• Angled view of ‘clavicle

27. Imaging of AC joint
• Specific views for AC joints
1. 30 deg. tube angled cephalad (demonstrate joint
enface)
2. 30 deg. angled caudally (demonstrates it tangent)
Plays a crucial role in ‘DX of tendinous lesions
Provide valuable information about bony contours &
tendon calcification
Acromio-humeral space- <5mm is indicative of tear
in ‘supraspinatus tendon.

’Rhomboid ligament (costoclavicular ligament) is attached to ‘inferomedial aspect of ‘clavice & inserts in to ‘1st costal cartilage. In ~ 5 % of individuals, an irregular groove in ‘clavicle, termed ‘rhombiod fossa, is present at ‘site of origin of ‘rhomboid ligament & should not be mistaken for a pathological entity. Lateral end provide a surface to articulate with ‘acromion process at ‘AC joint. Two further ligaments- ‘Conoid (medially) & trapezoid (laterally) take origin from ‘inferior aspect of ‘clavicle.
, shoulder j is attached proximally to ‘glenoid labrum,w/h is fibrocartilagenous ring that deepens the glenoid fossa, & distally to ‘anatomic neck of ‘humerus, encroching inferiorly on the neck of bone, The effects of fibrocartilegenous ring is to enlarge ‘articular surface by ⅔
