- Abstract: BACKGROUND:With the continuous development of medical technology,the treatment of distal radius fractures is facing the need for more precise and personalized treatment.The traditional splint fixation method has some limitations in clinical application,which often has defects such as unstable fixation and easy to occur pressure sores.The validation of the improved 3D printed splint with rapid grid-free simulation is expected to lead to more accurate and effective treatment options for distal radius fractures.OBJECTIVE:To explore the design method of 3D printed splint for distal radius fracture based on clinical defect improvement and verify its clinical efficacy by rapid grid-free analysis.METHODS:Clinical defects of splint fixation of extended distal radius fracture were retrospectively analyzed,and 3D printed small splint was designed with specific improvement.The digital models of traditional splint and improved new 3D printed splint were made by Computer Aided Design drawing.Total,bone,soft tissue,and splint displacement and stress distribution were calculated through simulation analysis using rapid grid-free analysis tools.RESULTS AND CONCLUSION:(1)Compared with the traditional splint,the improved new 3D printing splint exerteded more balanced pressure on the skin without obvious stress concentration,and had better body surface adhesion.The displacement was smaller and the movement range was more reasonable.(2)An 3D printed splint based on clinical defect improvement can be designed.Rapid grid-free analysis verifies the advantages of the improved 3D splint,providing a basis for clinical application.
