feet

threatening injuries
18. Separating Accidental from
Inflicted
⢠Age of victim?
⢠Is the history plausible?
⢠Does history change with changing
information given to caretaker?
⢠Does history change when related in
subsequent accounts by other family
members?
19. More Questions
⢠Are there non-familial witnesses to the event?
⢠Is the caretaker defensive, belligerent, hostile,
passive or unconcerned?
⢠Is the social situation in which the event
occurred a high-risk environment?
⢠Most importantly, what else could have
caused the observed injuries?
20. Histories Suspicious for
Abuse
ď Delay in seeking medical attention
ď Discrepant history
ď Fractures in varying stages of healing
ď Extremity plus skull fracture
ď Intracranial injuries plus skull fracture
21. Head Injury
⢠Impulsive loading without impact
whiplash
⢠Struck by moving object causing head
acceleration
⢠Moving head strikes object
⢠Head compression vise
⢠Penetrating
23. Shaken Baby Syndrome
Shaken Impact Syndrome
ď§ Commonest cause of mortality and
long term disability due to physical
abuse
ď§ Age range-newborn to 4 years
ď§ Most occur before babies first
birthday
ď§ Average age: 3-8 months of age
24. SBS/ SIS
ď Inconsolable crying is usual trigger
mechanism
ď Perpetrator grabs infant by the thorax,
upper arms or neck, and violently
shakes the baby
ď Time of shaking-- 5-20 seconds
25. Shaken Baby Intracranial
Injury
⢠Bridging veins from the brain to the dura
tear open and bleed, creating subdural
hemotoma and subarachnoid hemorrhages
⢠Brain strikes the inner skull, causing direct
trauma to the brain and swelling
26. Other Injuries of SBS
⢠Most significant are the retinal and
petechial hemorrhages
⢠Skull fractures with sufficient impact
⢠Posterior rib fractures reflect chest
compression during shaking
⢠Bruising of the head, face, chest, and
other areas or other fractures
27. Head Trauma History
ď Symptoms will begin immediately
ď LUCID INTERVAL âA period of
unconsciousness followed by a
period of apparent recovery (0nly
in adults and adolescents, Never
documented in a child)
28. Abdominal Injuries
ď Organs most Frequently injured
Small Intestine, Liver, Pancreas
ď May not produce dramatic signs or
symptoms Quickly
ď Liver damage most likely Blunt
Uppercut
29. Thoracic Injuries
ď Rib cage
ď Internal Organs-heart,lungs, blood
vessels,nerves,esophagus, trachea,
diaphragm
ď Types of Force: Direct impact
Penetration,Compressions
30. Likely Inflicted Thoracic
Injury
⢠Posterior Rib Fracture
⢠Perforation of the posterior
pharynx or upper esophagus
⢠Chylothorax-Allows Milky Chyle to
leak into thoracic cavity
31. Skeletal Injury
⢠Humeral â common in abuse
⢠Femoral-if accidental either motor
vehicle crash or major blunt trauma
⢠Clavicular âuncommon under 3yrs,can
result from shaking
⢠Vertebral-due to compression of
vertebral bodies during shaking
32. Suspicious Fractures

under 2yrs(disc like or
bucket handle)

⢠Medial or lateral
clavicular

⢠Skull
⢠Multiple
⢠Bilateral(longbones
on both sides)
⢠Repetitive(in same
child)
⢠Fractures in hands or
feet
33. Suffocation
⢠Hypoxia-lack of oxygen
⢠Minimal or no external or internal
trauma Petechial hemorrhages may
or may not be present
⢠Overlaying
⢠Wedging
35. Strangulation
ď Manual may have some external marks,
fingerpad bruises,crescent abrasions
ď Ligature may see marks,abrasions, or
bruises from instrument
ď Broken Hyoid, Thyroid,Crioids bone and
cartilage
ď Internal bleeding
ď Petechial hemorrhages
37. IMMERSION BURNS
ď Uniformity of the burn
ď Sparing of skin surface by skin folds
ď Sharply demarcated margins of the burn
ď Most often involve the upper and lower
extremities and the buttocks
38. DRY CONTACT BURNS
⢠Uniform in degree
⢠Often involve exposed surfaces
of the body (arms, legs, hands,
