Abusive head trauma
Also known as Shaken baby syndrome · Non-accidental head injury · Inflicted traumatic brain injury · Shaken impact syndrome · Inflicted neurotrauma
Fellowship guide to abusive head trauma in infants and young children: the inflicted shaking-with-or-without-impact mechanism, the clinical picture of encephalopathy with subdural and retinal haemorrhage, the PediBIRN screen and Maguire discriminating features, the imaging and skeletal-survey workup, safeguarding from minute zero, the medical mimics and the triad debate, and the ANZ, UK and US guideline differences.

Red flags
- An infant or pre-verbal child with altered responsiveness, seizures, apnoea, or a bulging fontanelle and no coherent mechanism — image now and treat as possible abusive head trauma while you resuscitate
- Bruising in a non-mobile infant, especially on the ears, neck, torso or in a TEN-4 distribution — bruising in a baby who does not cruise is sentinel and demands a full workup
- An inconsistent, changing, developmentally implausible or absent history for a serious intracranial injury — the history is part of the diagnosis
- Subdural haemorrhage that is multi-focal, inter-hemispheric or of differing ages, with numerous multi-layered retinal haemorrhages extending to the ora — a highly supportive combination for inflicted injury
- Posterior or multiple rib fractures, classic metaphyseal lesions, or fractures of differing ages in an infant — these are high-specificity inflicted-injury markers and must trigger head-injury screening

Overview & Definition
Picture the four-month-old brought in "not behaving normally", limp and grunting, whose parent says he rolled off a low bed an hour ago — but who, on the scan, has a thin inter-hemispheric subdural bleed, cerebral oedema, and a healing rib fracture that nobody mentioned. That gap between the story offered and the injury found is the heart of abusive head trauma, and it is where your clinical reasoning has to start. [1] [3]
AHT is the term the American Academy of Pediatrics adopted in 2009 to replace "shaken baby syndrome", and reaffirmed in its 2020 clinical report, because the older name implied a single mechanism and a single set of findings that the evidence does not support. The diagnosis is not "shaking did this"; it is "this child has inflicted head injury", made on the balance of the history, the examination and the investigations together. [1] [2]
The mechanism is violent, repeated rotational acceleration of the head, usually from shaking, often with an impact at the end of the movement — a force that exceeds anything a short household fall can generate in an infant whose neck is weak and whose brain is soft and water-rich. [1] [2]
Why this matters at fellowship level is that AHT is one of the commonest causes of traumatic brain injury and traumatic death in infants, it carries a heavy burden of lifelong disability, and missing it returns a child to a dangerous home while overcalling it harms a family and breaks trust. Your job is a careful, documented, multi-source assessment, with safeguarding running from minute zero. [3] [9]
