Macroarchitectonic peculiarities of long bones in the lower extremity

Abstract

Сontemporary forensic practice requires evaluation of the influence of long bones macroarchitecture on the mechanics of their destruction in case of blunt injuries, which finally might enhance validity and evidence of expert’s reports. Therefore objective of the study is obtaining new scientific knowledge concerning macroarchitectural characteristics of the major portions of long bones of the lower limbs, detection of their influence on the regularities of destructive processes of bones in case of blunt injuries. 128 cases with fractures of the lower extremity long bones were examined from forensic-medical practical work, removed from male and female bio mannequins aged from 18 to 65 while conducting forensic expertise. The main morphological parameters (circumference, compact osseous tissue thickness, size and square of the medullar canal) characterizing macroarchitectonics of the femoral, tibial and fibular bones are studied. Their importance and role in occurring fractures of the given bones in forensic practical work are indicated. Different portions of the lower limb long bones possess considerable amount of the structural-functional characteristics. The sizes of the medullar canal (in the form of medullar parameter) and its square influence on the formation of fracture the most considerably among macroarchitectural characteristics.
