Abstract
AIM The purpose of this study was to document the incidence and pattern of cervical spine (c-spine) injuries in children below 36months with inflicted trauma. METHODS An IRB approved, prospective cohort study was performed between July 2011 and January 2016. Inclusion criteria were: age below 36months, loss of consciousness after inflicted trauma, and one initial head computed tomography finding: a subdural, intraventricular, intraparenchymal, subarachnoid hemorrhage, diffuse axonal injury, hypoxic injury, or cerebral edema. A protocol of brain and neck magnetic resonance imaging and angiography was obtained within 48h. Variables were compared by t-test and Fisher-exact test. RESULTS There were 53 children (median age: five months; range: 1-35months), 38 males (71.7%), of which seven died (13.2%). C-spine injury was identified in 8 (15.1%): ligamentous injury (2), vertebral artery shear injury (1), atlantooccipital dissociation (AOD) (1), cord injury with cord epidural hematoma (2), and isolated cord epidural hematoma (2). Retinal hemorrhages (p=0.02), shaking (p=0.04), lower Glasgow coma score (GCS) (p=0.01), brain infarcts (p=0.01), and hypoxic/ischemic injury (p=0.01) were associated with c-spine injury. One with AOD died. Six had significant disability. CONCLUSION For small children with inflicted trauma, the c-spine injury incidence is 15.1%. The injury pattern includes retinal hemorrhages, shaking, lower GCS, and brain injury. Evaluation of shaken infants should include c-spine imaging. LEVEL OF EVIDENCE Level 2 A- This is a prospective cohort study with complete follow-up to hospital discharge or death. In all cases, inflicted trauma was confirmed. Owing to the nature of child abuse, the precise time of injury is not known. All children underwent a strict imaging protocol on arrival to hospital that was supervised on a prospective basis.

Abstract
Cervical ganglia and nerve root injury with resultant paralysis of the phrenic nerve is proposed as a mechanism of injury in “shaken baby syndrome” or nonaccidental head injury of children. We report autopsy findings of a 22-month-old girl in which cervical ganglia and nerve hemorrhage was present along with the triad of encephalopathy, bilateral retinal hemorrhage, and bilateral subdural, intradural, and subarachnoid hemorrhages. Clear evidence of near immediate respiratory arrest was documented from first responder medical reports, juvenile witness statements, and perpetrator confession. The narrowing of time of injury from the anatomic findings at autopsy allowed investigative efforts to focus on a single individual and cleared several other adults with access to the child. Additional technical notes based on our experience are provided for users of cervical neck dissection. Hemorrhage in the tissues surrounding the vertebral artery raises a potential additional injury site in cases of neck injury.

Abstract
Spontaneous subarachnoid haemorrhage (SAH) in children is uncommon, but is sometimes seen after rupture of aneurysms, and in different disorders. Traumatic SAH is common after serious accidental head injury, but is also reported after child abuse with vigorous shaking. To avoid unnecessary accusations of innocent care givers, it is important not to misinterpret the findings as abusive head trauma in small children with SAH. In the presented case, a nearly two-year-old girl was brought to the hospital after a fall witnessed by her father. The girl was unconscious, with elevated intracranial pressure, SAH and bilateral retinal haemorrhage (RH). She was pronounced dead after 9h. Premortem angiography revealed a dissection of the right vertebral artery, and postmortem examination revealed a traumatic lesion deep in the neck, at the base of the skull. Cerebral edema, in combination with SAH and RH, is highly suggestive of abusive head trauma. However, no external lesions, no skeletal lesions, especially no long bone metaphyseal lesions, or subdural haematomas occurring at the same time as SAH, were found. There was no report of previous child abuse in the family. Based on the radiological and postmortem findings, we believe that an accidental fall caused a blunt force trauma with a subsequent dissection of the right vertebral artery. To our knowledge, accidental tear of one of the vertebral arteries, leading to SAH in a toddler, has previously not been described. Child abuse is an important exclusion diagnosis with serious legal implications.

