Objective: Given high prevalence of pelvic organ prolapse in female, and necessity of effect assessment of it's risk factors in various societies, this study was aimed to investigate the correlation of thoracic and lumbar spinal curvature as well as pelvic tilt changes with pelvic organ prolapse.
Materials & Methods: In this cross-sectional and case-control study, fifteen females with pelvic organ prolapse, on the basis of inclusion criteria were selected by simple and convenient sampling from Imam Khomeini and Akbar abadi hospitals patients as case group. Also, fifteen females with zero or first degree of prolapse were selected by matching with cases as control group. Prolapse condition of both groups participants was assessed by pelvic organ prolapse qualification (POP-Q) system and spinal curvature of thoracic and lumbar as well as pelvic tilt were assessed by flexicurve ruler and pelvic inclinometer, respectively. Data were analyzed by Kolmogroff-Smirnoff, Independent T and Multiple Logistic Regression tests.
Results: There was no significant difference between two groups in kyphosis (P=0.26), lordosis (P=0.52) and pelvic tilt (P=0.41).
Conclusion: Although the results of study do not show significant correlation between kyphosis, lordosis and pelvic tilt with pelvic organ prolapse occurrence but similar direction of changes in the variables with our hypothesis and other studies preserve the likelihood of relationship between the increasing of kyphosis and decreasing of lordosis in pelvic organ prolapse in a large statistic society.
