EXPERT ASSESSMENT OF STRENGTH PROPERTIES OF SKULL VAULT BONES

Abstract

One of important issues of expert practice is defining conditions and mechanisms of formation of fractures of skull bones. New data obtained by authors on ratio of organic and inorganic components of bone tissue which testify that at densitometry the inorganic component is responsible for 84,8% of x-ray density, and for 15,2% - organic. The form and degree of expression of anatomic formation has essential impact on distribution of density on skull bones. Close connection of density with other parameters characterizing bone durability shows that it is its important indicator. The received result of performance allows to carry out expert assessment of volume and nature of local fractures of skull more informatively at persons suffering from trauma of various hormonal disorders (hypothyrosis, menopause and so forth) that leads to washing calcium away from bones and to osteoporosis. New data allow estimating the volume of constructional fractures of skull not only depending on a type of external influence, but also from morphological features of contact area.
