Simulation of Orbital Fractures Using Experimental and Mathematical Approaches: A Pilot Study.

Area of Science:

• Biomechanics
• Forensic Science
• Anatomy

Background:

• The splanchnocranium, or facial skeleton, is susceptible to injury from blunt force trauma.
• Specific facial bones like the orbit, frontal, and zygomatic bones are common sites of injury.
• Understanding the mechanical response of the facial skull is crucial for injury assessment and treatment.

Purpose of the Study:

• To investigate the mechanical behavior of the human splanchnocranium under simulated brachial violence.
• To determine the forces required to induce fractures in the facial skeleton.
• To provide foundational data for forensic, surgical, and ophthalmological applications.

Main Methods:

• Quasi-static compression laboratory tests were performed on cadaveric skulls.
• Loads were applied incrementally until fracture occurred.
• Experimental and numerical analyses were conducted to assess dynamic behavior.

Main Results:

• A wide range of forces, from 143 N to 1403 N, were observed to cause fractures.
• Significant variability in fracture thresholds was noted.
• The study provides initial data on the splanchnocranium's response to blunt force.

Conclusions:

• The mechanical behavior of the splanchnocranium under load exhibits considerable variability.
• Findings support applications in forensic investigations, surgical planning, and ophthalmology.
• Further research can refine understanding of facial trauma mechanics.
