Abstract:Digital medicine is an emerging frontier science that combines digital medical diagnosis, treatment and detection technolo-gy with the help of information technology and modern medical research and practice in recent years. Digital medicine includes 3D modelreconstruction, surgical navigation systems, 3D printing technology, personalized surgical guides and surgical robots. Three dimensionalprinting, also known as 3D printing, is a rapid prototyping technology that constructs objects by printing them layer by layer, based on digi-tal model files and using adhesive materials. From customized foot and ankle orthotics to customized osteotomy guides and screw guides, 3Dprinting technology has been gradually applied in the field of foot and ankle surgery. From preoperative planning and education, medical ed-ucation, and then to the application of clinical medical practice, the advantages of 3D printing technology involve various aspects. Withmore detailed preoperative planning, more streamlined surgical procedures, and more efficient doctor-patient communication, the contribu-tion of 3D printing technology to the implementation of precision medicine is significant. Current research shows that 3D printing technolo-gy may significantly improve the clinical skills of foot and ankle surgeons, optimize the surgical process, enhance the doctor-patient rela-tionship, improve doctor-patient communication, build up patients' cognition of the disease, and have a positive role in improving the over-all medical behavior.
