Mimicking a Model: A Novel Approach to Pelvis and Perineum Dissection

Abstract

Pelvic dissections are difficult for students to visualize and complete given the standard dissection approach and limited time provided in standard anatomy curricula at U.S. medical schools. The purpose of this project is to propose a novel approach to dissecting the pelvis with aims of increasing student understanding of pelvic anatomy. The proposed novel technique allows for ease of viewing by making the donor more mobile and more model‐like, like what is seen with common anatomical models used at medical schools.The technique begins with transverse sectioning of the body into, an upper, mid, and lower section with the mid‐section containing the pelvic region. This section allows the dissector to utilize the pelvic bowl in a standing position, show cross‐sectional anatomy of the thigh muscles, and provide focus on three different dissection pathways. The pathways created include, neurovascular, organ, and muscle specific.On a preliminary dissection, this method provided ease at dissecting this region, a structurally similar view to live bodies and models, and additional pathways for learning. This dissection was done by a first‐year medical student six months following typical anatomical dissection. The technique is beginning to redefine in situ study of the pelvis and perineum by providing an alternative, more focused way to utilize donors for this region. Models tend to provide the “perfect” anatomy, which can be useful in understanding the typical relationships, however, it is important for students to understand this region and the relationships found with each structure to help better prepare them for future patients.Future studies to enhance this technique will determine how the pathways can be better utilized. In having students perform this technique alongside the typical techniques, a comparison can be made with a larger population. By having subjective feedback, it can show how students interacted with the dissection, as well as how it was utilized throughout this region of study.
