[Signs of injury in bone findings--analysis and evaluation]

Recent bone finds examined under forensic aspects as well as historic skeletons (mainly dating from the Middle Ages) with a known history as to the cause of death and the place where they were found were studied to develop basic criteria for the assessment of the cause and time of origin of bony defects. With regard to the time of origin it was found that the closer an injury occurs before or after death, the harder it is to distinguish from a perimortal injury. A schematic pattern was worked out for the kind of origin classifying the injuries as to "type of force", "mechanism", "weapon/object" and "effect to the bone", which helps in the forensic assessment of the causes of injuries found on bones.
