A Reliable Low-Cost Three-Dimensional (3D)-Printed Brachial Plexus Model for Enhanced Anatomical Learning

Area of Science:

• Anatomy
• Medical Education
• 3D Printing Technology

Background:

• The brachial plexus's complex 3D structure challenges anatomical learning.
• Traditional 2D resources and expensive commercial models limit accessibility for many institutions.
• Effective spatial visualization is crucial for understanding this neurological network.

Purpose of the Study:

• To develop a practical and cost-effective 3D-printed brachial plexus model.
• To provide an accessible learning tool for students and educators.
• To evaluate the model's effectiveness in anatomy education.

Main Methods:

• Direct 3D scanning of cadaveric brachial plexus structures.
• Creation of an affordable 3D-printed anatomical model.
• Pilot study involving physician assistant students using anonymous surveys.

Main Results:

• The 3D-printed model accurately captures key anatomical details of the brachial plexus.
• Pilot study feedback from students indicated the model's potential to enhance learning.
• The model offers a low-cost alternative to existing educational tools.

Conclusions:

• The 3D-printed brachial plexus model is a viable, cost-effective solution for anatomy education.
• This accessible tool can improve spatial understanding and bridge educational gaps at low-resource universities.
• The model is available for academic use to facilitate further evaluation and adoption.
