Mimics software can rebuild the data and images gotten in CT, MRI and ultrasound scans into 3D images and display on the computer screen so as to help clinicians understand the type of fracture and the relationship of the 3D structure of the surrounding tissue and to provide a great help in the development of orthopedics operation. OBJECTIVE: To explore the application effect of Mimics software 3D reconstruction on perioperative period of Pilon fracture. METHODS: This study selected 61 cases of Pilon fracture, who received the surgery in the Zhongshan City Xiaolan People s Hospital from September 2008 to September 2013, as research objects. They were randomly divided into 3D group and control group in accordance with the time of admission. All patients underwent anterioposterior and lateral X-ray film examination and multi-slice spiral CT scan. Patients in the control group received internal fixation according to above examination results. Patients of the 3D group, on the base of those of Huang Jian, Attending physician, Department of Orthopedics, Zhongshan City Xiaolan People s Hospital, Zhongshan , Guangdong Province, China Corresponding author: Deng Zhi-cheng, Department of Orthopedics, Zhongshan City Xiaolan People s Hospital, Zhongshan , Guangdong Province, China Accepted: ISSN CN /R CODEN: ZLKHAH 7167

2 . Mimics Pilon the control group, were subjected to internal fixation after three-dimensional entity reconstruction by using Mimics V 10.0 software. Operation time and functional curative effect in the postoperative follow-up were compared between the two groups. RESULTS AND CONCLUSION: The operation time was significantly less in the 3D group than in the control group (P < 0.05). The number of patients with excellent 6-month functional curative effect was more, and the number of patients with poor effect was less in the 3D group than in the control group. The 6-month functional curative effect was better in the 3D group than in the control group (P < 0.05). These results showed that the application of Mimics software 3D reconstruction to the perioperative period of Pilon fractures can give comprehensive assessment of the situation of fracture, optimize and improve the preoperative plan and reduce the risk of surgery, and promote the successful completion of internal fixation.
