The present work had the objective to evaluate the existing classifications of damages to the liver associated with a blunt abdominal injury. An original forensic medical classification of hepatic lesions has been developed taking into consideration both localization and mechanisms of blunt abdominal injuries. It is proposed that such injuries should be categorized into three groups: local primary injuries developing as a result of abdominal wall deformation at the site of the application of the traumatic force; local secondary injuries developing in conjunction with the primary ones at the site of the application of the traumatic impact from the fractured costal fragments resulting from chest deformation; late post-traumatic injuries developing simultaneously with the local ones both in the direction of the traumatic force and far away from its application site as a result of the general deformation, displacement, and concussion of the organ. The scope of classifications overviewed in this paper provide a basis for the transition to the next stage of systematization, namely the estimation of morphological features of hepatic injuries depending on the form of blunt abdominal injuries, i.e. blow, compression, etc.
