دراسة السلوك الميكانيكي الحيوي لكسور الحجاج باستخدام تحليل العناصر المنتهية

Abstract EN

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.
