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.
