What is Fuchs view?
What is Fuchs view?
The closed mouth odontoid AP view (Fuchs view) is a non-angled AP radiograph of C1 (atlas) and C2 (axis).
How do you position an Odontoid?
Patient position
- patient positioned erect in AP position unless trauma the patient will be supine.
- patient’s shoulders should be at equal distances from the image receptor to avoid rotation, the head facing straight forward.
- at the last instant, the patient is instructed to open their mouth as wide as possible.
What is mastoid towns view?
Town’s view: It is an anteroposterior view with a 30 degree fronto-occipital axial tilt. It helps in visualization of the temporal bones of, arcuate eminence, mastoid antrum, superior semicircular canal, internal auditory meatus, cochlea and external auditory meatus.
Where is odontoid process found?
The odontoid process (also dens or odontoid peg) is a protuberance (process or projection) of the Axis (second cervical vertebra). It exhibits a slight constriction or neck, where it joins the main body of the vertebra.
What is AP view xray?
AP, X-ray: An X-ray picture in which the beams pass from front-to-back (anteroposterior). As opposed to a PA (posteroanterior) film in which the rays pass through the body from back-to-front.
What is the central ray for AP open mouth projection?
C: For the open-mouth view, the patient is positioned in the same manner as for the supine AP projection; the head is straight, in the neutral position. With the patient’s mouth open as wide as possible, the CR is directed perpendicular to the midpoint of the open mouth.
Why do we do towns view?
This projection is used to evaluate for medial and lateral displacements of skull fractures, in addition to neoplastic changes and Paget disease.
What is MacEwen triangle?
The MacEwen triangle (also called the suprameatal triangle or mastoid fossa) is a surgical landmark on the surface of the temporal bone just superior to the external auditory canal used to locate the level of the mastoid antrum.
What makes up the head of the fibula?
It is commonly raised as a flap for reconstructive surgery. The fibula runs posterolateral to the tibia and consists of a head, neck, shaft and distal malleolus. The proximal head is irregular with a small superiorly pointed tubercle called the styloid process (formed from the posterior and lateral aspects).
How many avulsions are there in the fibular styloid?
On MR imaging, the fibular avulsion was identified in 11 of the 13 patients. The other two patients had marrow edema in the fibular styloid process, although the avulsion fracture was not evident. All patients had injuries of the posterior cruciate ligament (six tibial avulsions, seven midsubstance tears).
Where does the word styloid come from in anatomy?
In anatomy, a styloid process (from Greek stylos (στῦλος), “pillar”), usually serving as points of attachment for muscles, refers to the slender, pointed process (protrusion) of: Tibia and Fibula – Tibial process, fibular process.
When does the center of the fibula fuse?
The fibula is unlike most long bones where the initially appearing secondary ossification center often fuses last. In the fibula, the upper center appears in the third to fourth year whilst the lower center appears earlier in the first year.
