Summary
Traditional plaster casts cause discomfort and hygiene issues. Advanced 3D scanning technologies, particularly photogrammetry, offer a radiation-free, efficient method for creating custom orthoses, improving patient care and rehabilitation.
Area of Science:
- Biomedical Engineering
- Orthopedics
- Medical Imaging
Background:
- Traditional plaster casts for limb immobilization present significant patient discomfort, including itching, sweating, and hygiene challenges.
- Prolonged use of plaster casts can lead to joint and ligament lesions, complicating recovery.
- Manual fabrication of orthoses is time-consuming and prone to errors, hindering efficient patient care.
Purpose of the Study:
- To explore advanced 3D scanning technologies as alternatives to traditional methods for orthoses manufacturing.
- To evaluate the suitability of non-ionizing radiation 3D scanners for digitizing the human body for custom orthosis production.
- To highlight the potential of 3D scanning in improving the efficiency and patient experience in orthotic rehabilitation.
Main Methods:
- Review and description of various non-ionizing radiation 3D scanning technologies applicable to human body digitization.
- Analysis of photogrammetry as a prominent and suitable 3D scanning technique for anatomical data acquisition.
- Discussion on the integration of 3D scanning data into the custom orthoses manufacturing workflow.
Main Results:
- Photogrammetry is identified as the most utilized and appropriate 3D scanning method for capturing human body geometry.
- 3D scanning significantly reduces the time required for data acquisition compared to manual methods.
- The adoption of 3D scanning technology offers a radiation-free alternative to medical imaging for orthoses fabrication.
Conclusions:
- 3D scanning technologies, especially photogrammetry, provide a superior alternative to traditional plaster immobilization and manual orthosis production.
- The implementation of 3D scanning in clinical settings can enhance rehabilitation processes and patient self-care.
- Continued technological evolution promises further reductions in scanning time and increased clinical accessibility of 3D scanning for custom orthoses.
