Summary
Atlanto-occipital dissociation (AOD) is a rare, severe injury. Early diagnosis and ethical decisions are crucial for managing patients with AOD and associated critical care challenges.
Area of Science:
- Trauma Surgery
- Critical Care Medicine
- Neurology
Background:
- Atlanto-occipital dissociation (AOD) is a rare, severe cervical spine injury often resulting from high-energy trauma.
- Historically, AOD has a high mortality rate, with many patients not surviving to hospital admission.
- Recent improvements in prehospital care have increased survival rates, enabling diagnosis but highlighting poor prognoses.

Traumatic Brain Injury l: Introduction
37
DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology.

Secondary Spinal Cord Injury llI: Pathophysiology
68
Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...
