Application of three-dimensional reconstruction and virtual surgery for treatment of complex tibial plateau fracture / 中国组织工程研究

ABSTRACT

BACKGROUND:Treatment of complex tibial plateau fracture is a difficulty in orthopaedic trauma. Comprehensive assessment and appropriate surgical plan before surgery are the key points of surgery. OBJECTIVE:To investigate the application value of three-dimensional reconstruction and virtual surgical techniques in assessing and surgical planning of complex tibial plateau fracture before surgery. METHODS:The CT scan data of 30 patients with tibial plateau fracture were imported into the Mimics 13.0 software to establish the three-dimensional digital models of complex tibial plateau fracture, and three-dimensional measurements and reclassification was performed according to three-column classification were made. Virtual surgeries such as bone window operation, reduction of the fracture and bone grafting were made in these models. RESULTS AND CONCLUSION:Reconstructed three-dimensional digital models of complex tibial plateau fracture could indicate the characteristics of fracture accurately, could be observed at any direction, and could help doctors to reclassify the fracture according to three-column classification. Virtual surgeries of bone window operation, reduction of the fracture and bone grafting made in computer by Mimics 13.0 were confirmed to be vividly simulate the clinical surgery, and helpful in estimating the amount of bone grafting. Three-dimensional reconstruction and virtual surgical techniques play an important role in assessing and surgical planning of complex tibial plateau fracture before surgery, which should be a conventional step in the management of complex tibial plateau fracture.
