What is an occipital condyle fracture?
Occipital condyle fractures are traumatic injuries that involve articulation between the base of the skull and the cervical spine.
What are the cranial nerve affected in occipital condyle fracture?
An isolated occipital condyle fracture is very rare. The condyles are perforated by the hypoglossal nerves, and the jugular foramen lies laterally. The foramen contains the jugular vein and the cranial nerves IX, X, and XI, which can be injured in 33 to 63% of the cases.
What happens when you fracture your occipital bone?
Serious symptoms of a skull fracture include: bleeding from the wound caused by the trauma, near the location of the trauma, or around the eyes, ears, and nose. bruising around the trauma site, under the eyes in a condition known as raccoon eyes, or behind the ears as in a Battle’s sign. severe pain at the trauma site.
What Possesss a single occipital condyle?
The presence of a single occipital condyle in dinosaurs (including birds) and crocodilians is contrasted with the condition in amphibians and synapsids (including mammals such as Homo sapiens), where two occipital condyles are present.
What is the function of the occipital condyle?
The occipital bone is an anteriorly concave bone that forms the base of the cranium. The occipital condyles are paired kidney-shaped structures that form the base of the occipital bone and are the structural bases for the articulation of the skull with the cervical spine.
Why does my occipital bone crack?
Occipital condylar fractures are uncommon injuries usually resulting from high-energy blunt trauma. They are considered a specific type of basilar skull fracture, and importantly can be seen along with craniocervical dissociation.
Can you feel occipital condyle?
The bony skull bump — known as an external occipital protuberance — is sometimes so large, you can feel it by pressing your fingers on the base of your skull.
What is the function of occipital condyle?
Which is the best classification for an occipital condyle fracture?
The classification system widely used for describing occipital condyle fractures is the Anderson and Montesano system 1,2,9 however, as it is purely descriptive, a more clinically-oriented classification has been proposed by Tuli et al 10 which incorporates MRI findings and suggested management 2,5.
What are the different types of skull fractures?
The fractures can be subdivided into three types based on the morphology and mechanism of injury 1,2: type I fracture (~15%) impaction fracture of the occipital condyle. due to axial compression. stable injury. type II fracture (~50%) basilar skull fracture that extends to involve the occipital condyle.
What kind of injury is an OCF?
Object: Occipital condyle fractures (OCFs) are rare injuries and their treatment remains controversial.
When to use halo fixation for occipital condyle fractures?
Management should consist of up-front occipitocervical fusion or halo fixation in cases demonstrating occipitocervical misalignment, or of immobilization in a rigid cervical collar followed by delayed clinical and radiographic evaluation in a spine trauma clinic if misalignment is not present.
