Background:-Trauma has become an usual accompaniment of modern living. A detailed study of the pattern of injuries sustained may help to reconstruct the whole incident in many cases. In overall visceral susceptibility ,liver is the most frequently damaged abdominal organ.Clinical management of liver injuries depends upon the nature, pattern and severity of injury sustained to that organ. Severe injury to liver alone is sufficient to cause death even in the absence of other vital organ injuries. This study aims at aiding the surgeon to foresee the nature, pattern of injuries that can be sustained to liver in different types of impacts and plan the treatment modalities accordingly. Materials and methods:-A cross sectional study was conducted at government medical college, Trivandrum based on the medicolegal autopsies done for a period of one year. Death following alleged cases of trauma were closely observed. In those cases were liver injury was found were selected for this study. Eighty eight cases of liver trauma were studied. Liver was examined insitu and detailed examination was done after evisceration. Results:-Liver injury was common in occupants of road traffic accidents, as observed in 43 cases(48.86%). Right lobe of liver was more vulnerable and was mainly involved in road traffic accidents. Of the 73 cases (83%)of lacerations, 36cases were found in road traffic occurrence (occupants) , followed by pedestrians (12cases). Contusions and incised wounds were seen in 16 cases (18.8%) and 2cases (2.3%) respectively. Transcapsular lacerations were found to be the commonest 59 cases (80.82%) followed by subcapsular, 11 cases (15%).While considering the disposition the most common nature was oblique found in 34 cases(46.6%) followed by sagittal ,found in 27 cases(37%). Seventy sevencases (87.5%), were due to direct force, followed by transmitted force 10cases, (11.36%). Indirect force was observed in one case (1.14%). Conclusion:-The right lobe of the liver was seen frequently involved both in penetrating and non penetrating trauma .Accidents dominated suicides with respect to liver injuries. Period of survival was inversely proportional to gravity of injury. The amount of blood in the peritoneal cavity depended upon the depth of liver laceration and period of survival. The most common pattern of injury was laceration
