Abstract:

BACKGROUND: The rapid development of medical data visualization technology and constantly permeate to the medical field make a fundamental change in diagnosis and treatment of orthopedics. The changes are developing toward the “precision, individuality and minimally invasive”, and the medical data visualization technology has become an important means in the clinical orthopaedic surgery.
OBJECTIVE: To determine the breakthrough of research by analyzing the application of digital technology in complex orthopaedic surgery.
METHODS: The PubMed database, Wanfang database, VIP database and CNKI database from 1990 to 2011 were searched by the first author with the key words of “personalized navigation template, digital anatomical models, screw internal fixation, reverse engineering technology, rapid prototyping technology”. The literatures were related to the research on the navigation template preparation process and technology, the study of finite element theory, and the experimental and clinical applications. The old and repetitive literatures were excluded as well as the literatures have nothing to do with this article.
RESULTS AND CONCLUSION: The navigation template reconstructed by digital technology provides a new method for orientation and directional fixation of orthopaedics bolts internal fixation. The individual navigation templates can be made by the digital reconstruction technique, and closely stick to the corresponding anatomical structure for the navigation puncture, then the accurate positioning and orientation are completed, which has a irreplaceable significance for the complex orthopaedic surgery, especially the anatomical structure deformity patients. It lays a good foundation for clinical surgery design and improves accuracy and safety of the surgery.
