In Type I, there are non-dislocated fractures present and thus this type is considered as stable. In Type II, the fragments are dislocated. Type II is further subdivided into: Type IIa, when no additional ligamentous injuries or atlanto-occipital instability are present.
Occipital condyle fractures are traumatic injuries that involve articulation between the base of the skull and the cervical spine.
92XB: Unspecified fracture of facial bones, initial encounter for open fracture.
The OC, which is an oval-shaped osseous structure located at the base of the occipital bone, articulates the skull in relation to the cervical spine.
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.
two occipital condylesHumans have two occipital condyles, that are large rounded kidney-shaped projections of occipital bone, that are located contralateral to the foramen magnum and that articulate with the superior facets of the atlas cervical vertebra.
A grade I open fracture occurs when there is a skin wound that communicates with the fracture measuring less than one centimeter.
The Gustilo classification system classifies open fractures based on the amount of energy, extent of soft tissue injury, extent of contamination, or arterial injury to determine the severity of the fracture.
When a fracture happens, it's classified as either open or closed: Open fracture (also called compound fracture): The bone pokes through the skin and can be seen, or a deep wound exposes the bone through the skin. Closed fracture (also called simple fracture). The bone is broken, but the skin is intact.
noun Anatomy. a protrusion on the occipital bone of the skull that forms a joint with the first cervical vertebra, enabling the head to move relative to the neck.
The hypoglossal canal, containing the hypoglossal nerve is located at the base of the occipital condyles.
The occipital condyles are functionally important because they articulate with the superior articular facets of the atlas (C1). This joint functions as a hinge joint allowing flexion and extension of the head. When one shakes their head "no" the two bones move as one piece.
Literature review shows that occipital condyle fractures are rare as isolated injuries and are in many cases accompanied by further injuries to the cervical spine and soft tissue structures, in many cases ending with severe disability. The exact mechanism leading to these injuries cannot always be explained.
Doctors often prescribe medication to manage pain, and most skull fractures will heal on their own over time. The average time for a skull fracture to heal is six weeks.
Injury to the occipital lobes may lead to vision impairments such as blindness or blind spots; visual distortions and visual inattention. The occipital lobes are also associated with various behaviors and functions that include: visual recognition; visual attention; and spatial analysis.
Causes of Occipital Fractures An occipital fracture occurs as a result of sudden, blunt trauma to the base of the skull at the occipital bone. Common causes of occipital skull fractures are: Motor vehicle accidents.
