| Objective To explore the effect of early clinical application of 3D printing digital planning in the treatment of Dupuytren fracture. Methods A retrospective comparative analysis was conducted on 30 patients with Dupuytren fractures from January 2015 to December 2017. According to the treatment methods, 15 patients were not treated with 3D printing (control group) and 15 patients using 3D printing preoperative planning (3D printing group). The operation time, blood loss, reduction quality, fracture healing time, complications (vascular nerve injury, wound infection, fracture nonunion), ankle function were compared between the two groups. Results All patients were followed up for at least 24 months. In the 3D printing group, the operation time (73 ± 3.155) min and blood loss(105.3±6.681) mL were significantly lower than that of the control group (104±2.024) min and (156.7±11.24) mL. The loss rate of lower tibiofibular reduction in the control group(3 out of 15 cases) was higher than that in the 3D printing group(0 out of 15 cases). There was no significant difference in reduction quality, fracture healing time, and AOFAS functional score between the two groups. Conclusion The application of personalized 3D printing technology can conduct preoperative planning, model training, intuitive understanding of the spatial position of fracture blocks, simulation of reduction of fracture, personalized design of plate and screws, measurement of screw length, which can effectively assist in the treatment of Dupuytren fracture, reduce the difficulty of surgery, shorten the operation time, and improve clinical efficacy. |
