  • 7. <ul><li>I. Soft tissue injury: </li></ul><ul><ul><li>2-Laceration of an organ: knife wound to the heart (arrow) shown by MRI </li></ul></ul>
  • 8. <ul><li>I. Soft tissue injury: </li></ul><ul><ul><li>3-Abnormal collection of air in the chest -> pneumothorax: Right-sided pneumothorax (arrow) on plain CXR </li></ul></ul>

  • 10. <ul><li>II. Fractures: </li></ul><ul><ul><li>1. Hidden fractures: </li></ul></ul><ul><ul><li>An infant who was hit in the back of the head with a blunt weapon, and sustained a separation of the odontoid process from the body of C2 with anterior subluxation of C1. Note separation of the spinous processes at the level of injury. </li></ul></ul>

Multiple regional fractures -> Long bones -> metaphyseal fractures (avulsion and dislocation of epiphyseal ends): Typical bucket-handle metaphyseal fracture of the distal humerus on plain XR. </li></ul></ul></ul>
  • 14. <ul><li>II. Fractures: </li></ul><ul><ul><li>2. Battered child cases: </li></ul></ul><ul><ul><ul><li>A. Multiple regional fractures -> Long bones -> metaphyseal fractures: </li></ul></ul></ul><ul><ul><ul><li>Corner fractures of the distal femur and proximal tibia </li></ul></ul></ul>
  • 15. <ul><li>II. Fractures: </li></ul><ul><ul><li>2. Battered child cases: </li></ul></ul><ul><ul><ul><li>A.

  • 16. <ul><li>II. Fractures: </li></ul><ul><ul><li>2. Battered child cases: </li></ul></ul><ul><ul><ul><li>A. Multiple regional fractures -> healed lateral rib fractures </li></ul></ul></ul>
  • 17. <ul><li>II. Fractures: </li></ul><ul><ul><li>2. Battered child cases: </li></ul></ul><ul><ul><ul><li>A. Multiple regional fractures -> healed posterior rib fractures </li></ul></ul></ul>
  • 18. <ul><li>II. Fractures: </li></ul><ul><ul><li>2. Battered child cases: </li></ul></ul><ul><ul><ul><li>B. Fractures of different ages: a new rib fracture (arrow) through one of the old, healed fractures. </li></ul></ul></ul>
  • 19. <ul><li>III. Foreign bodies: stabbing by glass </li></ul>
  • 20. <ul><li>III. Foreign bodies: Glass: A beer bottle was smashed against the right frontal area of this victim, producing a fracture (arrows) and shattering the bottle as well. A piece of the bottle penetrated the scalp and stuck in the outer table of the skull (open arrow). </li></ul>
  • 21. <ul><li>III. Foreign bodies: broken blade: Broken knife in the face (arrows) </li></ul>
  • 22. <ul><li>III. Foreign bodies: </li></ul><ul><li>Stab into the head. This is the second unsuccessful attempt to murder this victim. A preceding attempt has left a piece of wire (arrow) above and posterior to the sella. </li></ul>
  • 23. <ul><li>III. Foreign bodies: bullets: </li></ul><ul><li>Fragmented bullet within the head and neck areas of a gunshot wound victim. </li></ul>
  • 24. <ul><li>III. Foreign bodies: bullets: </li></ul><ul><li>A bullet traversed the posterior elements of the C-1 vertebra (small arrows), impacted on the posterior body of C-2 (open arrows), then dropped in the spinal canal before coming to rest at the C-5 level (large arrow). </li></ul>
  • 25. <ul><li>III. Foreign bodies: shots: </li></ul><ul><li>A shotgun wound to the back injured the right kidney. The two pellets overlying the lower pelvis entered the urinary bladder (arrow) after passing through the right ureter. </li></ul>

Deductive identification: </li></ul></ul><ul><ul><ul><li>Sex: radiographs of skull, pelvis and sternum. </li></ul></ul></ul><ul><ul><ul><li>Age: </li></ul></ul></ul><ul><ul><ul><ul><li>Appearance of ossific centers </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Union of epiphysial plates </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Calcification of laryngeal and costal cartilages </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Skull radiographs for examination of fontanels, sutures and teeth. </li></ul></ul></ul></ul><ul><ul><ul><li>Race </li></ul></ul></ul><ul><ul><ul><li>Stature </li></ul></ul></ul>
  • 30. <ul><ul><li>II. Comparative Identification: </li></ul></ul><ul><ul><li>Depends on comparing antemortem to postmortem X-Rays of a person. Comparison includes: </li></ul></ul><ul><ul><ul><li>Normal structures: comparison of skull sinuses especially frontal sinuses regarding the size and shape. </li></ul></ul></ul><ul><ul><ul><li>Abnormal structures: congenital anomalies of bones, deformities and/or fractures. </li></ul></ul></ul><ul><ul><ul><li>Dental radiographs: comparing root shapes, teeth fillings and abnormal teeth eruptions. </li></ul></ul></ul>

  • 32. <ul><li>I. Addictive agents (body packer): </li></ul><ul><li>CT images of a body packer shows multiple drug packages somewhat denser than the bowel, most of which contain entrapped air at the ends of the packages. </li></ul>
  • 33. <ul><li>II. Jewels (larceny by ingestion): </li></ul><ul><li>Radiograph of the abdomen of a suspected jewel thief. Note the dense object (arrow) in the shape of a brilliant cut diamond. </li></ul>
