Orthopedia vs St.Gall Algorithm

Essential orthodontic skills, knowledge and guidance for the training orthodontist. The Orthopedia app provides a digital logbook with personalised insights, evidence-based guidance and features simple-to-use tools including an IOTN, IOFTN and ICON calculator. The Orthopedia app has been designed to provide qualified orthodontists and dental professionals with evidence-based advice and guidance. Medical terminology is introduced without detailed explanations, which may be misunderstood by non-healthcare professionals. It is not designed for the general public and therefore should not be used by the general public. It is always important to seek advice from a qualified proffesional in addition to using this app and before making any medical decisions.

This app is intended exclusively for educational and training purposes. It is not a medical device and must not be used for clinical decision-making, patient assessment, or treatment planning under any circumstances. It does not constitute medical advice and is not intended for use with real patients. Explore the St. Gall treatment algorithm for proximal humerus fractures (PHF) as published by Spross et al. (J Bone Joint Surg. 103-A: 2021). This app visualizes the algorithm, letting you trace its decision pathways and understand the logic behind it. The app also includes the functional outcome model from Jacxsens et al. (J Shoulder Elbow Surg. 2025) and lets you practise measuring DTI, GTI, NSA and CSA on X-ray images to understand how these radiographic indices are defined and applied in the literature.
