Abstract: [Objective] To investigate the application method and value of 3D-printing technology in surgical planning and operation of the internal fixation through sinus tarsi approach for calcaneal fracture. [Methods] From November 2015 to May 2017, 16 patients with Sanders type or type calcaneal fractures were included into this study. After the spiral CT scanning of calcaneus taken from the patients, digital technology assisted virtual reduction of fracture and personalized plate design were conducted. After that, the patients underwent open reduction and internal fixation with the pre- configured plate and guiders through a limited sinus tarsi approach. [Results] No complications, such as incision necrosis or infection, happened in any patient during 3~6 month follow up. At the latest follow up, Maryland score proved (86.38±7.38) , and the clinical outcomes were graded as excellent in 9, good in 5 and fair in 2 patients, associated with excellent and good rate of 87.50. Regarding to radiographic evaluation, both the B?hler??s angle and Gissane??s angle on the affected side significantly improved, which were not statistically different to the unaffected side (P>0.05) . In addition, the postoperative CT scanning revealed that positions of the plate and screws placed were consistent with those planned preoperatively. [Conclusion] The 3D-printing assisted internal fixation through sinus tarsi approach has advantages of improving fitness of the implants on fractured bone considerably, enhancing efficiency of fixation, and reducing complications related to the incision and implant for Sanders type II or III calcaneal fracture.
