Application and progress of three-dimensional printing technology in hip arthroplasty / 中国组织工程研究

ABSTRACT

BACKGROUND: Three-dimensional (3D) printing technology is a new rapid prototyping technology, which has been initially applied in orthopedics, especially in the clinical application of hip replacement surgery. OBJECTIVE: To summarize the application status, existing problems and future development direction of 3D printing technology in hip arthroplasty. METHODS: The relevant articles published between January 2000 and March 2019 were retrieved from PubMed, CNKI and WanFang databases. The keywords were "3D printing, rapid prototyping, additive manufacturing, computer aided, computer-assisted, hip, hip replacement, hip arthroplasty, revision hip arthroplasty" in English and Chinese, respectively. Initially, 1 833 articles were retrieved, and finally 105 eligible articles were included for result analysis in accordance with the inclusion and exclusion criteria. RESULTS AND CONCLUSION: (1) In the clinical application of hip replacement surgery, 3D printing technology Is mainly used to make anatomical models for clinical teaching or preoperative plan, patient-specific surgical guides, customized implants or prostheses. (2) The advantages of 3D printing technology can make up for the deficiency of traditional treatment, and it can help to optimize the surgical plan, shorten the operation time, decrease the bleeding, reduce postoperative complications, improve the accuracy of surgery and clinical results. (3) Individualized treatment with 3D printing technology will become a new direction in hip arthroplasty.
