Sections:
The acromioclavicular (AC) joint radiographic series is used to evaluate the acromioclavicular joint and the distal clavicle.
Indications
AC radiographs are performed for a variety of indications including:
- shoulder trauma
- direct blows to the shoulder region
- following a fall onto an adducted arm
- suspected dislocation
- suspected arthritis
Projections
Standard projections
-
AP view
- erect view demonstrating the AC joint in the anteroposterior plane
- best view to inspect widening of the AC joint
Additional projections
-
AP with weight bearing
- also known as a stress view, the patient holds onto a weight on the affected side, placing inferior pressure on the AC joint
- this view is used to rule out displacement when it is suspected yet not confirmed on the AP view
- AP comparison views
- both AC joints are imaged separately, to rule out a suspected displacement or differentially anatomical variation
-
Zanca view
- AP projection with a 10-15 degree cephalad angle to free the AC joint from superimposition
