Abstract: BACKGROUND: 3D printing technology can design and construct models, surgical guides and personalized implants or fixture according to the actual condition and treatment demand of patients, which has great application prospects in the repair of traumatic fractures. 
OBJECTIVE: To review the application of 3D printing technology in traumatic fractures. 
METHODS: Web of Science, PubMed and CNKI databases were searched for relevant literature on the application of 3D printing technology in the field of trauma orthopedics published from 2020 to 2024. Chinese and English search terms were “traumatic fracture, 3D printing technology, digital model, surgical guide.” Finally, 60 articles were included for analysis. 
RESULTS AND CONCLUSION: (1) Traumatic fracture is a fracture phenomenon with interruption of bones continuity and destruction of integrity caused by various injurious factors. Improving reduction and healing effects with reliable schemes has become a hot issue that needs to be handled urgently in orthopedics related field. (2) 3D printing technology is a three-dimensional entity technology to meet demands based on digital model data, in which adhesive forming materials (powdered metal or polymer), stereolithography, deposition modeling, and optical polymer spray are used, and it is widely used in the field of digital orthopedic biomedicine. (3) 3D printing technology has played significant advantages in disease diagnosis, preoperative planning, reconstructing fracture 3D model, customizing orthopedic implants, customizing fixation braces and prosthetics, fabrication of surgical guide and repair of bone defects, which can design and construct models, surgical guides, and personalized implants or fixture according to the actual conditions and treatment demands of patients. It can provide new ideas for the treatment of traumatic fractures.

Key words: traumatic fractur, 3D printing technology, digital model, surgical guide, review
