Summer 2020 Undergrad Project - Modeling the Pelvic Bone and Vaginal Canal

Feder, Arielle D.; Rajasekharan, Divya; Louwagie, Erin Marie; Myers, Kristin M.

This work is a summation of Divya Rajasekharan and Arielle Feder’s 2020 summer project of parametrically modeling the pelvic bone and vaginal canal in the Myers Soft Tissue Lab at Columbia University.

In order to simulate the mechanics of birth, accurate models of reproductive anatomy must be acquired, including the pelvic bone and vaginal canal. The vaginal canal modeling method is based off of measurements from existing literature, capturing the vaginal axis and transverse width. Though currently employing patient averages, we have built the model such that patient-specific measurements of the vaginal canal can be used in the future. The pelvic bone modeling method introduces simplifications that capture the structures relevant to fetal head decent, while also capturing patient-specific pelvic inlet shape. Thus, the pelvic bone is reduced to a ring that can capture most pelvic inlet shapes and solid body to represent the sacrum. In the future, these structures will be implemented into a finite element analysis simulation of birth and their effect on the mechanics of delivery explored.
