Introduction of the modern 3d modeling method into the theory and practice of forensic medicine ballistics, caused by gunshot wounds inflicted by firearms with 9mm caliber ammunition.

Objective: Aim: To explore the capabilities of the modern 3D modeling method for various elements of gunshot wounds caused by 9 mm caliber bullets, intending to integrate these findings into the theory and practice of forensic medicine.

Patients And Methods: Materials and Methods: The research began with a series of experimental shots, during which the morphological features were examined through their 3D spatial reconstruction. The entire series of experimental shots was conducted using an automatic pistol IZH 70-01 equipped with 9.

Forensic morphological signs characterizing stability of the femur, tibia and fibula during effect of external destructive load.

Objective: Introduction: Fractures of the lower limb bones very often become the subject of forensic expertise when experts have to determine the mechanisms of fracture formation, make retrospective restoration of conditions of their occurrence, solve the issues concerning the possibility of their formation under certain conditions. The aim of study is directed to investigation of morphological signs facilitating solidity of the osseous tissue of the lower limb long tubular bones, and therefore, promoting biochemical processes of their destruction in case of external traumatic impact.

Patients And Methods: Materials and methods: Expert investigations included 128 injuries of the long tubular bones of the lower limb: femoral bone - 40 cases, tibia - 46, fibula - 42.

MACROARCHITECTONIC PECULIARITIES OF LONG BONES IN THE LOWER EXTREMITY.

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.

[Morphological changes in tissues of extremities in military personnel with overload disease].

Extremely high physical activity results in anatomic-functional discordance in muscle compartments of segments of extremities. It leads to compartment syndrome consisting in compromised microcirculation, blood plasma infiltration of intercellular space, increased subfascial pressure at the same time we see intraosseous microcirculation disturbance and pathological alterations of bone tissue (hyperostosis, pathological reorganization, fractures), muscles, nerves and fasciae, that is confirmed by morphological alterations. Facsiotomy is of pathogenetic nature in patients with this pathology.

[Magnetic-resonance imaging in the diagnosis of overload injuries of bones].

A comparative evaluation was done of quality of roentgenological and magnetic-resonance imaging (MRI) data for the early diagnosis of overload injuries of bones. 57 servicemen were examined presenting with the above changes at different stages of the pathological process in the bones of the foot, shank, and thighbone. MRI permits detecting changes in stress-induced injuries of bones 2-3 weeks earlier than X-ray does.
