Analysis method for optimizing number and position of screws used in long bone fracture fixation surgery

An analysis method for optimizing number and position of screws used in a long bone fracture fixation surgery, comprising:

• performing a computed tomography (CT) scan on a surgical patient to obtain at least one medical image and establishing a long bone 3D model based on the medical image;
• performing an X-ray scan on the surgical patient to obtain at least one X-ray image and analyzing the X-ray image to obtain a long bone fracture condition and a bone quality condition;
• selecting a bone plate 3D model from a model database;
• importing the bone plate 3D model into the long bone 3D model, and setting an initial fixation position of the bone plate 3D model;
• instructing a first artificial intelligence to comprehensively analyze the long bone 3D model, the initial fixation position of the bone plate 3D model, the long bone fracture condition, and the bone quality condition, and automatically selecting a plurality of alternative solutions in the model database;
• analyzing a stress distribution of each of the alternative solutions by a computer-aided analysis system, and obtaining a first preferred solution after simulating analysis, wherein the first preferred solution comprises a number of the screws and a locking position of the screws.
