Study of the Biomechanical Behavior of Orbital Fractures Using Finite Element Analysis

Abstract

Aim of The Study : As the biomechanical mechanisms of orbital wall fractures are still under research, two  different fracture mechanisms were tested in a finite element based investigation.

Material And Methods:  Skull models were completed from Multi-sliced computed tomography (CT) images obtained under standard conditions. finer skeletal model and a transient dynamic simulation were used to test hydraulic, buckling force transmission

Results: designing an accurate three dimensional biomodel of the skull is possible using the new programs. Results showed that each set-up led to different orbital fracture patterns, which correlate well with clinical findings. Therefore the conclusion is that different mechanisms may act together explaining the variety of clinical fracture situations

Conclusion: Biomechanical testing has proven to be appropriate in answering questions regarding fracture mechanisms.
