National Pediatric Trauma Group registry findings.
-
Acute distal femur buckle fracture; note absence of healing.
-
Healing distal femur buckle fracture at 2-week follow-up; note sclerotic fracture line and periosteal new bone formation consistent with healing.
-
Linear inflicted bruising extending from arm to back, inflicted by a belt. Same child shown again with back bruising.
-
Overlying linear inflicted marks, which the child disclosed came from a belt. Same child is shown in image of arm and back.
-
CT scan showing liver laceration. Child had severe abdominal bruising (see next image). Caregiver admitted to repeatedly punching the child in the abdomen.
-
Abdominal bruising in a toddler who also had a liver laceration (also see previous CT scan).

Example of ear bruising. Ear bruising is a rare accidental injury. This 10-month-old child was intubated for abusive head trauma (AHT) and spiral femur fracture and had this ear bruising in addition to other facial bruising.

Series of 3 photos of likely accidental hot water scald burn on the leg of an infant. Sparing of skin-to-skin contact areas indicates child was flexed at the knee and ankle at the time of injury, which was consistent with being seated in the kitchen sink. Burn injuries require detailed scene investigation. In this case, investigators confirmed the ease of turning on the faucet and the high temperature of the water from it.
-
Example of strangulation/ligature marks on the neck of a toddler. Strangulation/ligature marks are often linear petechiae and may have fingernail scratches from the victim from struggling to free the airway.