Abstract
OBJECT In this study, the authors estimate the prevalence of injuries to the soft tissue of the neck, cervical vertebrae, and cervical spinal cord among victims of abusive head trauma to better understand these injuries and their relationship to other pathophysiological findings commonly found in children with fatal abusive head trauma. METHODS The population included all homicide victims 2 years of age and younger from the city of Philadelphia, Pennyslvania, who underwent a comprehensive postmortem examination at the Office of the Medical Examiner between 1995 and 2003. A retrospective review of all available postmortem records was performed, and data regarding numerous pathological findings, as well as the patient's clinical history and demographic information, were abstracted. Data were described using means and standard deviations for continuous variables, and frequency and ranges for categorical variables. Chi-square analyses were used to test for the association of neck injuries with different types of brain injury. RESULTS The sample included 52 children, 41 (79%) of whom died of abusive head trauma. Of these, 29 (71%) had primary cervical cord injuries: in 21 there were parenchymal injuries, in 24 meningeal hemorrhages, and in 16, nerve root avulsion/dorsal root ganglion hemorrhage were evident. Six children with abusive head trauma had no evidence of an impact to the head, and all 6 had primary cervical spinal cord injury (SCI). No child had a spinal fracture. Six of 29 children (21%) with primary cervical SCIs had soft-tissue (ligamentous or muscular) injuries to the neck, and 14 (48%) had brainstem injuries. There was a significant association of primary cervical SCI with cerebral edema (p = 0.036) but not with hypoxia-ischemia, infarction, or herniation. CONCLUSIONS Cervical SCI is a frequent but not universal finding in young children with fatal abusive head trauma. In the present study, parenchymal and/or root injury usually occurred without evidence of muscular or ligamentous damage, or of bone dislocation or fracture. Moreover, associated brainstem injuries were not always seen. Although there was a significant association of primary cervical cord injury with cerebral edema, there was no direct relationship to brainstem herniation, hypoxia-ischemia, or infarction. This suggests that cervical spinal trauma is only 1 factor in the pathogenesis of these lesions.

Abstract
The discussion surrounding shaken baby syndrome (SBS) arose from the lack of evidence implicating diffuse axonal injury (DAI) as a cause of death. It was assumed instead that injury to the cervical cord, medulla, and nerve roots played a causal role. The present pathomorphological study examines 18 selected infants (<1-year-old) whose deaths were highly suspicious for SBS, exhibiting the classical SBS triad of acute subdural hemorrhage (SDH), retinal bleeding, and encephalopathy. Gross autopsy and microscopic findings of these infants were compared with those of 19 victims of sudden infant death syndrome (SIDS; control group 1) and of 14 infants who died of disease or injuries/violence not involving the head, neck or eyes (control group 2). Symptoms of mechanical impact to the head were evident in seven of the SBS infants, but in none of the control infants. DAI was not detected in either the SBS or control cases. Localized axonal injury (AI) was regularly present in the brains of the SBS infants surviving longer than 1.5-3.0 h, but only occasionally in the craniocervical junction and within the nerve roots of the upper cervical cord; it was never present in the medulla. Epidural hemorrhage of the cervical cord was seen in four of the ten examined SBS cases, but in none of the control cases. Based on the absence of DAI in the brain and of signs of generalized cervical cord or nerve root injuries, we conclude that the cause of death in the SBS victims was a global cerebral ischemia secondary to SDH, focal vasospasm, trauma-induced transitory respiratory and/or circulatory failure.

Abstract
Pediatric spine and spinal cord injury are rare sequelae of intentional trauma. They may easily be overlooked, however, and probably represent an underreported phenomenon. Recent autopsy data analyzed in conjunction with prior case series indicate that injury to the upper cervical spine and brainstem may significantly contribute to the major morbidity, mortality, and neuropathology in shaken infants. The findings in the previous case report illustrate several important points regarding spine and spinal cord injury after intentional trauma. First, the very young are susceptible to severe, higher cervical injury of both spine and spinal cord. Second, spine and spinal cord injury were initially overlooked because of masked neurologic findings with the concomitant head injury and multiple other systemic injuries. Finally, the child's outcome with significant cognitive delay because of global brain injury in conjunction with the focal high cervical cord injury may support the hypothesis that hypoxic damage could have occurred secondary to brainstem and high cervical cord injury. At the authors' institution, a detailed history and vigilant physical examination are stressed. When the mechanism of injury reported in the history is incongruous with the physical or initial radiographic findings and intentional trauma is suspected, a full skeletal survey, ophthalmologic evaluation, and social evaluation is undertaken. MRI and CT scanning are individualized according to the clinical assessment.
