Summary
Survivors of traumatic occipitoatlantal dislocation (OAD) are rare, often experiencing severe neurological deficits. Early recognition and respiratory support are crucial for potential treatment, though outcomes remain poor.
Area of Science:
- Traumatology
- Neurosurgery
- Radiology
Background:
- Traumatic occipitoatlantal dislocation (OAD) is a severe ligamentous injury with high mortality.
- Improved prehospital care and diagnostic techniques have led to increased reporting of OAD survivors.
Observation:
- This study retrospectively reviewed three traumatic OAD survivors.
- Diagnosis was confirmed via lateral cervical spine radiography, CT, or MRI.
- All survivors presented with severe neurological deficits; two were children and one was a 64-year-old male.
Findings:
- OAD survivors represented 3.1% of cervical spine injuries in this service.
- Two patients died within two weeks; the anterior OAD patient survived longer but died from septicemia at five months.
- Treatment involved early respiratory support and posterior surgical fusion.
Implications:
- Early recognition and prompt respiratory support are vital for managing OAD.
- Surgical fusion may improve outcomes in select OAD survivors.
- Despite advancements, traumatic OAD remains a devastating injury with a high mortality rate.

01:14Cranial Bones: Superior and Posterior View
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:28Articulations of the Vertebral Column
In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...
01:28Traumatic Brain Injury l: Introduction
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.
