Abstract:
Objectives
An alternative to both the time-consuming traditional and the expensive three-dimensional (3D) methods for splint design is to use two-dimensional (2D) images. The present study utilized image processing to achieve an automatic and practical method of anthropometry measurement to design and build a personalized and remote cock-up splint. This method is applicable for patients unable to personally attend clinic appointments.
Methods
The defined landmarks of the cock-up splint of 100 adult participants were measured manually. Each individual had a 2D image taken of their upper limb using a customized imaging device. The 2D image portions that corresponded to the manual measurements were then identified, and their sizes were retrieved in pixels using MATLAB software. To find equations between manual 3D measurements and 2D image processing ones, multiple linear regression analysis was performed on landmark variables.
Results
We were able to determine equations to estimate manual dimensions based on 2D image data. In the men’s group, we could predict the third finger length, forearm circumference at three levels, and the largest forearm circumference. In the women’s group, in addition to variables predicted for men, hand circumference at the distal palmar crease and first web levels, as well as arm circumference, could be predicted using the identified equations.
Conclusion
Based on the findings, 2D image processing could be an appropriate method for designing personalized cock-up splints. Level of evidence: III
