Finite element-based orthopedic implant loosening prediction method

The invention provides an orthopedic implant loosening prediction method based on a finite element, and relates to the technical field of intelligent medical systems, and the method comprises the steps: obtaining a target patient spine image set and target patient clinical data; extracting an image feature attribute set from the spine image set of the target patient; inputting the image feature attribute set and the screw material type into a preset finite element analysis FEA generation model to determine corresponding simulated FEA data; the FEA generation model adopts a generative adversarial network; fEA processing is carried out on the spine image set of the target patient to obtain current real FEA data; the simulated FEA data, the current real FEA data and the clinical data of the target patient are input into a preset screw looseness prediction model to determine a screw looseness prediction result, and the screw looseness prediction model adopts a deep learning model. Therefore, the FEA data analysis
