Abstract：Objective To explore the application value of three-dimensional (3D) reconstruction in the treatment of unstable distal radius fracture. Methods Thirty-five patients with unstable distal radius fracture who performed plate internal fixation via a volar approach were randomly divided into observation group (n = 19) and control group (n = 16). Data of CT scanning in research group were imported into MIMICS 13.0 software, then 3D digital model of fracture were reconstructed, and the operation was performed after 3D parameters <br> measurement and simulation surgery; Patients in control group performed conventional surgery. Operative time, intraoperative estimate blood loss and X-ray exposure times, hospital stay, fracture healing time and wrist function 6 months after the operation (according to Gartland and Werley wrist scoring system) were evaluated and compared between two groups. Results The operative time, intraoperative estimate blood loss, X-ray exposure times and hospital stay in observation group were less than those in control group, the differences between two groups had statistical significance (P <0.05). All patients were followed up for 9 months (6-12 months). Six months after the operation, the excellent and good rate of wrist function, as well as frature healing time in observation group and control group was 18/19 and 15/16, (15.6 ± 1.5) weeks and (16.9 ± 1.8) weeks respectively, there were no statistical differences between two groups (P >0.05). No obvious wrist dysfunction were found, also, there were no infection or reoperation due to internal fixator complications in two groups. Conclusions With 3D reconstruction technique, anatomic structure of fracture site of distal radius can be displayed clearly, and the surgical procedure simulation and preoperative planning can be carried out. For unstable distal radius fracture, plate internal fixation based on 3D reconstruction is suitable due to its less operative time, intraoperative estimate blood loss, X-ray exposure times and hospital stay, as well as good function rehabilitation.
