Background: Medical smartphone applications have rendered positive results in daily practice and also serve as potentially valuable educational tools. In orthopedics, radiograph analysis and angle measurements comprise an essential mechanism in the diagnosis, treatment, planning, and evaluation of the results in orthopedic surgery. Purpose: Thus, the present study aimed to evaluate an application for mobile devices for orthopedic doctors and orthopedic residents. The application proposes the analysis and interpretation of radiographic imaging examinations through assessments and angle measurements. In this survey, we analyzed the parameter usability and usefulness of a mobile application for the iOS system, in addition to conducting its validation. Patients and Methods: The application was tested by 26 volunteers: 13 orthopedists and 13 orthopedic residents. Results: After applying the System Utility Score (SUS) questionnaire, which assesses the usability of an application, a score of 84.5 was obtained, a value that represents an A+ rating on the Sauro and Lewis scale. There was no statistically significant difference when comparing the SUS between the orthopedic residents and orthopedists. According to the usefulness perception analysis, 90% of the residents responded positively to the questions, while among orthopedists, the percentage was 75%, denoting a statistically significant difference (p = 0.002). Subsequently, the application underwent validation to assess whether the calculated angle measurements were reliable when compared with those obtained using the goniometer. No significant differences were observed when comparing the angles measured by the two evaluated methods. Conclusion/Clinical Relevance: In conclusion, the developed application can reliably contribute to the measurement of angles in radiographs, assisting in therapeutic decision-making, and may be used as an instrument to promote the teaching and learning processes in orthopedics.
