Development prospect of orthopedic rehabilitation medicine based on three-dimensional printing technology / 中国组织工程研究

ABSTRACT

BACKGROUND: The application of three-dimensional (3D) precision printing in orthopedic rehabilitation medicine is attracting more and more attention from clinicians, engineers and researchers. OBJECTIVE: To review the development of 3D printing in orthopedic rehabilitation. METHODS: Relevant documents published from 2011 to 2019 were retrieved from CNKI database, Wanfang database, PubMed database and Elsevier database by computer. The search terms were “3D Precision Printing, Orthopedic rehabilitation medicine, Artificial Intelligence” in English and Chinese. RESULTS AND CONCLUSION: At present, 3D precision printing is the key technology in the application of orthopedic rehabilitation medicine, including medical image processing and 3D modeling, surgical simulation planning system, surgical guide board design, implant design and 3D precision printing equipment. Among them, 3D reconstruction technologies such as multiplanar reconstructions, volume rendering technique, maximum intensity projection, minimum intensity projection and surface shaded display are used to read medical digital data and realize visual medical image processing and 3D modeling, which can improve doctor-patient communication efficiency. The thinking process and intelligent behavior of doctors in rehabilitation surgery can be simulated by computer, and a cloud service center with function similar to the brain intelligence of doctors is created to assist doctors in the planning of rehabilitation surgery. With the aid of personalized rehabilitation surgery guide board design software, the bone graft osteotomy guide board can be used to plan the osteotomy line and osteotomy range for the doctor, which can shorten the operation time and improve the operation safety. Using polymer materials, metal materials, ceramic materials and other materials as 3D printing materials, there are still problems such as poor mechanical adaptation and physiological adaptation. The automation degree of common biological 3D design software is relatively low, which is prone to problems such as unsatisfactory matching between the performance of orthopedic medical devices and the defect site, and single internal pore structure of implants. However, the application of 3D precision printing technology in the immersion rehabilitation medicine teaching system is beneficial to the cultivation of rehabilitation medicine talents combining with interdisciplinary medical workers.
