Zusammenfassung:The invention provides an orthopedic postoperative screw looseness prediction method and system based on skeleton imaging, and relates to the technical field of intelligent medical systems, and the method comprises the steps: obtaining a spine image set of a target patient; constructing a target spine three-dimensional model for the target patient based on the spine image set of the target patient and a preset screw three-dimensional assembly of the corresponding screw; extracting a model module with a preset size at the periphery of the screw from the target spine three-dimensional model so as to determine a corresponding bone tissue module at the periphery of the screw; generating a corresponding target map structure according to the bone tissue module around the screw; and inputting the target graph structure into a preset screw looseness prediction model to determine a screw looseness prediction result, the screw looseness prediction model adopting a graph neural network. Therefore, a screw looseness pred
