The purpose of this study was an in depth investigation of the morphogenesis of central and peripheral liver ruptures in blunt trauma and to obtain additional information about their forensic medical significance. It has been established that central and peripheral ruptures are formed by shocks caused by very high forces, as well as by frontal compression of the body as a result of general deformation of the organ and rupture of parenchyma from stretching and tissue shearing. The surface relief of central ruptures was found to be independent of the type of external influence and was determined by the size of the rupture. The peripheral part of such ruptures was characterized by a relatively homogeneous surface topography formed by shear ridges, while the central part was characterized by an inhomogeneous surface topography formed by tensile zones. The surface relief of peripheral ruptures also did not depend on the type of external influence. The surface was relatively homogeneous, with ridges along the edge of the rupture, shear ridges and stretch zones directed deep into the rupture and forming the rupture surface relief in the form of alternating elevations and depressions.
本研究的目的是深入调查钝性创伤中肝脏中央和周边破裂的形态发生，并获取有关其法医学意义的更多信息。已经确定，中央和周边破裂是由极高力量引起的冲击以及由于器官的整体变形和实质因拉伸和组织剪切而破裂导致的身体正面压缩所形成的。发现中央破裂的表面形态与外部影响的类型无关，而是由破裂的大小决定。此类破裂的周边部分的特征是由剪切脊形成的相对均匀的表面地形，而中央部分的特征是由拉伸区形成的不均匀表面地形。周边破裂的表面形态也不取决于外部影响的类型。表面相对均匀，在破裂边缘有脊，剪切脊和拉伸区深入破裂内部，形成呈交替起伏形式的破裂表面形态。
