conducted a case-control study.The digital x-ray system was used to collect the pelvic positive and lateral image parameters from the low back pain group (n=33) and the healthy group (n=66).The imaging parameters between the two groups were compared for statistically significant differences,and the relationship between each parameter and low back pain was analyzed.The two cohorts were compared in parameters including the Obturator foramen size (OFS),Pelvic rotation angle (PRA),sacral slope (SS),Pelvic incidence angle (PI),and lumbosacral angle (LSA).OFS and PRA are the indicators of the balance of the vertical axis and sagittal axis of the bilateral hip bones,respectively.SS associates with the balance of pelvic coronal axis.Results The comparisons in parameters OFS,PRA,and SS showed significant differences between the groups,and they all had correlation with NSLBP to different extent.Except for the significant correlation between OFS and SS,there was no significant correlation between other parameters.Simultaneous abnormalities in OFS,PRA,and SS were associate with increased incidence of low back pain.OFS had certain value for the diagnosis of NSLBP.Conclusion Hip symmetry imbalance can cause pelvic instability.There was a significant correlation between hip symmetry imbalance and NSLBP.
