Abstract: Objective To investigate the advantages of pre-shaped plate based on 3D printing model in the surgery for clavicle fracture. Methods From October 2018 to October 2019, the medical records of 30 cases of midshaft clavicle fracture were retrieved. The patients were divided into an experimental group and a control group according to whether 3D printing-assisted technology was used or not. The operation time, intraoperative fluoroscopy times, intraoperative blood loss, intraoperative screw replacement times, postoperative DASH score, and complication rate of the two groups were compared. Results The operation time of the experimental group was (42.07±8.34) min, while that of the control group was (56.60±7.69) min. The intraoperative blood loss was (39.53±4.03) mL in the experimental group and (66.27±5.97) mL in the control group. The intraoperative fluoroscopy frequency was (2.80±1.32) times in the experimental group and (6.47±1.55) times in the control group. In the experimental group, the screws were replaced (0.40±0.63) times, while in the control group, the number was (1.13±0.64) times. At the follow-up visit 6 weeks after surgery, the DASH score of the experimental group was 10.80±2.73, and that of the control group was 14.73±2.99. All these indicators between the two groups were significantly different. There were no postoperative complications in the experimental group, and 2 cases in the control group had internal fixation irritation. Conclusion Applying 3D printing technology can reduce the time of minimally invasive fixation and screw replacement frequency, and improve postoperative early shoulder function.
