- W4312113431 abstract "Percutaneous reduction and cannulated screw fixation (PR + CSF) for treatment of calcaneal fractures in pediatric patients has been proven to achieve satisfactory outcomes with few complications. But it is also a difficult technology due to the limited exposure and surgeons are unable to reduce articular surface under direct vision. The purpose of this study was to analyze the outcomes of applying 3D printing technology to preoperative preparation and Intraoperative operating for the treatment of calcaneal fractures in children. Pediatric patients with calcaneal fractures from January 2010 to December 2018 were reviewed during study period. Preoperative radiographs and computed tomography scans were collected to classify the fractures, reconstruct 3D printed model and evaluate postoperative outcomes. The blood loss, operative time, number of fluoroscopies, surgeon and patient satisfaction were used to assess the effectiveness, feasibility and safety of 3D printing technology. Functional results were measured by American Orthopedic Foot and Ankle Society (AOFAS) hindfoot score. 12 patients (10 boys and 2 girls) with 17 fractures were involved in our study. There were significant differences in the average Böhler angle before operation compared with that after operation and at last follow-up (P < 0.001). Similarly, the calcaneal height and length postoperatively and at the end of follow-up time were proved to have significant difference (P < 0.05) compared to preoperative. CT scan showed good reduction of the posterior facet according to Goldzak index. The average subjective AOFAS hindfoot score was 94.1. Both patients and surgeon made sense of the 3D printed model that can help them getting more information about the factures and making preoperative plans. No wound complication was found in this study. This study indicated that percutaneous reduction and cannulated screw fixation (PR + CSF) assisted by 3D printing technology in the treatment of calcaneal fractures in pediatric patients achieve good outcomes, with specific preoperative preparation, satisfactory functional recovery and fewer complications.
