Description
Summary:Metacarpal fractures are one of the most common types of fractures, comprising nearly 20% of emergency room visits. These types of fractures, however, are often neglected and left untreated. The lack of treatment, which usually due to high cost, may lead to deformities and disabilities for the affected patient. This study involved material selection and design of a miniature external fixator that may be easily manufactured, leading to improved accessibility and affordability. The study used Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) multi-criteria decision-making method to screen candidate materials and determine which materials were the most suitable to the desired application. For a metallic fixator, Ti6Al4V was identified to be the best material and for a polymer-based fixator, the polyethylene terephthalate (PET) was found to be the most suitable. A design was also developed to serve as a basis for prototype.
