| Summary: | Background: Levatorani muscle and pelvic connective tissues provide primary support to the pelvic organs.
Women are predisposed to pelvic organ prolapse due to the weakness of pelvic floor muscles and ligament
laxity, which is mostly associated with aging and an increase in intra-abdominal pressure that affects the
biomechanical properties of the pelvic tissues. Hence, this study aims to find the correlation between the spinal
and pelvis disposition among postmenopausal women with and without utero-vaginal prolapse.
Methods: Postmenopausal women who met inclusion and exclusion criteria were randomly selected from
Saveetha medical college and hospital inpatient and outpatient departments. Following assessment, the
postmenopausal women with prolapse were assigned to Group A and without prolapse to Group B. The
participants' angle of lumbar lordosis and pelvic inlet angle calculated in reference to lateral lumbosacral spine
x-rays by a radiologist who was blinded for the study. The data were analyzed statistically using the MannWhitney test and Spearman’s correlation test.
Results: There is a significant reduction in the lumbar lordotic angle and an increase in pelvic inlet angle in
Group A (with prolapse) compared with Group B (without prolapse). Hence, there is an inversely proportional
correlation between the lumbar lordosis and pelvic inlet angle.
Conclusion: The changes in lumbar lordosis angle and pelvic inlet orientation may cause pelvic floor muscle
weakness, which indirectly contributes to utero-vaginal prolapse. This study certainly emphasizes the
importance of postural analysis and corrective pelvic floor therapy regimens for women with utero-vaginal
prolapse.
