Dr. Ebraheim’s educational animated video describes the crucial radiology of the air conditioner joint.
Acromioclavicular joint radiography
Zanca view is acquired by utilizing soft tissue technique in which the voltage is cut into half.
The direction of the x-ray beam: the beam is directed with cephalad of 10 degrees. In case of thought injury the AP view with weight stress (10-20 pound) can be utilized.
Clavicular osteolysis can be examined utilizing the Zanca view.
Osteolysis of the distal end of the clavicle can be caused by recurring tension such as with weightlifting. The acromion will be normal with the problem isolated to the distal clavicle.
MRI will show high signal in the distal clavicle.
Zanca view is also used for medical diagnosis of arthritis of the Air Conditioning joint. It will show osteophytes and joint space narrowing. The findings of the x-rays might not represent the patient’s real symptoms.
Treatment of osteolysis and arthritis of the clavicle is:
– Physical therapy
