Forces transmission to the skull in case of mandibular impact

Highlights • A heads’ FEM allowed us to identify injuries induced by a mandibular impact. • During uppercut, decrease of about one-third of efforts chin to the skull base. • Frontal and lateral strikes transfer forces directly to the skull base and occiput. • During the uppercut, part of the impact...

Description
Summary:Highlights • A heads’ FEM allowed us to identify injuries induced by a mandibular impact. • During uppercut, decrease of about one-third of efforts chin to the skull base. • Frontal and lateral strikes transfer forces directly to the skull base and occiput. • During the uppercut, part of the impact energy reaches to the brainstem. • FEM parameters may be adapted to individual characteristics.
