Research on the application of digital design and 3D printing technique for the accurate treatment in complex scapular fracture

Objective To investigate the curative effect of the application of digital design and 3D printing technique for the individualized and accurate treatment in complex scapular fracture. Methods A total of 40 patients with complex scapular fracture in Dongguan Shipai Hospital during June 2018 to June 2020 were randomly grouped. The experimental group(20 patients) underwent spiral CT scan of shoulder joint.The data in DICOM format were imported into mimics 15.0 software to reconstruct the three-dimensional model of complex scapular fracture, and the corresponding fracture blocks were simulated to translate and rotate, and the fracture end was virtual reduced. The scapular fracture model after reduction was obtained by 3D printing technology. Preoperative planning was carried out according to the model, and surgical treatment was carried out after shaping the steel plate. Twenty cases in the control group were treated with traditional open reduction and internal fixation. The relevant data during the operation were recorded, and the X-ray and CT were rechecked after the operation. Compared with the preoperative design, the curative effect was evaluated by Hardegger shoulder function score. Results All cases were followed up for 5-13 months. The operation time and intraoperative bleeding in the experimental group were less than those in the control group (P<0.05). There was no significant difference in fracture healing time between the two groups (P>0.05). At the last follow-up, the excellent and good rate was 95% (19/20) in the experimental group and 65%(13/20) in the control group. There was significant difference between the two groups(P<0.05). Conclusion The application of digital design combined with 3D printing technology to formulate treatment plans for patients with complex scapular fractures can meet the requirements of minimally invasive, accurate and individualized, and then can effectively reduce surgical trauma, shorten surgical time and reduce the difficulty of surgical operation, so as to create favorable conditions for patients to recover shoulder joint function faster and better.
