Shoulder Normal Anatomy

The following radiographs show the normal anatomy of the shoulder.

  • 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.
