Abnormal spinal curvature is linked to a higher stage of pelvic organ prolapse (POP). This finding highlights the importance of assessing spinal health in POP patients.
Area of Science:
- Gynecology
- Orthopedics
- Public Health
Background:
- Pelvic organ prolapse (POP) is a common condition affecting women's health.
- Spinal curvature abnormalities may influence pelvic floor support structures.
Purpose of the Study:
- To investigate the association between spinal curvature changes and the stage of pelvic organ prolapse.
- To identify potential risk factors for POP development.
Main Methods:
- A cross-sectional study involving 200 women (100 cases with spinal abnormalities, 100 controls).
- Pelvic organ prolapse quantitation (POP-Q) staging system used for prolapse assessment.
- Flexi-curve malleable rod used for measuring thoracic and lumbar spine dimensions.
Main Results:
- Patients with abnormal spinal curvature (cases) exhibited a significantly higher stage of pelvic organ prolapse compared to controls (p=0.035).
- Grade II prolapse was most prevalent (56%) among cases, followed by grade III (32%), grade I (5%), and grade IV (7%).
Conclusions:
- Abnormalities in spinal curvature are associated with increased severity of pelvic organ prolapse.
- Spinal health should be considered when evaluating risk factors for POP.
- Further research is warranted to elucidate the biomechanical relationship between spinal and pelvic structures.

Vertebral Column: Regions and Curvature
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form the...
