Potentialities and limitations of a database constructing three-dimensional virtual bone models

Area of Science:

• Anatomy
• Medical Imaging
• Biomechanical Engineering

Background:

• Current 3D bone reconstructions in clinical practice have limited utility for research and training.
• A database of 3D virtual bone models from computed tomography (CT) scans is being developed.
• This initiative aims to address the limitations of existing clinical 3D bone data.

Purpose of the Study:

• To create a comprehensive database of human 3D virtual bone models.
• To provide a sustainable resource for morphological and biomechanical studies.
• To enhance medical education and training through virtual models.

Main Methods:

• Computed tomography (CT) datasets were processed using Amira software.
• Bone structures were isolated using semi-automatic labeling techniques.
• Precise 3D bone models were generated in Standard Triangulated Language (STL) format.

Main Results:

• The database currently contains 131 pelvises and 120 femurs, with ongoing expansion.
• 3D morphometric analyses of the posterior ring and acetabulum have been successfully performed.
• 80 students (96%) rated instruction with virtual 3D bone models as "good" or "very good".

Conclusions:

• The growing database offers a sustainable alternative to cadaveric dissection for practical investigations.
• The virtual 3D bone models serve as an effective platform for medical education and training.
• Student feedback indicates a strong desire for expanded use of virtual bone models in learning.
