Insights
Atlanto-occipital dislocation (AOD) in children is a severe injury from high-energy trauma. Despite poor prognostic indicators, this case shows potential for recovery with prompt treatment and rehabilitation.
Area of Science:
- Pediatric Traumatology
- Neurosurgery
- Spinal Biomechanics
Background:
- Atlanto-occipital dislocation (AOD) is a rare, severe consequence of high-energy trauma, with children being particularly vulnerable due to immature spinal structures.
- Motor vehicle collisions are the primary cause, often resulting in cardiorespiratory arrest, spinal cord injury, or cranial nerve deficits.
Observation:
- A 9-year-old boy presented with cardiac arrest post-motor vehicle collision, diagnosed with AOD and a Chiari I malformation.
- Imaging confirmed AOD and Chiari I malformation; treatment involved occiput-C2 posterior instrumented fusion.
Findings:
- The patient underwent intensive rehabilitation following surgical fusion.
- Recovery included independent ambulation, with a persistent, asymptomatic Chiari I malformation.
Implications:
- This case demonstrates that positive outcomes are achievable in pediatric AOD, even with initial indicators of a poor prognosis.
- Highlights the importance of aggressive management and rehabilitation in pediatric AOD cases.
Background:
Atlanto-occipital dislocation (AOD) is a rare but severe sequela of high energy trauma. Children are at increased risk, due to their immature spine and biomechanical characteristics.
Literature Review:
The prevailing mechanism of injury is motor vehicle collision as passenger. AOD commonly presents with cardiorespiratory arrest, spinal cord injury or cranial nerve deficits. Concomitant injuries, such as traumatic brain injury, are frequently encountered. Diagnosis is made on CT and MRI imaging. Posterior internal fixation is the recommended treatment. Thirty-four percent of patients die, 41 % survive with deficits and 25 % have a complete neurological recovery. Initial symptoms, GCS score and degree of spinal cord injury appear to be predictors of outcome.
Illustrative Case:
We report the case of a 9-year-old boy, who presented in extremis with cardiac arrest after a motor vehicle collision. Upon successful resuscitation, diagnostic imaging showed AOD and a Chiari I malformation. An occiput-C2 posterior instrumented fusion was performed. The patient subsequently received intensive rehabilitation and recovered to independent ambulation, with a persistent, asymptomatic Chiari I malformation.
Conclusion:
This case highlights the potential for positive outcome in paediatric AOD, despite the presence of strong predictors of poor or fatal outcome at presentation.
