Area of Science:

Biomechanics
Computational modeling
Obstetrics

Background:

Childbirth is a biomechanical process involving uterine forces and pelvic resistance.
Existing models often focus on either uterine or pelvic structures, not both.
A comprehensive model is needed to understand the interplay between these structures during labor.

Purpose of the Study:

To develop and validate a finite element method (FEM) model simulating the entire childbirth process.
To integrate uterine biomechanics and pelvic resistance within a single computational framework.
To provide a tool for investigating labor pathomechanics and related complications.

Main Methods:

Developed an FEM model in LS-DYNA incorporating uterus, pelvic floor muscles, and bony pelvis.
Modeled uterine contraction using contractile fiber elements (Hill material model).
Simulated three cycles of uterine contraction and validated model outputs against labor data.

Main Results:

Successfully simulated fetal delivery dynamics, including stress distribution and pelvic floor muscle response.
Validated model outputs against key labor parameters like duration and fetal movement.
Demonstrated the model's capability to analyze biomechanical forces during childbirth.

Conclusions:

The developed FEM model provides a comprehensive simulation of childbirth.
This integrated approach allows for the investigation of labor pathomechanics.
The model has potential applications in understanding pelvic floor disorders and brachial plexus injury.
