Open-Access 3D Bone Shape Databases in Orthopedics: An Unmet Need?

Objective: 3D bone shapes play a critical role in preclinical and clinical orthopedic applications. This study aimed to identify and evaluate 10 most relevant existing online CT databases to see if they meet requirements of biomedical experts. Method: We performed a systematic search to identify relevant online CT databases for lower extremities. Additionally, a workshop with n=40 biomedical experts was held to gather insights on the benefits, challenges, and users for an online 3D bone shape database. This information was used to establish criteria to evaluate the identified databases. Results: We found that currently available online databases inadequately address experts’ needs, particularly regarding inclusion of different shape formats, such as 3D meshes and CAD models, and inclusion of mechanical properties of bones. Conclusion: These findings highlight a significant gap between databases’ offerings and users’ needs, underscoring the need for more comprehensive, accessible resources and advanced tools to support the field's progression.
