Whiplash injuries occur due to differential accelerations in the
human body. Neck injuries predominate, but a considerable body of
clinical evidence suggesting a close relationship between whiplash
and Temporo-Mandibular Joint (TMJ) disorders has also accumulated.
However, the potential injury mechanisms are poorly understood.
This book presents the development of sled-testing of a physical
model of the head, neck and mandible designed to simulate in vivo
behaviour in a low velocity rear end collision. The sled test
results are combined with tensile tests on cadaveric TMJ specimens
to show that excessive levels of mouth opening do not occur during
low velocity whiplash conditions. Active bracing of the jaw muscles
prevents mouth opening. A two-dimensional computational model was
also developed, showing good correspondence to the experimental
tests. A parametric analysis using the model indicated that normal
geometric variations are unlikely to significantly alter the
predicted results from the experimental testing. The results from
this work conflict with the inertial injury theory for the TMJ
during whiplash.
