Abstract:
Objective To investigate the relationship between the type of gliding contusion and its mechanism with site of force.Methods The site undergoing contusion and ways of force are respectively determined by skull anatomy location and details of these cases.Then,the 132 specimens of brain,which have been fixed by formalin,are sliced in coronal section and sagittal section and stained with HE,observed under microscope.ResultsGliding brain contusion could appeared at the top and bottom region of brain respectively.Top-injury type,were observed in 65 cases(49.24%),base-injury type,were found in 38 cases(28.78%).There were 29 cases(21.96%) in which contusion could be found at both top and base of brain,we called mixed type.We found that the injury area depend on the ways of force-act:the top-injury type mostly caused by the force on cupular part of pars zygomatica in acceleration,the base-injury type mainly caused by the force on occipitalia in deceleration and the mixed type caused by the force on the boundry of the calvaria and occipital in deceleration.Conclusion The type of gliding contusion is relevant with mechanism and site of force.
