Damage caused by parts of the body, measured as a sort of injury by blunt objects and in forensic practice, there are often. They can occur due fist, palm, nails, shod feet, head, teeth. When the fist arise bruises and even hurt wounds (especially in places where the bone is adjacent close to the skin). Possible fractures (for example, the bones of the nose, jaw, ribs, bruises and a concussion of the brain. Known cases reflex cardiac arrest at impact in the area of the fifth intercostal space on the left, epigastric region, anterolateral the surface of the neck.
Kick Palmar surface of a brush can leave traces in the form of bruises, repeating its shape (Fig. 35).
Blow with the edge of a palm on anterolateral surface of the neck can cause a fracture of the cartilages of the larynx, trauma of the neurovascular bundle and related reflex cardiac arrest. In some cases this injury is the cause of basal subarachnoid haemorrhage.
Compression by fingers usually accompanied not only by the appearance of bruises (respectively terminal phalanges), but abrasions resulting from pressure (Crescent) or slip (stripe) free edge of the nail. Unequal number of bruises and abrasions, for example, on the anterolateral surface of the neck, allows to make the assumption, which hand - right-or left - was carried out by compression.
Blows booted foot may be accompanied by negative imprint parts of footwear, scratches, bruises, broken bones and internal injuries.
Damage teeth human bites are presented in the form of symmetrical arches formed by hemorrhages and sadnenia. These hemorrhages and sadnenia formed by the pressure of chewing surfaces of the teeth and, as their negative imprint, in cases of individual defects and features become important forensic value (Fig. 36).
