Összefoglaló szövege

The rise of additive manufacturing, or 3D printing, offers new opportunities in medical technology, reducing surgical time and radiation exposure and improving biomechanical parameters and patient comfort. 3D printed alternatives to plaster casts have become more common in recent years, but further research is needed on production time, cost, and efficiency. The emerging field of in-silico medicine, particularly the rise of finite element analysis, has fundamentally transformed the engineering design process, with widespread applications in biomechanical testing.
The research project aims to develop a workflow for finite element modelling of individual-specific forearm models based on CT scans, through which different forearm fixation solutions can be compared.
In order to create the casts and the finite element model, a 3D scanner was used to scan the right forearm of a healthy male volunteer to create a gold-standard 3D printed fixation by an established company. After printing the designed cast, a CT scan of the volunteer's hand was taken in the fixed state. Based on the 3D scanned surface and the CT scans, a finite element model of the forearm was created by segmentation, together with the gold-standard fixation. The model was also used to simulate a radius and ulna fracture. Based on the model, we developed an alternative cast and integrated it into the forearm model. The casts were tested under a bending moment of 1 Nm and a force load of 400 N in different load cases.
The results show that, with similar biomechanical parameters compared to the gold standard, alternative fixation can reduce printing time by more than 35% (5.5 hours vs 3.5 hours, respectively) and material consumption by more than 48% (313 g vs 161 g, respectively).
The research results will allow the comparison of the biomechanical properties of different fixation solutions and fractures, and are expected to contribute to more accurate treatment strategies, enabling faster development of personalised medicine in orthopaedic care.
The research was supported by the EKÖP-2024-193 New National Excellence Program of the Ministry for Culture and Innovation from the source of the National Research, Development and Innovation Fund.
