The Zanca view is a specialized projection of the acromioclavicular joint (ACJ), which will better demonstrate the acromioclavicular joint free from superimposition and aid in the assessment of distal osteophytes.
Why do we see Zanca?
The Zanca view is used in the assessment of acute and chronic acromioclavicular joint injuries. The view optimizes visualization of the acromioclavicular joint, as overlying structures can limit assessment in an AP projection, with distal osteophytes better visualized.
What is the projection used for suspected acromioclavicular subluxation or dislocation?
Indications. The AP view of the acromioclavicular joint is often requested when the referrer either knows about or highly suspects an acromioclavicular joint injury. This projection is quite specific and will not include the shoulder girdle or the entirety of the clavicle.
What type of film should be obtained to best assess for AC separation?
Imaging: This aids in the diagnosis. Plain films are the most common modality, but bone scan, ultrasound, and magnetic resonance imaging may also be used. Stress films are often mentioned in the literature, but are not always worthwhile to obtain in the emergency department.
How do they xray A clavicle?
Position – Patient is erect with arms relaxed and hanging freely at the side. X-ray cassette is behind the patient parallel to thorax. X-Ray Beam – Directed anterior to posterior, perpendicular to cassette (or angled 10-degrees cephalad) and centered at the coracoid.
Is the clavicle axial?
The clavicle (collarbone) is an S-shaped bone located on the anterior side of the shoulder. It is attached on its medial end to the sternum of the thoracic cage, which is part of the axial skeleton.
What is acromioclavicular arthropathy?
The joint between the end of the clavicle and the acromion (Acromioclavicular Joint) moves and rotates with shoulder function. If it becomes inflamed or arthritic, it can produce pain and reduced shoulder function.
How do they XRAY your shoulder?
During the examination, an X-ray machine sends a beam of radiation through the upper arm, and an image is recorded on a computer or special film. This image shows the soft tissues and the bone in the upper arm, which is called the humerus. The X-ray image is black and white.
Will an xray show a AC joint damage?
Vertical (up and down) movement of the clavicle is more common with type III injuries. X-rays show the joint is dislocated.
Do you need an MRI for AC joint?
Magnetic resonance (MR) imaging has a well-established role in evaluation of ACJ pain. MR imaging performed in the coronal oblique plane parallel to the distal clavicle allows assessment of the acromioclavicular and coracoclavicular ligaments owing to its in-plane orientation in relation to these structures.
What does clavicle xray show?
A clavicle series (or clavicle x-ray) is a set of two images taken of the clavicle to determine whether there is evidence of injury or bony abnormality.
What is clavicle xray?
Two anteroposterior (AP) radiographs of the clavicle (with x-ray beam directed at different angles) are appropriate to assess clavicle mid-shaft fractures acutely and to follow these fractures during healing. The clavicle series includes AP in the frontal or thoracic plane and AP with 20 to 30-degrees cephalic tilt.
