The Scoliosis Assessment Aid (SAA), a free mobile application available on Google Play, represents an innovative platform for supporting the evaluation and management of scoliosis in accordance with the 2011 and 2021 guidelines of the International Scientific Society on Scoliosis Orthopaedic and Rehabilitation Treatment (SOSORT). This summary provides a concise analysis of the app’s functionalities, scientific foundations, and potential impact based on a study involving 450 adolescent cases (aged 10–18 years) in 15 international centers (2023–2025). The app offers a user-friendly interface that allows input of data such as age, sex, and Cobb angle, generating immediate treatment recommendations (periodic monitoring for 10°–25° angles or bracing for >25°). Clinical trials have demonstrated high concordance with specialist evaluations (κ=0.89, p<0.001), reducing clinical decision-making time by 15%. SAA incorporates validated diagnostic tools, including Cobb angle measurement and the Adams Forward Bend Test, supported by advanced statistical analyses (Bootstrap, Shapiro-Wilk). Despite its effectiveness in standardizing assessments and enhancing care efficiency, the app relies on manual input, which can lead to measurement errors of 5-8%, and is currently limited to English. Future developments include integrating artificial intelligence for curve progression prediction, multilingual support, and interactive user training. The SAA highlights the role of technology in improving diagnostic precision and empowering patients, particularly in resource-constrained settings, positioning it as a benchmark for innovation in spinal deformity management.
