Development and validation of therapeutic resources for the rehabilitation of fractures related to the upper limbs through the use of 3D printing

Abstract

Introduction: The upper limbs are structures of the appendicular skeleton attached to the axial skeleton. However, when this segment goes through a trauma event, different deficits related to the compromise of its structures can be installed. Objective: The objective of this study is to present the possibilities of developing and creating rehabilitation resources for fractures related to the upper limbs in adult patients based on three-dimensional printing. Methodology: Quantitative, analytical, descriptive and cross-sectional study, without intervention. Development of resources using Computer Aided Design (CAD) and slicing software. Validation was carried out using a 5-point Likert scale applied in the form of a questionnaire with 10 expert judges. Results: 3 therapeutics resources were created and, to corroborate the application of the questionnaire, a cost study was constructed for these, with a final value of R$ 63.05. By collecting the judges' responses and analyzing their responses to the scale, the devices can be validated with an overall average of 77.5%. Discussion: With this, it is stated that equipment capable of acting in the rehabilitation of the target audience was produced, presenting characteristics such as reduced weight, low cost, satisfactory design and aesthetics in addition to its employability in the rehabilitation clinic. Conclusion: As it unfolded, it was possible to validate and create satisfactory cost-benefit benchmarks for personal improvement and national and international scientific research, contributing as a subsidy for investigations of the same nature that, perhaps, will be idealized in the future.
