Summary
This video provides a pattern-based approach to interpreting CT scans of craniocervical junction (CCJ) osseous trauma. It aids radiologists in recognizing subtle fractures and alignment abnormalities for accurate diagnosis of cervical trauma.
Area of Science:
- Radiology
- Neuroradiology
- Medical Imaging
Background:
- Craniocervical junction (CCJ) osseous trauma often presents with subtle CT findings.
- Accurate interpretation requires a structured approach and pattern recognition.
Purpose of the Study:
- To offer a pattern-based overview of traumatic bony injuries affecting the CCJ.
- To enhance CT interpretation skills for radiologists evaluating cervical trauma.
Main Methods:
- Presentation of multiplanar CT imaging and 3D anatomical models.
- Review of common CCJ injury types (dissociation, occipital condyle, atlas, odontoid, axis spondylolysis).
- Emphasis on fracture patterns and alignment in axial, sagittal, and coronal planes.
Main Results:
- Illustrations complement CT datasets to clarify spatial relationships and diagnostic features.
- Provides a practical framework for identifying subtle CCJ osseous trauma.
- Focuses on accuracy, pattern recognition, and anatomical clarity.
Conclusions:
- This video resource aids radiology residents and early-career neuroradiologists in evaluating high-energy cervical trauma.
- Enhances diagnostic confidence in identifying CCJ bony injuries through pattern recognition.

01:27Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:08Overview of the Skull
The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...

01:22Sutures of the Skull
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

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,...

01:09Overview of the Axial Skeleton
The skeleton is subdivided into two major divisions—the axial skeleton and the appendicular skeleton. The axial skeleton forms the vertical, central axis of the body. It includes all of the bones of the head, neck, chest, and back. It protects the brain, spinal cord, heart, and lungs. It also serves as the attachment site for muscles that move the head, neck, and back and for muscles that act across the shoulder and hip joints to move their corresponding limbs.

01:17Gross Anatomy of Bone
The two main features of a long bone are the diaphysis and the epiphysis.
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in adults, it...
