Abstract:Due to complex anatomical structure of the pelvis and serious complications, the diagnosis and treatment of pelvic fracture becomes a complicated issue in orthopaedics.Different types of pelvic fractures have different treatment methods, and the treatment outcomes are unsatisfactory. The 3D printed model can show the type and displacement of pelvic fractures clearly, which not only plays an important role in preoperative diagnosis and planning of pelvic fractures, but also provides new ideas and methods for the personalized design of pelvic implants and the application of intraoperative navigation template. With the rapid development of 3D printing technology, the treatment of pelvic fractures has been improved to a great extent. In this review, we mainly summarize the progress of 3D printing technology in the diagnosis and treatment of pelvic fractures.
