- Bony components of the shoulder include the humerus, scapula and clavicle, which
form the glenohumeral and acromioclavicular (AC) joints.
- The anatomical neck of the humerus and rim of the glenoid cavity serve as attachment
sites for the joint capsule.
- Radiographic examination of the shoulder typically includes AP views of the shoulder with
the humerus in internal and external rotation. Certain shoulder injuries require additional
views such as axillary and/or transscapular "Y" views for proper diagnosis.
