Orthopaedic Biomechanics Laboratories
Skull Fracture Research
Currently, there is no reliable
biomechanical model for pediatric skull fractures. The OBL has begun researching
the material and mechanical properties of the developing porcine skull
during impacts in order to better understand the nature of injury on devloping
cranial bone in humans.
project, entitled "A Forensic Pathology Tool to Predict Pediatric
Skull Fracture Patterns," involves the OBL, MSU Forensic Anthropologist
-- Dr. Todd Fenton The
collaborative effort from multiple departments hopes
to generate a computational model for pediatric head injury that will
be used by Forensic Pathologists in cases involving abuse.

OBL's preliminary studies investigated the material properties of
the developing porcine skull. Through experimentation on thin beam
specimens, our researchers hope to examine such properties as failure
strength, energy absorbed and elastic modulus of developing cranial

Computational model of beam specimen during bending
at the OBL will also include impact testing on cranial specimens.
CT Scans will be done at Wayne State University after impact testing
in order to gain a detailed view of fractures on the cranial surface.
The mechanics of the skull fracture propogation will then be examined
in order to generate the final computational model.
